Start, speed up, park…

Lu Zhaoming, an associate professor at Beijing University of Posts and Telecommunications, was sitting in a test vehicle in a parking lot 12 meters underground in the Xiongan New Area. He kept an eye on the position cursor on his mobile phone.

The test vehicle uses "5G + Beidou" positioning and navigation technology.At present, this technology has been demonstrated in Xiongan underground for more than 500,000 square meters, with a positioning accuracy of 2 meters, and the construction cost is only half of the traditional underground navigation technology.

Inspired to channel signals from the sky into the ground

Today, ever-advancing navigation technology makes people’s lives more and more convenient. But many people also have the experience that once they enter a building below the ground, the reinforced concrete will block the navigation signals such as Beidou "clean".

At the beginning of the planning of Xiongan New Area, it was proposed to build "an underground city".This includes about 380 kilometers of underground integrated pipe corridors and over 22 million square meters of underground parking. The precise management of the "underground city" requires high-precision positioning and navigation, and requires new technology and low cost, which can provide replicable samples for other urban construction.

"We compared all kinds of existing technical solutions, and the investment cost became an insurmountable’roadblock ‘," Zhang Qiang, secretary general of the Xiongan New Area Smart City Innovation Federation (hereinafter referred to as the "Innovation Federation"), told the Science and Technology Daily reporter. At the beginning of research and development, as the lead organizational unit for the research and development of underground navigation technology, the Innovation Federation tried almost all mature technical means –

Deploying Bluetooth point beacons in the basement has high construction costs and high operation and maintenance costs;

The addition of Beidou navigation base station indoors cannot afford the high cost of equipment.

Using WiFi positioning requires not only deploying WiFi access points, but also investing in a new network…

Is there a low-cost and effective technical route? Zhang Qiang and the project team members sat around and kept "brainstorming". Proposals, discussions, collisions… More than a week has passed, and there is still no solution.

One evening, the three members of the project team who had discussed nothing stood on the side of the road unhappily. Suddenly, an idea came to Zhang Qiang’s mind: Why can’t we "use local materials" and borrow existing communication facilities – 5G indoor distribution system?

The indoor distribution system is not mysterious, it is a small antenna that looks like a "small mushroom head" that people often see in the corridor or at the door of the house. In 2020, the Ministry of Industry and Information Technology made it clear that 5G indoor signals should be jointly built and shared. Telecom operators uniformly "mix" various signals into the key equipment – the combiner, and the standard 5G indoor signal is then distributed to each "small mushroom head" by the combiner. However, these "small mushroom heads" can only provide communication protection, not positioning and navigation.

"By the way, receive the Beidou signal and forward it with the help of the’little mushroom head ‘!"

This idea made everyone suddenly enlightened. Lu Zhaoming, who was invited to participate in the project team, recalled that in the past, everyone just made a fuss about communication, and no one thought of it.The combination of Beidou signal and 5G indoor distribution system has opened a new door for underground high-precision positioning and navigation.

"That night, I looked at the night sky, and the shadowy Big Dipper was particularly charming." Zhang Qiang said.

Breakthrough algorithms to achieve accurate underground positioning

Walking into the corridor on the sixth floor of the third teaching building of Beijing University of Posts and Telecommunications, Lu Zhaoming pointed to the line above his head and told reporters: "The experimental demonstration of ‘5G + Beidou ‘is carried out here."

The idea of fusing Beidou signals into a 5G indoor distribution system sounds simple, but the implementation process is full of challenges.

The first challenge is how to introduce the Beidou signal underground.In the 5G indoor distribution system, the three telecom operators’ respective 3G/4G/5G and other multi-channel communication signals are transmitted. If a Beidou signal is added, the original communication signal may be interfered, causing the mobile phone to be unable to talk and surf the Internet normally.

"At the beginning, there was nothing I could do. I could only start by analyzing the intermodulation interference model of the two signals and find the fusion algorithm of the signals." Lu Zhaoming said,Communication and Beidou are two types of signals, but they are not mutually incompatible "enemies".The team members calculated the filtering and power parameters required for the Beidou signal to be imported into the 5G indoor distribution system, and then successfully introduced the Beidou signal into the underground through the shared link transmission of broadband multi-channel signals.

The problem of Beidou signal introduction is solved, and the problem of navigation and positioning accuracy emerges.The accuracy of using Beidou signals for positioning outdoors is about 10 meters, but this accuracy is far from enough in the underground environment. Because the distance between two adjacent intersections in the underground parking lot is often less than 10 meters, if the accuracy is not improved, the positioning and navigation will inevitably be wrong.

"This problem has puzzled us for more than a year. During that time, we tried more than 100 different types of algorithms, but the positioning accuracy was not ideal." Lu Zhaoming said that one day, during testing, he accidentally discovered that the wireless reflection environment of Beidou signals in space has static characteristics, which can be used to build data models and provide more location observation sources.

Although the single information of each end point in the parking lot is not accurate, the multi-party information is collected together, and the positioning results will become more and more accurate through the continuous collaborative calibration of the data model.The positioning and navigation strategy was upgraded from "individual combat" to "multi-end point cooperative combat", and a set of positioning algorithms with independent intellectual property rights was born.

In June 2022, in the underground parking lot of Xiongan New District, when Lu Zhaoming saw the positioning cursor move step by step on his mobile phone screen for the first time, he jumped up excitedly.

"This proves that our positioning algorithm and scheme works in actual scenarios!" Lu Zhaoming said.

Pioneering equipment, twisting the "bull’s nose" of independent innovation

In Xiongan New Area, the reporter took a car through a downhill "entrance" and "plunged" into the underground parking lot of Xingqiuyuan in Rongdong District. The navigation map on the mobile phone switched instantaneously, and the arrow guided the vehicle to find the parking space accurately.

In the parking lot, there was neither intricate wiring nor communication equipment crawling all over the wall. There was only a computer room less than 10 square meters at the corner of the passage, and a large amount of equipment was "hidden" here.

"We are’underground workers’," Chu Xinghe, a postdoctoral fellow at Beijing University of Posts and Telecommunications and a member of the project team, told reporters with a smile. Since the experimental verification, the R & D team has spent more than a year debugging and improving equipment underground.

"Here, you must not’judge things by their appearance ‘." Chu Xinghe introduced,Although only a few small boxes are placed on the wall of the computer room, they are like the "heart" of the underground navigation system.The combiner, 5G indoor distribution unit, and Beidou indoor distribution unit rely on these core devices to successfully import Beidou signals and send out positioning signals.

Among these devices, the Beidou indoor distribution unit is the first in the world.The Beidou satellite signal comes to the ground from an altitude of more than 20,000 kilometers, and the signal strength is extremely weak. If it is introduced into the underground computer room, the signal strength will be further attenuated. The project team innovatively developed the receiving module of the Beidou indoor distribution unit, which can amplify the Beidou signal, support feeder transmission up to 1 kilometer, and introduce high-quality signals into the ground.

"The core components in the unit have completely independent intellectual property rights. It can filter the complex signals received layer by layer, remove useless signals, enhance useful signals, and block malicious attack signals to ensure navigation safety." Chu Xinghe said.

In May this year, the Supreme Leader General Secretary pointed out during his inspection of Xiongan New Area that efforts should be made to build a three-dimensional comprehensive transportation network, make full use of underground space, and strive to create a future city without "urban diseases", and truly turn a high-standard urban planning blueprint into a high-quality urban development reality picture.

"In 2025, the ‘5G + Beidou ‘navigation will cover all the built underground parking lots in Xiongan New Area, truly realizing the navigation of’an underground city’."Looking to the future, Lu Zhaoming was full of expectations, "We hope that this technology will be applied to more scenarios such as mining areas, transportation hubs, terminals, etc., and play a greater role in making full use of underground space!"

Hua Qiangu Yaoshen Makeup is stunning – she is not the only beauty whose style has changed

　　The heroines of costume dramas are mostly ill-fated and have experienced many storms. So, how does the same actor want to show the ups and downs of the heroine’s fate, or even interpret the character’s life by one person? The answer is – "makeup".

　　Hua Qiangu – Young Girl to Dementor

　　In costume dramas, the role of the female protagonist’s makeup is more prominent than in modern dramas. Take today’s "Hua Qiangu", which has received a lot of attention, as an example. Xiaogu has gone from an ignorant girl to a long-term study, from respecting the first apprentice to exile in the wilderness, and now to the birth of the demon god. In this ups and downs of the plot, she has to rely on different makeup to express the characteristics of each stage.

Ignorant girl at the beginning of the world

　　Ignorant girl at the beginning of the world

　　Hua Qiangu, who had just grown up, was brutally ostracized by the villagers, but she still maintained a kind heart. At a young age, she had hardly applied Fendai, but her eyebrows had been modified. It was the most popular horizontal eyebrow so far this year, and it was also to show her stubborn and unyielding character.

Long-term learning and artistic love are just beginning

　　Long-term learning and artistic love are just beginning

　　When she arrived at Changliu to learn art, Hua Qiangu practiced hard in order to become an apprentice of His Majesty. Because she had a goal to strive for and knew her admiration for Baizi’s paintings, she always had a crimson color on her cheeks at this stage. Eye makeup was also matched with it, and the eyeshadow was mostly light pink, like a girl who was just beginning to fall in love.

Become the first disciple and become domineering

　　Become the first disciple and become domineering

　　Becoming the first disciple of Baizi’s painting, Hua Qiangu was satisfied, and with the improvement of her cultivation, she gradually showed a hint of domineering. Although the makeup style was not significantly different from when she first entered the long stay, looking at her calm expression stroking the Liuguangqin revealed firmness and determination.

In order to save the master, he risked his life

　　In order to save the master, he risked his life

　　For Hua Qiangu, Bai Zihua was poisoned by the incomprehensible Bu Yuanding. As for Xiao Gu, who forcibly collected 10 divine artifacts to save his master, he was accused by the Immortal Realm and was seriously injured. Hua Qiangu’s face was pale and his lips were completely bloodless, looking very weak.

Cast the Great Cross Exile into the Wild

　　Cast the Great Cross Exile into the Wild

　　Little Bone made a big mistake by stealing the artifact without authorization, and was found to be in love with her master by the pool of unfeeling water, and suffered disfigurement. At this time, Little Bone was physically and mentally exhausted, mistakenly thinking that Bai Zihua had ordered her to be exiled to the wilderness. With pain all over her body, as well as pain in her heart, Hua Qiangu struggled to survive in the wilderness. At this time, in addition to a large scar on her face, the makeup artist also used dark makeup to create a dark yellow complexion without any trace of blood. And in terms of eye makeup, the dark purple with pearlescent effect made her look swollen and lifeless.

The charm of the demon god is unstoppable

　　The charm of the demon god is unstoppable

　　Little Bone broke through the seal and finally became a demon god. At this time, her style changed, and from the beginning of the young girl, she became charismatic and unstoppable. Her eyebrows were elongated and raised diagonally, and her aura was bursting. Thick black eyeliner with blue eyeshadow gradually changed, looking extremely cold. The red lip makeup is sexy and coquettish, echoing the red demon god mark on the forehead, there is a kind of invincible domineering without anger and arrogance.

Zhen Huan – Young girl to powerful Empress Dowager

　　Zhen Huan – Young girl to powerful Empress Dowager

　　In "Empresses in the palace", Zhen Huan entered the palace at the age of 17 and eventually became the empress dowager. After decades, Zhen Huan’s makeup also evolved from pure and elegant at the beginning to vicious and sharp at the end. The change of makeup is also like Zhen Huan’s heart, from innocent with no dispute with the world to cold with revenge.

Entering the palace for the first time – delicate and elegant

　　The first time you enter the palace, you are delicate and elegant

　　After entering the palace for the first time, Zhen Huan’s makeup was elegant and pink, and the curved light-colored eyebrow makeup was soft and simple. The fine upper eyeliner outlined the eyes of God, and the curled eyelashes were modified to make the eyes more sweet. The pink eyeshadow was tender and pleasant, indicating the arrival of peach blossom luck. The pink lip makeup was also indifferent, and Qi Liu Hai’er correspondingly showed Zhen Huan’s simple girlish heart, as cute and pure as peach blossoms.

Revenge Stage – Cold and Shrewd

　　Revenge stage is cold and shrewd

　　After being framed and exploited by intrigue, Zhen Huan at this stage had become a scheming woman and began to fight back coldly. Her fair base makeup made her still beautiful, and the rouge under her cheeks outlined a serious face. The eyeliner raised at the end of her eyes and the sharp eyebrows raised to the sides showed vengeance. The peach lipstick outlined beautiful lips like a danger warning, with a sharp and charming beauty.

Power and government – ruthless

　　The government is ruthless and ruthless

　　The revenge was successful, the queen was taken down, and Zhen Huan’s makeup, which had already mastered everything, also turned completely cold. The slender and sharp eyebrows, echoed by the raised eyeliner, gave the overall eye makeup a severe and fierce feeling, and the dark burgundy lip makeup showed the determination and ruthlessness of a strong woman. The orange blush lost its femininity, replaced by the courage of a powerful woman, which made people shudder.

Wu Meiniang – Soft and charming girl to domineering queen

　　Wu Meiniang – Soft and charming girl to domineering queen

　　Similar to Zhen Huan, Wu Meiniang’s life also went from ignorance to viciousness, and finally reached the peak of power. From the shyness and pure beauty of entering the palace at the beginning, to the beauty and allure of being favored, to the meanness and firmness of the palm of power at the end, the makeup also went from soft to sharp, from pink to dark red, showing Meiniang’s life trajectory step by step.

The girl enters the palace – soft and shy

　　The girl enters the palace soft and shy

　　The skin was so tender that it could pinch out water. Fan Ye easily interpreted a teenage girl entering the palace for the first time. Her elegant flat eyebrows, delicate and cute, and the upper eyeliner was simple and soft, outlining the simple eyes of the shy girl.

Being awarded Zhaoyi – Beautiful

　　Being awarded Zhaoyi is stunningly beautiful

　　The scene of Mei Niang being sealed Zhaoyi is a classic clip in "The Legend of Wu Mei Niang", and this look is called "too beautiful to be human" by netizens. Indeed, Mei Niang, who was favored by Li Zhi, once again stood firm and showed off her brilliance. The bright red lipstick matched the gorgeous clothes, which was beautiful and charming. The slender and elegant eyeliner was charming and alluring, and the red mark on the forehead showed a strong aura.

The pinnacle of power – gorgeous and domineering

　　The pinnacle of power is gorgeous and domineering

　　Meiniang, who had reached the peak of her full strength, was gorgeous and domineering, her slightly raised thick eyebrows were dignified and firm, and the large-area smudged eye makeup at the end of her eyes showed a strong aura and depth. The bright red lips and sharp lips were cold and attractive.

Wu Mengda

　　Looking back on the decades of Wu Mengda’s film career, there are almost no works in which he starred, which are typical supporting roles. However, compared with other full-time supporting actors, Wu Mengda is one of the few actors who have become popular in the Chinese area by acting in supporting roles. Many of his films have starred other movie stars, such as Jacky Cheung and Andy Lau, but most fans’ impression of Wu Mengda is still Chow’s films. Since 1990, Wu Mengda has been very successful by cooperating with Chow Xingchi, and has participated in dozens of Chow’s films, including 、、、、、、、、、 and so on. Among them, "Gambling on the Sage" in 1990 received more than 40 million Hong Kong dollars at the box office, breaking the box office record of a Hong Kong-made film in the past; in 1992, five films starring Chow Xingchi arranged the top five at the box office of the year, three of which were assisted by Wu Mengda; in 2001, he participated in the film again broke the box office record of a Hong Kong-made film in the past, collecting more than 60 million Hong Kong dollars. Over the years, he has cooperated with Chow Xingchi seamlessly and has been dubbed "Gold Green Leaf" by everyone.

　　In a turn of events, Wu Mengda, who is fighting again in this round of rivers and lakes, starred for the first time as the male lead in the groundbreaking new-school comedy "Big Shots". In the film, he played a TV person who was so down that he was drunk all day long. In the process of finding a livelihood, he helped to restore the luster of ancient memories. Stories of little people subverting ordinary lives are not uncommon, and their life comedy is the main theme of this film.

　　"When I was young, I also wanted to be the male lead, but at that time, the male lead was always Chow Yun-fat. I don’t know why I suddenly grew very old after the age of 30, and I didn’t look like playing the male lead, so I had to play the male lead’s father." Looking back at the time of filming, Uncle Da was a model worker, and he had no problem running five plays a day. "I have an average of two plays a month, and more than 20 plays a year. I haven’t slept for the longest six days. I just ran to Leung Chaowei’s side in the morning, went to Chow Yun-fa’s side at noon, changed to Dawn’s side in the afternoon, and returned to Xingzai’s side in the evening. The four heavenly kings all like to play with me, thanks to my mother, who gave me such a cute face."

　　Wu Mengda, an old actor who has played countless supporting roles, laughs that many of the characters can’t even remember himself. "Sometimes I look back at these plays and often say to myself, why was I so cheap back then!" Speaking of his current standards for new films, Wu Mengda said: "Don’t make cameos. There is an old Chinese saying, ‘I would rather be the head of a chicken than the queen of an ox’ means that you would rather be the head of a chick than the tail of a cow. It would have been a good thing to make a cameo in a big play, but I didn’t explain it to the audience. I just took advantage of your fame and had no special significance to the box office. It was just meaningful in publicity. I would rather make some small films and have my own performances. I would basically refuse those cameo roles." "I never cared about whether I was the protagonist or the supporting actor in the play, but one thing, there must be a play," Mr. Wu said frankly.

　　Wu Mengda, who is already a father in his life, believes that he is a good father from a certain perspective, "a good father in terms of taking care of children, but not in terms of time." Because he has been out filming all year round and spends less time with his children, Wu Mengda does not have time to accompany his children to grow up. He also said that if the child likes it, he will not oppose him from entering the entertainment industry. "But the child still needs to grow up, needs to study, and has enough wisdom to judge. This is a very complicated thing." In fact, Wu Mengda’s most wanted role is the father in "Wrong Ride", but he has never had the opportunity. "This father is dumb, has no dialogue, and relies entirely on acting." Wu Mengda laughed and said that because the play was purely tragic, people did not dare to ask him to act.

　　Think small and the world gets bigger; think big and the world gets smaller – for everyone.

Character business card:

Gesture-based user interfaces, if well designed, may be better than traditional button-based operations, especially on larger screens. Google introduced gesture-based navigation in 9.0 Pie as an alternative to traditional navigation bars. And in the latest Pixel 3 and Pixel 3 XL, Google went a step further and made gesture navigation its default and only option, which means that Android’s traditional three-key navigation method has disappeared completely.

On the Pixel 3 and Pixel 3 XL, users won’t be able to disable gesture navigation and opt for the familiar three-button scheme. Importantly, the decision also reflects Google’s overall Android plans for the future. In a response to a user’s question on Twitter, Google’s official @madebygoogle account tweeted: "The Pixel 3 introduces a new model that will represent the way navigation is done on all future Android phones."

This means that gesture-based navigation will become an integral part of Android in the future, not just on Pixel devices. Of course, given the open nature of the Android operating system, Google is unlikely to make it the only option.

That being said, many manufacturers, such as Samsung, OnePlus, Xiaomi, and Huawei, have started rolling out their own gesture-based navigation features with varying degrees of success. Looking to the future, we will definitely see more Android phone manufacturers offering gesture-based interfaces. We just hope that most Android UIs will still have the option to switch back to traditional button-based navigation.

Recently, citizen Xiao Zhang received a brand power bank presented by a cooperative enterprise, but the power bank clearly marked with a capacitance of 10,000 mAh charged the mobile phone once and then ran out of power. Recently, a reporter from Beijing Youth Daily found that many personalized power banks customized for enterprises online are counterfeit products, not only in the name of big brands in the market, but also falsely marked battery capacity. After dismantling these "counterfeit products" power banks, the batteries inside are rusty, and even some power banks use cement batteries.

The "big-name" power bank network sells for less than 20 yuan.

Like Xiao Zhang’s partner companies, many companies would choose to give customers power banks as gifts, and there were also many stores selling customizable and lettering "brand" power banks online. Through the introduction of these sellers, it can be seen that these power banks are called customized power banks because they can print text and patterns, and because the actual capacitance of these power banks can be customized.

In an online store labeled Shenzhen, there are 10 different styles of power banks on sale, many of which are used by some companies as gifts.

In this store, the reporter of Beiqing Daily chose a "Xiaomi mobile power bank" priced at 12 yuan and sold more than 100 times a month. The capacity in the product introduction is 10,400 mAh. From the pictures uploaded by the seller, the shape of the power bank sold is the same as that of the Xiaomi brand. The pictures of the product details used are also the product introduction of the Xiaomi power bank.

After clicking on the purchase button, a reporter from Beiqing Daily saw that options for capacity and logo customization appeared on the purchase page. Optional capacities ranged from 1,800 mAh to 4,800 mAh. Depending on the capacitor selected, the actual price would also vary, ranging from 12 yuan to 19.2 yuan.

In addition, buyers can also buy the packaging and wire corresponding to the selected power bank separately, the price is 12 yuan per set. If you order a large number of packaged power banks, the price of each set is 19 yuan.

After the reporter of Beiqing Daily chose to buy four more mainstream "brand" power banks in the store, he was told by the owner that the power banks photographed were "not for sale, but at least 100 for sale". After many negotiations, the owner agreed to increase the price and sell them separately.

Batteries are rusty
Disassembly sparks fly out

After getting the four power banks purchased, the reporter of Beiqing Daily compared the "Xiaomi Power Bank" purchased with the power bank sold by Xiaomi official, and disassembled the two power banks.

If you don’t look carefully at the appearance, there is basically no difference between "counterfeit products Xiaomi" and the real "Xiaomi". After careful comparison, it is found that the shell of the "counterfeit products Xiaomi" power bank feels rougher than the real "Xiaomi" power bank. The MI mark of "counterfeit products Xiaomi" can see obvious imprints, but the MI mark of the real "Xiaomi" has no imprints. The capacity mark of the tail power bank of "counterfeit products Xiaomi" is darker in color, and it does not feel like the real "Xiaomi" has a raised feeling. The URL of "Xiaomi" written on the back of "counterfeit products Xiaomi" is "xiaomi.com", while the URL written on the back of the real "Xiaomi" is "mi.com".

When a reporter from Beiqing Daily disassembled the two power banks, he found that "counterfeit products Xiaomi" are very easy to disassemble, and the internal components of the power bank can be pulled out by prying open the plastic cover at the top. The real "Xiaomi" has a closed part fixed by screws after prying open the plastic cover at the top. All the screws at the top and bottom must be removed before the internal components of the power bank can be pulled out.

After removing the shell, the circuit boards and batteries of the two power banks were completely different. The circuit boards of the "counterfeit products Xiaomi" were simple and the workmanship was rough. The batteries were wrapped in blue plastic.

After disassembling the plastic outside the batteries of the two power banks, it was found that there were obvious rust marks on the batteries of "counterfeit products Xiaomi".

During the dismantling process, sparks could be seen flying out of the battery anode of "counterfeit products Xiaomi" when it came into contact with metal items such as scissors.

Cement batteries are sold online for 0.24 yuan each.

In addition to the "counterfeit products Xiaomi" power bank, the reporter of Beiqing Daily also dismantled another common polymer lithium battery ultra-thin power bank, which mostly appears in the gifts issued by enterprises. Similarly, the workmanship of this counterfeit products ultra-thin power bank is also very rough, it is easy to be pried open, the circuit board is simple, and the packaging of the battery is only an extremely thin metal film. After the metal film is broken, the liquid overflows, and the taste is very pungent.

As early as 2015, Jiangxi Province had destroyed a power bank counterfeiting den, and the seized "counterfeit products" power bank contained 6 batteries, of which 4 were counterfeit filled with cement.

In various forums and Tieba, some netizens also discovered the "tricks" of inferior power banks, and some netizens disassembled the cement batteries in the power banks. From the disassembly pictures provided by netizens, the reporter of Beiqing Daily saw that some of the cement batteries were filled with sand, while others were filled with cement columns.

In some online shopping platforms, Beiqing Daily reporters found by searching for cement batteries that the price of pure cement core batteries is as low as 0.24 yuan each, starting at 100, and wholesale prices will be lower in large quantities. Some businesses selling cement batteries have power bank components and power banks working in progress.

At the same time, the Beiqing Daily reporter also found that many manufacturers have purchased 18650 batteries used in power banks online at a price of 1 yuan each, with a sales price of about 4 yuan. The price of genuine brand-new columnar 18650 batteries is around 10 yuan.

Low-quality batteries are dangerous
Easily cause fire

What exactly is a customized low-priced power bank battery sold online? The seller of the online store said, "The battery in the power bank he sells is a real battery, a product A battery, not a cement battery used for heavy charging, but a small capacitor, so there will be no short circuit, and long-distance transportation will not catch fire and explode."

Industry insiders told Beiqing Daily reporters that the batteries used in the power banks sold on the market are columnar 18650 batteries and flake polymer lithium batteries similar to mobile phone batteries, while some of the power banks made by "small workshops" use real batteries bought by Beiqing Daily reporters, but the power content is very small, and some use real batteries and fake "cement batteries" for mixed charging.

Generally, if a real battery is used, several batteries are connected together. If it is mixed and assembled, the cement battery will not be connected to the real battery. "The cement battery is placed separately and cannot be powered on when connected together."

The industry insider also said that most of the batteries in "small workshops" are made by the workshop itself or purchased from the outside world, and the safety cannot be guaranteed. If there is a problem with the columnar 18650 battery, it may cause a fire, "because the power content is small, although it will not explode, there will be flames in severe cases." And polymer lithium batteries, if the packaging is not good enough, once the electrolyte in the battery leaks, it will chemically react with the air, which will affect the human respiratory system, and ingestion will endanger the health.

1905 movie network feature In 2017, the total box office reached 55.911 billion yuan, an increase of 13.45% year-on-year. Domestic film box office 30.104 billion yuan, accounting for 53.84% of the total box office; 92 films with a box office of over 100 million yuan, including 51 domestic films. City cinema attendance 1.62 billion, an increase of 18.08% year-on-year.

Looking back on the changes in the film market this year, it is still turbulent and diverse. From the data point of view, the overall trend of the mainland film market is still catching up, with unlimited potential. In 2017, there were 9,597 new screens in the country, and the total number of screens has reached 50,776, surpassing North America to rank first in the world.

　　

Judging from the works, the main theme film and the literary film based on insisting on originality have become two dark horses that cannot be ignored. Among them, the bold attempt of "Wolf Warrior 2" to integrate commercial style not only brought a string of amazing figures in China – single-day box office 426 million, final box office 5.68 billion, but also attracted great attention internationally. It successfully ranked 55th in the top 100 global box office list, once again proving the importance of the main theme film to demonstrate cultural confidence.

　

　 　In addition, the literary and artistic films represented by "Gang Rinpoche" and "Twenty-Two" can break through the encirclement with very few films and become well-known films with quality, which also proves that the audience’s thirst for realistic films has been growing, and the level of appreciation has also been rapidly improved.

　

　　

The impressive market results are also due to the increasingly rational trend of the film market this year. Traffic actors no longer only focus on popularity but also think about acting, and ticketing websites reshuffle to change the distribution power structure. These phenomena can be described as a return to basics after washing away the lead.

　　

The official implementation of the "Film Industry Promotion Law" has also given the film industry a law to abide by, providing a lot of convenience for film creators and a basis for the rectification of industry chaos. Of course, in the journey of the prosperous film market, there are still some episodes that make people reflect. But small cleverness cannot shake the big market.

　

Now, let’s take a look at the top ten keywords of the film market in 2017, and reminisce about this year’s "big surprises and little secrets".

01　Film Industry Promotion Law

　

On March 1, 2017, the "Film Industry Promotion Law" came into effect, providing for the first time in China to regulate and develop the film industry in a legal form.

　

　

As the first industry law in the field of China’s cultural industry, the Film Industry Promotion Law has made clear provisions on decentralizing film approval rights, increasing support for rural films and ethnic minority films, and protecting the rights and interests of audiences.

　

From then on, film censorship will be reduced to the provincial film authorities, and for the issue of film viewing in border areas and ethnic areas, the Promotion Law stipulates that social funds should be actively directed to invest in rural film screening.

　

In addition, for some larger-scale movies, the promotion law also stipulates that theaters should "prompt movies that may cause physical or psychological discomfort to minors and other audiences." Many theaters reminded audiences at online and offline ticket windows during the release of "Wolverine 3."

　

　

As an industry law that regulates the order of the film market, the Film Industry Promotion Law also makes relevant provisions on the protection of film intellectual property rights and the act of stealing and concealing the box office.

　

Film intellectual property rights are subject to law, and piracy, plagiarism, and other acts in the industry will be severely cracked down. For theaters to steal and conceal box office and set up ghost fields, in addition to facing fines, serious circumstances will be ordered to suspend business for rectification. If the circumstances are particularly serious, the original licensing authority will revoke the license.

　

Shortly after the implementation of the Industrial Promotion Law, the competent authorities punished 326 cinemas that had stolen and concealed the box office in 2016, severely cracking down on them, with remarkable results.

The introduction of the "Film Industry Promotion Law" not only directly promotes the film itself, but also the ideology and industrial culture associated with the film, as well as the improvement of the international dissemination ability of Chinese culture and the improvement of the country’s cultural soft power.

Yin Hong

Director of the Film and Television Communication Research Center of Tsinghua University

The Film Industry Promotion Law, as the first industry law in the field of Chinese culture, is not only the culmination of China’s film industry reform experience, but also can escort the continued development of Chinese film.

　

02　Art film

　　

In 2017, several art films broke through the siege under the attack of many blockbusters, gaining a good reputation and box office.

　

The first to bear the brunt is the Tibetan theme of "Gang Rinpoche", the first week of the film box office only 17.03 million, but with people’s word of mouth good word of mouth, the second week of the film box office more than 3 times, the third week is in accordance with 5 times attack.

　

　

In an instant, the discussion of beliefs and the value of life in the film has also become a hot topic in society, and netizens have responded very enthusiastically.

　

Also in this performance is the recently released "Twenty-Two", which uses the experiences of the 22 surviving "comfort women" in the Chinese mainland as a backdrop to objectively present their living conditions.

　

　

The film finally 170 million box office, and evoked people’s memories of that history, causing people to reflect on reality.

　

On the one hand, the two art films that made a comeback at the box office meant that the audience’s appreciation ability was generally improved. On the other hand, it also showed that the audience had an increasing demand for films with realistic themes and films with social topics.

　

Chen Zhixiong

Co-founder and Chief Content Officer of Poisonous Tongue Films

Instead of just asking the audience to yearn for art, sometimes art can also be audience-oriented. We need too much attention to reality, movies with social topics.

Zhou Liming

film critic

The counter-attack of excellent niche films means that the audience’s appreciation ability is generally improved. It does not mean that all films with good reputation can get the box office results they deserve, but at least it announces the end of the era of box office and word-of-mouth inversion.

　

03　Business theme

　　　

If 2016’s "Mekong River Action" allowed us to see the charm of the main theme film commercialization 1.0 for the first time, then in 2017’s "Wolf Warrior 2" and "Army Building", we saw the infinite possibilities of the main theme film commercialization 2.0.

　

The sharp and clean editing, the tight-paced narrative, the cheerful martial arts footage, and the positive theme of home country have all opened up a new path for "Chinese blockbusters," and these elements also make the audience’s blood boil and passion.

　

　　

The box office performance of "Wolf Warrior 2" and "Army Founding" also proves the success of the commercialization of the main theme film. Among them, "Wolf Warrior 2" broke 100 million in 4 hours, the single-day box office 426 million, and the final box office 5.68 billion RMB, which has surpassed the "Mermaid" opening 280 million. The single-day box office reached 310 million and the final box office was 3.389 billion yuan, setting a new record for domestic film box office.

　

　

As a tribute to the 90th anniversary of the founding of the army, the film "The Great Cause of the Founding of the Army" also reproduces the difficult process of the Chinese Communists to create a revolutionary army with its majestic image style and magnificent war scenes, and has won 400 million box office success.

　

It can be said that the high box office of "Wolf Warrior 2" has revolutionized the audio-visual language of domestic main theme films, making the main theme theme the main theme of the market. In addition, the inner theme of the main theme film is more important to bear social responsibility and carry forward the national spirit.

Nowadays, the main theme film is taking up its due social responsibility, not only strengthening "road confidence, theoretical confidence, system confidence, and cultural confidence", but also the main theme film itself is more confident.

Liu Yang

Deputy Editor-in-Chief of the Cultural Interview Room of the Ministry of Political and Cultural Affairs of People’s Daily

The high box office of "Wolf Warrior 2" has broken the curse that has haunted domestic main theme films for many years. The main theme theme can also become the main theme of the market. The key lies in how the characters are shaped and how the story is told.

　

04　Traffic star

　　

In the past two years, the traffic star was the "handle" on the big screen. Its huge fan traffic could make a movie of mediocre quality continuously stir up hot topics, thus driving the box office to improve.

　

However, in such a state, a large number of assembly line works with celebrities as gimmicks appeared in the market, which also gave rise to a lot of industry chaos in which traffic stars "use stunts for performances and rely on pictures for filming".

　

This year, the influence of traffic stars on the performance of a movie has gradually weakened, and the joining of small fresh meat and small flowers is no longer equivalent to high box office, and audiences are gradually returning to the movie itself.

　

　

In the second half of the year, whether it was "The Performer’s Word" or "The Birth of an Actor", a number of programs to discuss performance came into being, inviting many powerful actors to speak out, returning the performance to the essence of art and providing an excellent demonstration to the traffic stars.

　

　　

Zeng Jian

Tencent network film and television team leader

The appearance of streaming stars is not a problem, but in a movie market, only streaming stars are a big problem. People’s demand for streaming stars is real, but people’s demand for excellent acting is also real.　

Chen Zhixiong

Co-founder and Chief Content Officer of Poisonous Tongue Films

We see from movies (works) that the characters of celebrities are getting thinner and thinner, but the noise received from outside movies (works) is becoming more and more noisy.

　

05　original

　

The popularity of IP has ebbed, and the originality has been improved, which is the indicator of the film market in 2017. IP adaptations have been very popular in the past few years. A large number of romance novels and fantasy novels have been brought to the screen, but adaptations themselves are a technical task. If they are not changed well, it is easy to become a mediocre work that relies on piling up stars to cash in, thus losing the soul of the original work.

　

　　

The ebb of IP craze does not mean that IP will withdraw from the market, but that IP adaptations are becoming more rational and no longer blindly followed. At the same time, the power of originality has once again attracted people’s attention and become the focus of the market.

　

This year, many creators have created a number of high-quality films such as "Riding the Wind and Breaking the Waves", "Carnival", "Love and Blind Date" in the spirit of originality.

　

　

In addition to showcasing the imaginative imagination, these films still do not forget to focus the camera on real life, depicting the joys and sorrows of each living individual, resonating with the audience, which is also the charm of originality.

　

Sairen

film critic

In 2017, Chinese films were imaginative and unrestrained, but they still did not forget to carve out individual dignity. And all of this is the source of originality. What is the source is the honesty and bravery of the creator.

　　Draw your mobile phone, order what you need in the WeChat Mini Program, and you can get the goods at the head of the community the next day – community group buying is a new type of consumption model that has emerged in recent years. During this year’s COVID-19 pandemic, community group buying suddenly became popular, providing residents at home with daily necessities, especially fresh fruits and vegetables that are necessary for three meals a day. It has played a huge role in ensuring the normal life of residents during the epidemic prevention and control period, and has also been recognized by more and more people. How will community group buying develop in the future has become a topic of concern for people.

　　Fresh fruits and vegetables become the main commodities of the "group"

　　"My family’s daily necessities such as vegetables and fruits are basically solved by community group buying, and the monthly consumption exceeds 1,000 yuan," Ms. Liu, from Kaifu District in Changsha City, told reporters on April 22. "This kind of community group buying consumption model provides convenience for our working people, the price is relatively affordable, and the quality feels good."

　　The merchant recruits the head of the community as a unit, the head of the group creates a group buying WeChat group, and the head of the group promotes group buying goods in the group. Consumers place an order in the WeChat Mini Program, and the merchant delivers it to the head of the community according to the order volume the next day. Consumers go to the head of the group to pick up the goods, thus completing a community group buying.

　　Group buying platform on the sale of a dazzling array of goods, the reporter in the prosperity of the preferred platform to see, there are 24 categories, ten Hui group also has 14 categories, from fresh fruits and vegetables, food, beauty care to home appliances digital group, and even cleaning services, laundry services can be group, among which vegetables, fruits, snacks, fresh most popular.

　　In the vicinity of Heyuan Community, Kaifu District, Changsha City, there are three group buying points, Xingsheng Preferred, Zhihua Zhiguo, and Shihui Group. There are two group buying groups in the mobile phone of Ms. Zhang, a resident of the community, "I joined two community group buying groups. Each group buying has a different time every day, and the types and prices of sales are different. So when I want to buy something, I will compare the supply of the two platforms before placing an order. There is one platform with better fruit quality, and the other platform has cheaper daily necessities." Ms. Zhang is very knowledgeable about group buying. She said that she has joined community group buying for more than two years. Now most of the daily necessities are solved by group buying, and the number of visits to supermarkets and vegetable markets is much less than before.

　　On the morning of April 24, the reporter saw a truck full of fresh food at the Shihuituan pick-up point in Lotus Pool, Kaifu District. The delivery driver told the reporter that he was responsible for delivering more than ten points around the area, each time there were thousands of orders.

　　The number of Zhihua Zhiguo group buying group in Heyuan Community has reached 492 people, and sometimes the head of the group also sells some local eggs, local chickens, Dongjiang fish and other local specialties. The head of the group buying is mainly middle-aged people, office workers.

　　It is common for several group buying platforms to coexist in a community. Residents of Jinxiu Huatian, Kaifu District, Changsha City told reporters that before the Spring Festival, there was only one prosperous and preferred community. After the epidemic appeared, there are now 4 group buying platforms in the community. Every day, the 4 heads of delegation do their best to promote platform products in the group, which is very lively.

　　In Changsha City, Chengbei Shuiying California Community, the head of the "A Preferred Little Talent" concurrently operates three platforms: Xingsheng Preferred, Koala Selection Mall, and Shihui Group, as well as Deyuan Baozi delivery. Every day at about 8:30 am, she will send the main product links of each platform in the WeChat group to notify the arrival and other information. During the epidemic prevention and control period, she also personally delivered the goods to her door. Ms. Zhou from the community told reporters that because it is far from the urban area and there are relatively few supermarkets, she is more willing to participate in community group buying. The content of the three group buying platforms is similar, all of which are fruits, vegetables, daily necessities, etc., and the prices are slightly different. The price of group buying vegetables and fruits is cheaper than the surrounding fruit shops and supermarkets, such as honeydew melon in Hainan, fruit shops sell for 6 yuan/catty, while the platform only 4 yuan/catty.

　　Community group buying plays an important role during the epidemic

　　"On the fifth day of the first lunar month, there were no vegetables at home. I went to the vegetable market and found that it was not open at all. I went to the nearby supermarket. The vegetable area that had always been dazzling in the past had no leaves. Just when I was at a loss, the owner of the commissary in the community pulled me into the Zhihua Zhiguo shopping platform. The next day, the dishes I bought arrived and felt fresh. Since then, as an office worker, I have been buying fresh fruits and vegetables on the platform every day, which feels very convenient." Recently, Ms. Liu from Yuhua District, Changsha City, told reporters how she became a loyal consumer of community group buying.

　　The sudden COVID-19 epidemic has disrupted the normal life of the citizens, the semi-closed management of the community, and the vegetable market has also delayed the opening of the door. With the extension of the closure time, many residents have no food, and some e-commerce platforms are still delivering goods without interruption. Some community heads also responded positively to the opening of the group, alleviating the residents’ shopping problems.

　　During the most serious period of the epidemic, the reporter found that community group buying was very popular. For example, on the Xingsheng Preferred platform, each single product is tens of thousands of pieces of vegetables, soy products and meat, which are often sold out within 15 minutes of opening the group at 0:00. Some other commodities that are in short supply during the epidemic, such as alcohol, disinfectant, yeast powder, etc., have been out of stock elsewhere, but they are still available on the platform from time to time. As popular products, they need to be snapped up quickly.

　　Ms. Zhou of Heyuan Community said that recently, she has been guarding the two platforms of the community to open a group and stock up on some vegetables every day. It is because of community group buying that her family’s life has not been greatly affected during the epidemic.

　　The frenzy of group buying has ruined the heads of the community. A head of the group surnamed Liu in Lotus Pool, Kaifu District, Changsha City, said that since the opening of the group on the sixth day of the new year, the number of group buying has soared, reaching more than four times the previous number. "During the epidemic, I am so busy that I often can’t eat lunch and dinner." A head of the group surnamed Zhang in Furong District also told reporters that as soon as the delivery truck arrived at 2 pm, in order to prevent the crowding of people taking goods, his family of four went into battle and put the goods in sub-units first.

　　The person in charge of several large-scale group buying platforms in Changsha told reporters that during the COVID-19 epidemic, the sales volume of the platform ushered in explosive growth. For example, in Xingsheng Preferred, Changsha’s super 1 million active users placed orders on the platform, the average order volume increased by about 300%, and the number of new users increased by more than 4 times year-on-year. Fresh goods such as vegetables and fruits were basically sold out before noon.

　　All platforms have tried to ensure delivery during the epidemic. The person in charge of Zhihua Zhiguo told reporters that during the epidemic, the platform also applied for resumption of work early. The first delivery began on February 6, and the growth of vegetables and meat was obvious. In order to ensure that a community with suspected cases can deliver goods, several shareholders also take turns to drive home deliveries. Xingsheng Preferred also took measures such as providing additional subsidies for distribution personnel and setting up incentives to encourage distribution personnel and heads of delegation.

　　Healthy development requires facing existing problems

　　The epidemic has made community group buying widely accepted by people, which is greatly conducive to the future development of this e-commerce model. However, the threshold for community group buying is not high, and many problems such as commodity quality and after-sales services are also exposed during the epidemic. Pay attention to and solve these problems, so that community group buying can better develop and better serve the masses.

　　Group buying has a price advantage, but because you can’t see the real thing, sometimes you will buy troubles: the duck intestines you bought are covered with red spots, the tofu is sour, the vegetables are broken, the melons and fruits are cracked, and the fruit taste is very poor – consumers have a lot of complaints. The biggest difference with other online shopping products is that the fresh fruits and vegetables have a short shelf life, and the goods are particularly easy to break, which brings certain difficulties to after-sales. The sales process includes producers, group buying platforms, community heads, consumers and other links. The responsibilities of each link are not clear. Once there is a problem, mutual accusations and wrangling often occur. Some consumers because the price of goods is not high, defective products thrown away, did not go to complain, but if this happens often, it will definitely affect the group buying feeling.

　　Delivery of goods is also often untimely, which occurs from time to time on various platforms. Sometimes a goods cannot be delivered for several days in a row, and fresh ingredients are not delivered in time, which brings extraordinary trouble and greatly reduces the satisfaction of the shopping experience.

　　Platform in the selection of the community head, there is no threshold, some heads do not even have their own brick and mortar stores, the goods come, just like a stall in the community. A resident of Changsha Yuelu District complained that the community will be a long pile of vegetables, fruits and even meat on the ground, spring and winter season is OK, summer to do? Who is responsible for deterioration?

　　How to protect rights if there is a problem with the goods bought by the group, lawyer Li Chunguang of Hunan Haitian Law Firm told reporters, "If the head of the group buys for free, as long as there is no major fault, it generally does not need to bear legal responsibility; if the purchasing fee is charged, if the purchasing behavior causes the buyer’s loss, it will be legally responsible. Citizens who encounter Sanwu products or quality problems must keep relevant evidence. If the after-sales service of the group buying products is not smooth and there is a dispute, they can use the WeChat chat records and payment records of the head of the group to complain to the Market Supervision and Administration Bureau, or they can request the Consumer Association to mediate or sue to the court."

It has been nearly two months since the launch of the Huawei P30 series, and I previously reviewed the Huawei P30 Pro. The 10x hybrid zoom on the P30 Pro gave me a big shock, allowing us to see the potential of the phone in telephoto shooting, but the 6.4-inch large screen also makes it thicker.

For the author who uses mobile phones heavily, I prefer lightweight and easy to control small-screen mobile phones with one hand. So, I used the P30 as my main mobile phone for a month, and today we will talk about the experience of using the P30.

HUAWEI P30

Appearance: 6.1 inch golden ratio, not tired after long-term use

The most obvious difference between Huawei P30 and P30 Pro is the difference in feel. The 6.1-inch screen of the P30 is more suitable for users with small hands. Although it does not use a curved screen, the sleek middle frame processing of the P30 does not make me feel broken. Compared with the P30 Pro, the shorter screen size also facilitates operations such as drop-down notification bars. One-handed operation is not a problem.

The 3.5mm earphone jack is still retained at the bottom.

In addition to the small screen being more practical and easier, the P30 retains a 3.5mm earphone jack, which is very convenient for listening to music with wired earphones, eliminating the trouble of carrying an adapter cable with you. However, there is still no infrared transmitter on the top of the P30. Friends who want to turn on the air conditioner with their mobile phones need to pay attention. The P30 may not meet your requirements, but now there are many smart air conditioners, which are controlled by mobile APP and WiFi. Without an infrared transmitter, it cannot be considered a flaw.

In terms of color scheme, Huawei P30 and P30 Pro have the same color scheme. They are all five color schemes: bright black, aurora, sky realm, orange, and pearlescent fritillary. There is no difference in color scheme from P30 Pro. If there is a requirement for color scheme, P30 can also meet the purchase needs.

Aurora color looks good

Overall, the appearance of the P30 Pro is not much different from that of the P30 Pro. In addition to the curved screen and the size of the phone, they are more of a functional difference, such as the camera difference we will talk about next.

Take pictures: super photosensitive + 3 times light change night scene is equally powerful

Huawei P30 and P30 Pro use the same CMOS, and Huawei replaced the RYYB array with the IMX600 on the P20 Pro. Compared with the ordinary RGBG array, the RYYB array uses a yellow filter instead of a green filter.

P30 super photosensitive Leica triple camera

This is because the yellow filter can get more light than the green one without changing the size of the single pixel. We will explain to you what RYYB is through a small arithmetic problem.

Let’s first assume that the total amount of RGBG light is 100%, then the RGBG light can be decomposed into 25% red + 50% green + 25% blue. RYYB replaces green with yellow.

RGB three colors

We can see from the above image that yellow is a mixture of green and red, so the light with RYYB can be broken down into: 25% red + [50% red + 50% green (broken down by 50% yellow) ] + 25% blue.

Therefore, the total light input of RYYB’s three colors is 150% of that of RGBG. Of course, this is only a theoretical value. At the P30 series press conference, Yu Chengdong announced that this time it will be increased to 40% of the light input, indicating that RYYB still has room for further optimization.

Since RYYB’s CMOS can absorb 40% more light than traditional RGB arrays, it can obtain clearer photos in low light environments. The thicker spectral structure of the RYYB array also further enhances the limit ISO of the Huawei P30. Although the maximum ISO of the P30 is lower than the 409600 of the P30 Pro, it also reaches 204800.

Is such a high ISO enough? Is the brightness of night shooting lower than that of the P30 Pro?

Previously, I conducted a photo test on the P30 Pro’s extreme low light (article link here). In the extreme low light environment (indoor 0.5lux), the P30 Pro can still take photos with good brightness and clear details. When looking at the sample parameters in these low light environments, I found that the ISO was mostly locked at 25600 and the exposure time was 1/8 second.

It is still far below the limit of the P30 camera, and from the perspective of daily use experience, the difference between the P30 and the P30 Pro is mostly in the telephoto and anti-shake experience.

In terms of telephoto, the P30 uses a 3x zoom lens, while the P30 Pro uses the latest periscope 5x optical zoom lens. Of course, both the P30 and P30 Pro telephoto lenses come with optical image stabilization.

P30 lens combination

In terms of the main camera, although the P30 also uses the CMOS of this RYYB array, there is no additional optical image stabilization, only AIS image stabilization. From the perspective of image stabilization, it is indeed a little weaker than the P30 Pro, but AIS is also sufficient in daily scenes. The handheld 6-second exposure is still stable, and people who have requirements for camera image stabilization can rest assured.

From my actual photo effect, except for the absence of 5x light change, 10x mixed light change, and 50x digital zoom, the other experience is not much different from that of the P30 Pro.

Let’s take a look at the samples taken by the P30, starting with the night.

This was taken just as the sun was setting. It can be seen that the brightness of the night scene shot by the P30 is one of the best, and the lighting suppression is excellent (neither of these two night scene photos has turned on the night scene mode). In the second photo, when the road light is suppressed, the pedestrians in the lower left corner can also see clearly, indicating the powerful quality of this RYYB array CMOS.

Now let’s take a look at the interior sample.

Large aperture mode

It can be seen that the indoor proof P30 also performs well, with a high dynamic range, accurate color reproduction, and the blurring of the large aperture is also in place, and there is no wrong image. Let’s take a look at the outdoor proof during the day.

Large aperture mode

In the daytime light ratio scene, the P30’s performance is also very stable, but it is worth mentioning that the AI assistant will automatically select the appropriate optimization mode for you. For photography Xiaobai, the automatic optimization of AI is indeed very useful.

Finally, let’s take a look at the P30’s zoom capabilities through a set of proofs.

Although this kind of zoom ability cannot achieve the effect of shooting birds, it is enough to deal with the zoom photography needs in daily life (such as shooting blackboards, shooting PPT, etc.). Of course, if you have higher requirements for zoom, it is better to consider the P30 Pro.

Of course, the front lens is also very important, the front of the P30 uses a 32 million pixel lens, let’s find a good-looking lady, directly look at the selfie effect.

From the sample, the beauty effect of the P30 is still good. While whitening and peeling, it still retains the details of the face. You can experience it yourself.

Of course, in addition to taking pictures, the dual-scene video recording function of Huawei P30 series has also been upgraded. After turning on this function, the left side of the picture is the picture shot with a telephoto lens, and it can be changed between 2x, 3x, and 5x zoom. On the right is the wide-angle picture shot by the main camera. While shooting close-ups, wide-angle shooting can also be taken care of.

Double scene video

Displaying both telephoto and wide-angle is a very creative feature for some users who like to shoot videos with their mobile phones. The portrait color retention that debuted in the Mate 20 series last year was also inherited.

Overall, although the P30 camera has some differences in hardware parameters compared to the P30 Pro, there is nothing missing in gameplay. From the perspective of ordinary users (who do not have extreme requirements for mobile phone cameras), the camera quality of the P30 is already excellent enough, and the budget saved on mobile phone lenses can be used to purchase a version with larger storage space.

Screen: 6.1-inch top-of-the-line AMOLED screen, just right for one-handed operation

In addition to the camera being unmatched at the same price, the P30’s screen and performance are also highly competitive at the same price. First, let’s talk about the P30’s screen. The P30 uses a 6.1-inch Samsung AMOLED screen, and the top is also designed with a bangs.

We tested the screen with instruments.

It can be seen that in the bright mode, the P3 color gamut volume of this screen reaches 107.6%, and it maintains an excellent color level – the average color deviation value is delta 0.08, the maximum is delta 0.68, the default color temperature of the screen is 7373k, and the screen quality is excellent.

Performance: GPU Turbo 3.0 full release of Kirin 980 potential

In terms of performance, the P30 is still equipped with the familiar Kirin 980, coupled with the latest GPU Turbo 3.0 and the blessing of the Ark compiler, the system’s fluency has risen to a significant level.

Everyone has seen a lot of Kirin 980’s running score, so I won’t put it here. Let’s look directly at the game performance. I chose NBA2K19 for the frame rate test. The frame rate test results are as follows:

It can be seen that the whole process is 60 frames, and the frame rate basically does not fluctuate. With the blessing of GPU Turbo 3.0, the potential of Kirin 980 has been fully tapped, which also shows us the importance of optimization to SOC performance. Similarly, optimization also greatly improves the fluency of the system.

System: EMUI 9.1 fluency upgrade Huawei Share, the more convenient it is to use

From my personal experience, the P30’s screen following and application switching smoothness when sliding are better than previous Huawei phones. This is of course due to the powerful performance of the Kirin 980, but it is also inseparable from EMUI optimization. We can use the GPU drawing in developer mode to see the smoothness of sliding.

You can see that the reaction time is within the smooth line.

In addition to improving the fluency again, EMUI 9.1 has also made great efforts to beautify the icons. Compared with the icons of the previous EMUI 9.0 system, the icons of EMUI 9.1 are more simple and vibrant, giving people a brisk feeling. With the fresh style of EMUI, it is more suitable for young people to use.

In addition to the superficial changes to the system, Huawei has also made internal optimizations and developed the EROFS file system, which is said to achieve an average of 20% faster random read speed and more free space than the traditional EXT4 file system.

In addition, Huawei’s one-touch function is also very easy to use, but I am not using a Huawei laptop, so I can only show you the one-touch demonstration with the P30 Pro and Huawei Matebook computers. Both the P30 and P30 Pro support one-touch transmission.

Huawei Shared Touch

In addition to one-touch transmission, Huawei Share is also a function I often use in work and life scenarios. To share pictures with other Huawei users, you only need to click the Huawei Share icon, which is convenient and easy to use. Huawei Share’s experience of transferring files between mobile phones is already very close to Apple’s Air Drop, but it needs to be further improved in terms of ease of transferring files with non-Huawei-branded computers.

It can even be shared directly to the printer.

Overall, Huawei’s R & D resources invested in the system over the years have come to fruition, and the impression that the Huawei system is ugly and difficult to use has gradually faded from people’s minds. Hardware and software are walking on two legs. We might as well look forward to the next generation of Android Q upgrades. What will Huawei do?

Battery life: 3650mAh battery life, excellent heavy users can also withstand a whole day

In terms of battery life, the Huawei P30 uses a large 3650mAh battery. From my personal experience, it is completely stress-free to use it for a day from morning to evening. Please see the 5-hour battery life test results below.

In terms of charging, although the P30 is not equipped with the 40W super fast charging on the P30 Pro, it is still equipped with the 22.5W Huawei super fast charging. The 30-minute measured data is as follows.

The actual maximum power can reach 23W

However, in daily use, we may not always carry the charging head, and whether the power bank can fast charge the mobile phone is also a point of our consideration. In actual tests, Huawei P30 supports FCP, SCP and PD fast charging protocols, and there are still many power banks on the market that support these charging protocols.

Summary: 4000 yuan Eslite masterpiece old users call true fragrance

At the end of this experience, I would like to express my feelings about the P30 after using it for a long time.Although the P30 Pro has some trade-offs in camera hardware, wireless charging, dustproof and waterproof, infrared interface, battery capacity, curved screen and other functions compared to the P30 ProBut that doesn’t stop it from being one of the most cost-effective phones at that price.

For the general public who don’t usually take pictures very oftenThe camera function of the P30 is actually powerful enough. At the same price, you can hardly find a phone that takes better photos than the P30.And in terms of the feel of daily use, the smaller and lighter P30 is not easy to use.

In addition to that,Comfortable use with smooth and eco-friendly EMUI, coupled with Kirin 980 and GPU Turbo 3.0 support for games. Excellent comprehensive use experience has allowed Huawei P30 to firmly stand at the price range of 4,000 yuan to 5,000 yuan.

As an "old jazz" who has used Huawei P7, P10, and Mate 20 Pro, this Huawei P30 does make me feel Huawei’s sincerity. Although Huawei has put the most dazzling highlights of the P30 series in the P30 Pro (5x optical zoom), this product strategy makes the P30 look flat as water. But for me as an ordinary user, using the P30 with just the right feel, functional experience, and price is the phone I am really willing to pay for.
