In the noise test, Sylphy is better than Yinglang on the whole, except when cruising at 120km/h, mainly because the noise and vibration control of Sylphy’s four-cylinder engine is better than Yinglang’s three-cylinder engine. When Yinglang’s speed exceeds 2500rpm, obvious noise will be transmitted to the car, while Sylphy is relatively better, and the driving speed is also lower than Sylphy’s CVT gearbox.

Smoke billowed from the Israeli air raid on Gaza.

Israeli air strikes on Gaza have angered people in Arab countries.

　　BEIJING, Dec. 29 (Xinhua)-According to comprehensive reports, Israel has carried out continuous air strikes against the Gaza. Up to now, the attacks have killed 298 people and injured more than 950 people, including both Hamas militants and ordinary Palestinians. It is reported that this is the deadliest conflict in Gaza since the Middle East War in 1967.

　　The Israeli side hinted that it did not rule out escalating the operation and launching a ground attack, and it has begun to increase its troops; Palestinian militant group Hamas has called for suicide attacks. Hamas stepped up its long-range rocket launcher to fight back, reaching 30 kilometers deep into Israel, with the longest range ever.

　　Israel launched several air raids on Gaza in the past two days in retaliation for the Palestinian attacks in recent days, while Hamas repeatedly fired rockets and mortars in response, claiming that it had fired two long-range "hail-type" rockets at Ashdod, a southern Israeli city 30 kilometers from Gaza. Another rocket was fired at Javne, a small town 30 kilometers away from Gaza, which was the longest range of Hamas’s attack.

　　The attack took place on the Jewish Sabbath, which was unexpected. On the other hand, analysts and the media have long expected that Israeli military actions against the Gaza Strip will be inevitable before the Israeli parliamentary elections in February next year.

　　Israel: carefully planned air strikes, army ready to attack

　　From the deep-seated reasons, the attack on the Gaza Strip was the result of the struggle between Israeli political forces before the election. Although they know that there are risks in using force, they still judge that attacking is a more favorable choice for themselves. From the standpoint of the ruling party, this is forced by the election situation. As the air strikes launched by Israel on the Gaza Strip entered the second day, the Israeli Cabinet passed a decision on the 28th to call some reservists.

　　Israeli Foreign Minister Livni said that the operation has been "very successful" so far. She said that Israel is determined to change the reality in Gaza, so that the Israeli public can get rid of the Palestinian rocket attack for four years forever.

　　Israeli local media reported that the Israeli air raid had destroyed 230 targets in the Gaza, and 170 targets were destroyed in the first day. In fact, after a year of intelligence collection and careful deployment, it showed that the use of force was by no means an "improvisation". At present, the Israeli army is mobilizing tanks and ground troops to assemble near Gaza, ready to attack at any time.

　　Cabinet Minister Yitzhak herzog said: "We may not want to conquer Gaza, but of course we are considering all options."

　　Hamas: Resolutely will not surrender and plan to launch a "jihad."

　　Hamas said it would never surrender with a white flag, and warned that it would pay a heavy price if the Israelis invaded Gaza. "All options are on the table, including rocket attacks and suicide bombings," Hamas spokesman Fawaz Bahome said.

　　According to Iranian media reports, Hamas’s foreign propaganda officials even said that "the only way to fight back against Israeli crimes is to launch jihad and uprising". It is reported that Hamas’s strength has not been hit hard by air strikes.

　　The Israeli police have completely cancelled their vacation and issued a high-level terrorist attack alert on the territory to prevent Hamas from retaliating. According to the information held by the Israeli security department, after the Israeli military attacked Gaza, at least 10 terrorist attacks were reported.

Peninsula network August 14 th　Recently, Mr. Sheng, a citizen, reported to the tide listening column of Peninsula Network (0532-80889235) that he spent 450,000 yuan on a Mercedes-Benz EQE in Qingdao Lixingxing Star Automobile Co., Ltd., and found that there was a problem in battery charging during use. The cruising range is greatly reduced. At first, it can charge 96 kWh when fully charged, but now it can only charge 42 kWh when fully charged. There have also been cases where the reversing function has failed. In this regard, the staff of the 4S shop said that after technical testing, the battery was faulty, and the battery replacement process was already being taken to the customer, and both parties had reached an agreement.

At the end of June 2023, Mr. Sheng took a fancy to a Mercedes-Benz EQE in Qingdao Lixingxing Star Automobile Co., Ltd. "At that time, the market quoted 550,000 yuan, and the 4S shop gave a discount of 100,000 yuan, and finally spent 450,000 yuan to buy it." Shortly after Mr. Sheng bought the car, this Mercedes-Benz EQE officially dropped another 100,000 yuan. Mr. Sheng thinks this is a completely understandable market behavior. However, many problems were found during the use of the vehicle.

Mercedes EQE Full battery life can only run 200.How many kilometers?

Mr. Sheng told reporters that the car he bought had problems with its battery life during use. "It is no problem to drive 650 kilometers when you just pick up the car, and then the cruising range is getting shorter and shorter. Now you can only run more than 200 kilometers on full charge. At the beginning of the car, it was fully charged with 96 kWh of electricity. Now it can only be charged with 42 kWh when it is charged in a state of power loss. "

Mr. Sheng also fed back the problem to the Mercedes-Benz 4S shop, and the staff gave it a test. At that time, no fault code was found, indicating that the battery was normal. At the suggestion of the staff, Mr. Sheng found the fast charging pile and consumed less than 10% of the electricity for self-test charging. Mr. Sheng tested that the battery was fully charged from 8% to 100% and found that the charge was still 42 kWh. Mr. Sheng recorded the video of the charging process and handed it to the staff of the 4S shop. "The cruising range shows 650 kilometers when fully charged, but the cruising range drops very quickly during the actual vehicle driving." Mr. Sheng said.

Mercedes EQEThe reverse function appears. "Failure"?

In addition, Mr. Sheng also found that there were problems with the electronic control of his car. "Going out in the morning, in the process of reversing, the display has hung up the reverse gear, but the locomotive has no movement at all." Mr. Sheng turned off the power for many times, but it still failed to restart. So Mr. Sheng called for help. After several attempts by Mr. Sheng, the reverse gear function returned to normal. Mr. Sheng told reporters that for this problem, the staff of the 4S shop also had no fault code and could not detect the problem.

Mr. Sheng told reporters that after many times of communication, the 4S shop promised to replace the battery, but he also had his own concerns. "Replacing the battery will definitely appear in the maintenance record, which will devalue the second sale of your car."

4SStore response: the battery has been replaced for the customer.

In order to implement the situation, the reporter contacted Chengyang Lixingxing, and the staff said that Mr. Sheng’s Mercedes-Benz EQE had been technically tested for battery failure, because during the warranty period, Mr. Sheng had been given the process of replacing the battery. Free battery replacement for Mr. Sheng, and an agreement has been reached with Mr. Sheng. She is not clear about whether there is a problem with electronic control, but she will ask her after-sales colleagues about the situation.

Lawyer: You can claim compensation if the vehicle depreciates.

Do you have the right to ask for extra compensation besides replacing the battery for Mr. Sheng’s experience? Lawyer Niu Hongyan of Beijing Dacheng (Qingdao) Law Firm believes that "if there is evidence to prove the existence of vehicle depreciation or other economic losses, you can claim compensation, but in practice, it is difficult to identify the depreciation loss. In terms of contract correspondence, after the seller bears the liability for vehicle depreciation, it is impossible to claim compensation from the manufacturer. "

　 　In response to the above problems, Peninsula Network will continue to pay attention.

It has been nearly three years since the system was put into trial operation, and the big data system for comprehensive evaluation of radio and television program ratings of the General Administration of China has had a profound impact on the industry. What is the core architecture of the system? How does the system highlight innovation and key applications? What is the focus of the next step? Recently, the reporter of "Radio and Television Review" had an exclusive interview with the person in charge of the Big Data Research Center for Program Comprehensive Evaluation of the Radio and Television Planning Institute of the General Administration.

"Buzz."

　

Walking into the communication network computer room of the big data system for comprehensive evaluation of program ratings of the General Administration of China, the roaring air conditioning sound made the recording pen stop working.

Communication network room of big data system for comprehensive evaluation of program ratings of General Administration of China.

On the rows of racks, hundreds of servers, switches and routers are running at high speed, and countless data are collected, stored and calculated here in binary form, which eventually become a series of professional numbers on the viewing table.

　

The person in charge of the Big Data Research Center for Program Comprehensive Evaluation said: "The viewing data of more than 300 million users (cable TV, IPTV, Internet TV) in China are gathered here, which is equivalent to the’ brain’ and’ warehouse’ of the whole system."

　

On December 26, 2018, the big data system for comprehensive evaluation of radio and television program ratings of the General Administration of China was put into trial operation. In the past three years, relying on the real and pollution-free viewing statistics and analysis, the system has provided important support for public opinion guidance, program broadcast management, etc., and has also become the main reference for daily assessment and advertising investment promotion of TV stations and other units.

　

"National team data", "pollution-free data" and "dehydration data" are the basic cognition of the industry on the big data system for comprehensive evaluation of ratings, but there are not many in-depth issues about how to create, how to operate and what innovative features this system has. Recently, the reporter of "Radio and Television Review" conducted an exclusive interview with the person in charge of the Big Data Research Center for Program Comprehensive Evaluation of the Radio and Television Planning Institute of the General Administration, revealing the origin, operation and development of this system.

　

On-line: an important measure to control viewing fraud from the source

The first appearance of the big data system for comprehensive evaluation of program ratings was at the end of 2018. However, as early as 2016, under the leadership of the State Administration of Radio, Film and Television, the Radio and Television Planning Institute took the lead in organizing a number of radio and television stations, network operators, research institutes, universities and enterprises, and successively carried out research and development of core technologies for viewing, standard formulation and small-scale experiments.

The big data system for comprehensive evaluation of radio and television program ratings of the General Administration of China was put into trial operation.

The person in charge said that for a long time, the CPC Central Committee has attached great importance to the construction of the viewing survey system and demanded the establishment of an authoritative and convincing new viewing survey system to promote the high-quality and innovative development of radio and television. The Party Group of the General Administration has conscientiously implemented the central government’s decision-making and deployment, and taken the construction of a comprehensive evaluation big data system for program viewing as an important measure to implement the spirit of the central government.

　

At the same time, the authoritative comprehensive evaluation of program ratings is also the general trend of the industry. All sectors of society call for the establishment and comprehensive application of a new audience survey system as soon as possible, so as to solve the outstanding problems in the field of audience survey from the source.

　

In this context, the big data system for comprehensive evaluation of program ratings came into being.

　

Attack: complete the system construction in three stages

From 0 to 1, innovative construction.

　

The big data system for comprehensive evaluation of program viewing abandons the traditional viewing survey mode and innovatively builds a new big data viewing survey system with cloud computing, whole network, full sample and big data as its important features.

　

The person in charge bluntly said, "It is very difficult, from data access to system construction, model and index design to system online, all from scratch".

　

Since 2016, the construction process of the system has been divided into three stages with different periods and different key points.

　

In the first stage, the Radio and Television Planning Institute led relevant units to carry out independent research and development of the core technology of viewing survey, formulated and published a number of industry specifications such as viewing data element set, exchange interface and cleaning rules, and independently mastered a number of core technology patents and software copyrights.

　

At the same time, by studying the theory of big data viewing survey, the index system and calculation method are determined to solve the problems of sample analysis, statistical rules and processing methods, data modeling and analysis of big data viewing under the new situation.

　

In the second stage, the Planning Institute organized a number of cable TV networks, IPTV and Internet TV institutions to carry out tens of millions of technical experiments, which verified the rationality and feasibility of the basic theory, technical scheme, index system, survey standards, model algorithms, quality control, security and privacy protection strategies of the large sample viewing survey formed in the first stage.

　

At this stage, the experiment was highly praised by experts, and it was agreed that "it can meet the needs of ultra-large-scale, multi-source heterogeneous viewing data analysis and comprehensive evaluation of programs".

　

In the third stage, in the second half of 2018, the State Administration of Radio, Film and Television decided to carry out the construction of "Big Data System for Comprehensive Evaluation of Radio and Television Program Audience" by the Planning Institute on the basis of previous scale experiments and trial and error.

　

"From project research to experimental verification to system construction and operation, it embodies the efforts and efforts of many staff." The person in charge said.

　

As far as the industry is concerned, the completion and operation of the system has played an important role in establishing a scientific, true and effective ratings evaluation system and fundamentally solving the problem of ratings fraud.

　

Architecture: five characteristics to strengthen service management

How does the big data system for comprehensive evaluation of program ratings work?

　

The person in charge introduced that the process of viewing big data involves the collection, cleaning, warehousing, analysis and application of viewing big data. "The whole process is a bit like cooking."

　

The operation flow of the system is that the user’s viewing data is directly collected from the set-top box by operators (such as gehuayouxian) and transmitted to the viewing comprehensive evaluation big data system through a secure channel. After collecting, gathering, cleaning and converting massive data, the system carries out modeling, statistics, analysis and other work, and outputs big data viewing survey indicators.

　

There is no human intervention in the whole process. At the critical data acquisition stage, the system is equipped with a three-level verification mechanism of normative verification, integrity verification and rationality verification, which effectively prevents data from being contaminated.

　

On the whole, the innovation of big data system can be summarized into five aspects:

　

First, the sample is complete, the coverage is wide, and there are massive data sources. The system has realized the aggregation and analysis of the viewing data of 300 million cable TV, IPTV and Internet TV users nationwide, covering various viewing modes such as live broadcast, review and on-demand.

　

The second is big data, cloud computing, efficient processing and accurate home. Based on big data and cloud computing technology, the system can efficiently and timely count the super-large-scale viewing data and analyze the accurate home-to-home, which can not only reflect the viewing situation of popular programs and prime time, but also accurately capture the viewing characteristics of minority programs and marginal time.

　

The third is to prevent manipulation and pollution, and fundamentally solve the falsification of viewing. The data collection, cleaning, analysis and presentation of the system are seamlessly connected, and the whole process is automated and closed to prevent human manipulation. The system is based on massive data statistics, and the influence of individual sample data pollution on statistical results can be ignored, so the system has strong anti-pollution ability.

　

Fourth, multi-dimensional and all-round, and integrated analysis leads development. The system innovatively established an indicator system of viewing big data covering more than 80 core indicators in eight aspects. Through deep mining and timely feedback of viewing data, it guided content selection, material integration, demand combination, analysis and prediction, creation and production, changed the traditional program production mode, and effectively guided the healthy development of the industry.

　

The fifth is all-media, openness, and presuppose a new orientation in the future. The system adapts to the development of media convergence and the new changes of communication pattern and communication environment, continuously enriches the sources of TV viewing data, and will comprehensively cover different communication channels such as cable TV, satellite live broadcast, IPTV, Internet TV and network audio-visual fields, and preset the new positioning and model under the general trend of national cable TV network integration and 5G mobile application in advance.

　

Impact: promoting industry development with data

At the beginning of the trial operation of the big data system for comprehensive evaluation of program ratings, many media commented that "the problem of industry ratings was rectified in a radical way".

　

Up to now, the positive impact of the system on the industry has already appeared.

　

According to the person in charge, at present, the system has exported more than 30,000 professional data analysis reports to the central leadership, Publicity Department of the Communist Party of China, industry authorities, national television stations, etc., supporting publicity and regulation, and helping TV stations to create, produce and broadcast management, which has been affirmed by many parties.

　

Through data query and analysis or data report presentation, it provides comprehensive data support for CCTV, China Education TV, movie channels and national satellite TV channels, and becomes the main data for daily program assessment.

　

On December 17, 2019, the Program Comprehensive Evaluation Big Data Research Center officially released the viewing data to the public under the brand of "China Audio-Visual Big Data (CVB)". After the release of CVB data, it was well received by the public and applauded the SARFT’s "combination boxing" and "heavy punching" to control ratings fraud.

The first viewing data released by "China Audio-Visual Big Data (CVB)" to the public.

At the end of 2020, formulated by the State Administration of Radio and Television and approved by the National Bureau of Statistics, the "Statistical Survey System of Radio and Television Program Audience Big Data" was released, and the radio and television industry became the first industry to conduct statistical surveys of government departments in the form of big data.

　

Talking about the focus of the next step, the person in charge introduced that there are about 50 employees in the Big Data Research Center for Program Comprehensive Evaluation, who are responsible for data access and analysis, data report compilation and release, public opinion analysis, data application promotion and so on.

　

On the basis of the existing work, the Planning Institute will rely on large system resources to promote the implementation of the "Big Data System Expansion for Comprehensive Evaluation of Radio and Television Program Audience" project, improve the scale of system data aggregation, optimize the data chain mechanism, improve the quality of data throughout the life cycle, ensure the accuracy, completeness and timeliness of data collection and aggregation, and ensure the authenticity, objectivity and order of data release and application.

　

With the multi-screen viewing environment, the Planning Institute will accelerate the data access of Internet TV and Internet audio-visual websites, build a data index system for the network audio-visual field, realize the effective aggregation and analysis of network audio-visual viewing data, and give full play to the role of "China audio-visual big data".

　

A few days ago, the State Administration of Radio and Television issued the Notice on Further Strengthening the Management of Cultural Programs and Their Personnel, which clearly stated: "Look at quantitative indicators such as ratings and click-through rates scientifically and increase the promotion and application of’ China Audio-visual Big Data’."

　

Regarding the new requirements, the person in charge said, "We will continue to optimize and improve the big data system for comprehensive evaluation of program viewing, better serve publicity management, support the development of the industry, and achieve comprehensive and diversified data support for the dissemination of quality programs."

The shield machine "Jingtong" is working at the excavation construction site of Yunchao Jianhe Tunnel. (Pan Zhiwang photo)

　　Not far from the Beijing City Sub-center Station under construction, the shield machine "Jingtong", the largest diameter high-speed railway tunnel in Beijing, is excavating underground at a speed of 8 rings per day. At present, only 4.4 kilometers of Beijing tunnel section of Beijing-Tangshan intercity railway has completed 50% of the total project, and the main structure will be completed by the end of 2024, laying the foundation for opening conditions by the end of 2025.

　　Although the sparrow is small and complete, the Beijing tunnel section project integrates innovative elements such as large-diameter shield tunnel, prefabricated U-shaped groove of subgrade and fully welded double V-shaped arch bridge. The Municipal Major Project Office, together with all parties involved in the construction, will strengthen scientific and technological innovation, practice new quality productivity, and strive to turn it into a demonstration project of the city sub-center.

　　"Intelligent Shield Machine" Tunneling "Without Changing Cutters"

　　Beijing-Tangshan Intercity Railway is a fast traffic corridor from Beijing to Tangshan. The project is divided into two sections. The first section from Songliang Road to Yanjiao was opened to traffic on December 30, 2022, and the remaining Beijing Tunnel is 4.4 kilometers long. Among them, the 1.3-kilometer-long Yunchao Jianhe Tunnel is not only the last tunnel in the whole line, but also the first large-diameter shield tunnel for high-speed rail in the sub-center area of Beijing.

　　"Swing mode, go!" On April 10, I came to the shield construction site located 31 meters underground. I saw that the yellow "big" shield machine stretched out the "sucker", picked up a segment weighing three or four tons, and slowly moved and rose. When it reached the joint with the previous segment, the jack exerted force and tightened the "nut" to tightly splice the two segments together.

　　"Every 9 segments can form a ring. Now this tunnel has completed the 309 ring and completed nearly half of the workload. By October this year, the internal structure construction of the tunnel will be completed. " Wei Zhe, deputy manager of the shield of the Eighth Bid Project of Jingtang Railway of China Railway 14th Bureau, introduced the shield machine "Jingtong" independently developed by China Railway Construction. The total length of the shield machine is about 138 meters, the total weight is about 3,200 tons, and the cutter head diameter is 13.3 meters. It is the largest high-speed railway tunnel shield machine in Beijing.

　　The shield section passes through the high-density medium sand stratum, with sand layer accounting for 85% and Shi Ying content reaching 60%, which accelerates the wear of cutter head and cutter. In order to enhance the tunneling ability, the project side tailored a sharp "tooth"-a three-layer cutter for "Jingtong" to reduce the wear during tunneling and optimize the opening rate of the cutter head, so as to finally realize one-time tunneling without changing the cutter. In addition, "Jingtong" is also equipped with optical fiber continuous and hydraulic wear detection devices, which can detect tool wear in real time and adjust shield tunneling parameters in time, so it can be called "intelligent shield machine".

　　Prefabricated U-shaped groove is greatly accelerated.

　　About 300 meters to the east of the shield launching shaft is a U-shaped groove of closed subgrade, from which the train will drive out of the ground in the future.

　　Compared with the fiery scene of the shield launching shaft, the scene of the U-shaped groove is slightly "cold and cheerless", which is a hidden mystery. Of this 461-meter subgrade, 216 meters are prefabricated and assembled with U-shaped groove structure, that is, factory centralized prefabrication, which is mechanically assembled like building blocks on site to achieve safe and rapid construction. It is the first case in the national railway engineering to build a U-shaped groove with prefabricated parts, which fills the technical gap in the assembly and construction of the U-shaped structure of subgrade.

　　Wei Zhe explained that prefabricated assembly has obvious advantages. In terms of personnel, the prefabricated assembly section only needs about 15 workers a day, while the number of people in the pouring section is 4 to 5 times that of the prefabricated section. In terms of time, it takes 15 days to pour the same 18-meter U-shaped groove, and only 5 days to lay it with prefabricated parts, which greatly shortens the construction period. In addition, the amount of steel bars and concrete in precast construction is reduced by 11% and about 45%, which is low in noise and pollution, in line with the trend of green development of buildings and resource conservation and utilization.

　　All-welded steel box arch bridge echoes "Jingfan"

　　Continue to go east, 80 meters east of the U-shaped groove, and the builders are simultaneously building an arch bridge.

　　From the design, this 79.75-meter-long white arch bridge is a double V-shaped suspender structure, which is shaped like a finger and contains the meaning of "victory" and "welcome". The overall shape is like two pairs of swallows flying with their wings spread, echoing each other with the hub "Jingfan" of Beijing Sub-central Station not far away.

　　The reporter learned that the arch bridge crosses Tongji Road, the main road of the city’s sub-center, and is close to beijing-harbin railway and Tongyan Expressway. In order to reduce the impact on the current traffic, the Municipal Major Project Office took the lead in organizing the participating units to optimize the cast-in-place concrete arch bridge with full support into a fully welded steel box arch bridge after many demonstrations. In the future, the construction will be carried out by the scheme of moving horizontally first and then pushing vertically, and the process of factory processing and on-site assembly will also greatly reduce the construction time.

　　"The arch bridge has adopted a brand-new lightweight design. The dead weight of the bridge has been reduced from 4,600 tons to 700 tons, and the steel consumption per linear meter is only 11.2 tons, which can greatly save the steel consumption. This is also the first time that truss steel box arches with sparse suspenders have been used in domestic railway construction. " Liu Lei, senior project manager of the engineering department of Jingtang Company, said that the bridge will also introduce magnetic unmanned video inspection equipment for the first time, which will make the daily maintenance of the steel bridge safer, simpler and lighter, reduce its own maintenance workload and improve the intelligent level of operation and maintenance.

1905 movie network news　Directed by Five Hundred, starring Wang Qianyuan and Bao Beier, starring Wang Xun, Yanhui Wang, Qu Jingjing, Zhou You, Han Yezhou, Gai Yuexi, etc., with Liu Mintao as the special star, the crime action film "Big Man" starring Mei Ting will be released nationwide on January 11th. The advance screening of the film was held in Shandong, Beijing, Jiangsu, Guangdong, Guangxi, Hunan, Hubei, Sichuan, Chongqing and other places on Christmas Eve on December 24th. With rave reviews, the audience shouted "Nice!" "Japanese!" "Happy!"

The story is grounded. The little policeman was praised as "an ordinary big man"

　　　　

Since the advance screening of the Ministry of Public Security caused the public security police to resonate, the plot of grounding gas in the film has won praise from many audiences. Audiences have scored high marks on movie platforms such as Cat’s Eye, Taobao Film and Douban. Some netizens commented: "A true portrayal of the real society", "A very good realistic film" and "Natural and warm, not only inspirational, but also a mirror of life". It can be seen that the director 500 has brought a word-of-mouth masterpiece to the audience after the producer "White Night Chasing the Murder"!

The film not only depicts the real life of many ordinary people, but also restores the real life of grass-roots police as much as possible: Sun Dasheng, a young policeman in the film, was complained by his wife that he could not afford a school district; The unfavorable handling of the case was severely scolded by the director; It is difficult to find a criminal but encounter violent resistance to arrest, and the law enforcement process is full of difficulties. In the face of the overbearing evil forces, Sun Dasheng, a small policeman, is fearless and will never compromise, vowing to catch these criminals in the net. Some viewers said with emotion, "Sun Dasheng is an ordinary big shot." "Thanks to the people’s police for their contribution to maintaining our safety."

The audience shouted and enjoyed Christmas Eve and was awarded the "2019 Opening Year Relief Film"

Bao Beier plays the villain for the first time. In the film, he plays the evil and wealthy Zhao Tai. He and the evil groups behind him provoke the law, provoke the police, and try to buy off or even hurt the police’s families with money. "I’ll hit whoever I want!" Zhao Tai, an extremely arrogant abnormal villain, made the audience gnash their teeth. Many viewers said that "Bao Beier’s performance was too bad" and "I wanted to beat Bao Beier after watching it". Sun Dasheng, a small policeman, resolutely enforced the law, refused to be bought by money, and did what the audience wanted to do most. After his hands were covered with Chili noodles, he gave Zhao Tai a loud slap in the face, and the audience shouted "What a relief!"

It’s not as simple as slapping a face to catch all the arrogant evil forces. In the film, both the righteous and the evil launched a thrilling driving chase and a fist-to-fist melee. In the process of shooting the night car show, Wang Qianyuan personally went into battle and stripped the car with his bare hands, offering an adrenaline-boosting "car chase drama" for the audience.
