Recently, whether fans have aroused conflicts with their peers by reporting the fan fiction database website-AO3, or fans of the draft variety "Creation Camp 2020" and fans of the same type "Youth has You 2" have begun to "break their heads".（battle）The "rice circle" caused quite a stir on the Internet, and many idols were forced to "go out of the circle". However, why do fans always have fierce contradictions? Can fan culture be compatible with popular culture? Where did the original "rice circle" culture come from?

In order to answer a series of questions about "rice circle culture", Huayi Brothers Research Institute deeply explored the fan culture. This paper will focus on the origin, development process and characteristics of fan culture, and deeply analyze the circle and structure of entertainment rice circle culture in the mainland.

Origin: Influenced by the cultural circles of East Asia and Europe and America, China’s "fan culture" has taken shape.

The worship and pursuit of idols are rooted in human nature, but the formation of fan culture is not only based on feelings, but also influenced by social, economic and cultural aspects. Internationally, the prevalence of consumerism in the 1980s provided a fertile ground for the outbreak of the fan community, which also attracted academic attention to this cultural phenomenon. From text deconstruction and reconstruction, to field and social class, to emotional pursuit and psychoanalysis, the relationship between fan culture and many key fields has gradually become clear.Numerous studies of fan culture in the context of mass culture, media communication and economic power show the integration of fan culture and the complexity of its internal mechanism.

Due to the different basic economic environment and media preference, foreign fan studies can not fully explain the current situation of domestic fan culture. However, it is undeniable that China’s fan culture was really influenced by the East Asian cultural circle in its early days. Even today, China’s fan culture still contains a series of fan behaviors such as Japanese "house" culture and Korean idol culture, such as "calling", "playing the list" and "supporting". With the acceleration of internationalization, the frequency of the word "European and American circle" in fan culture has gradually increased, and the new fan culture has impacted and changed the original domestic fan culture. AO3（Archive of Our Own）And other more open fan creation websites have therefore entered the field of vision of domestic fans and become a gathering place for some domestic fans.

Change: from "groupies" to the establishment of "rice circle"

China’s modern fan culture took shape in the middle and late 20th century. Teresa Teng, Little Tiger, Chow Yun Fat and other Hong Kong and Taiwan stars had a large number of fans, and the appearance of Cui Jian and other rock stars also met the spiritual needs of young people at that time. However, during this period, fans’ idolatry was confined to the mechanism of one-way communication, and fans’ behavior was mainly to receive information. The term "groupie" also came into people’s field of vision.

In 2005, Super Girl’s program exploded, driving fans to become a unique social group and cultural phenomenon into the mainstream. Groups such as "corn", "bean jelly" and "box lunch" have entered people’s field of vision with an unprecedented speed and high-profile posture, breaking the traditional impression of groupies in the past. They not only went to the show site to hold up light signs and shout uniform slogans to cheer for the players they supported, but also expressed their attitudes through SMS voting and even called for more people to vote through a large number of promotional materials. Not only did it help your favorite players to "get through the customs" round after round, but it also made the talent show a carnival of "participation by the whole people".①

Since then,With the development of new media environment, fan culture has also undergone a new transformation: the original one-way communication between fans and idols has changed into two-way communication, and virtual communities have improved the scale and organization of fan groups.Weibo has become a gathering place of fan culture because it provides a platform for direct communication between fans and idols, which satisfies the imagination that fans can contact idol life and have direct dialogue with idols. Even to some extent, this kind of imagination is built to satisfy the psychology of fans.Pseudo interactive relationship, and thus produced some discordant sounds. On the other hand, the network has further increased the scale of the fan base, becoming a so-called "rice circle" and creating its own discourse system and power system. Fans can quickly locate their peers with the same hobbies through the internet, and fan activities are more organized through the internet. At the same time, the emergence of professional websites and apps in idolize has further promoted the commercialization of fan culture and spawned more diverse fan activities.

Driven by the trend of consumer culture, the society has changed from production-oriented to consumption-oriented, and the fan economy has flourished with the popularization of fan culture.Fans are not only the main body of culture, but also the main body of economy, playing a huge role in the consumer society.Therefore, the emergence of "professional fans" is logical. Professional fans either earn money through fan activities, or cooperate with brokerage companies and cultural companies to operate fans to get paid. While the commercial value of fans is improving, the guidance of relatively negative economic demand to excessive behavior is also emerging at this time.

From the changes of fan culture, it is not difficult to find that the balance of power between fans and idols is unconsciously tilted. With the advent of the era of "star-making" fans, "flow" has become the lifeblood of grasping the idol cause, and the power of fans has been further enhanced, even reversing beyond the idol itself.The industrialization of idols has caused a sharp increase in the number of idols, an increase in the mobility of fans, a change in the buyer’s market position, and fans have more right to speak and decide.However, the strong capital in the layout of big entertainment has come to an end, and a new party has been added to the idol-fan system, and the game is more complicated and intense. The "rice circle" of social network platform has expanded the application field of fan culture, and more and more people have noticed the strong emotional connection and high user viscosity of fan culture. As a unique community structure, fan culture is highly involved in today’s social structure and activities.

Ecological characteristics of Chinese vermicelli

Refined fan operation: strict organization

Under the great influence of the fan economy, the fan ecology of fans is no longer an initial "atomic" individual activity, but an organized and distributed collective activity. Fan operation is no longer an industry secret, as long as you mix for a while, "solid powder"(Maintain existing fans by communicating with them more), "powder abuse"(Stimulate fans’ desire for protection by shaping the image of idols being bullied, so as to strengthen emotional ties), "purification"(Cut off the relationship between the two idols who used to be "cp" in film and television works, and convert the double fans into single fans, that is, "only fans")"explosion-proof"(prevent the same type of idol from exploding)Waiting for the routine, even if it is "loose powder"(Fans who have not participated in any support meetings and fan groups)And I know it.

The refinement and specialization of fan operation is inevitable. First, spontaneous fan behavior is prone to irregular behavior because of emotional and irregular behavior, which has a negative impact on idols, so it needs correct guidance; Second, the subjects associated with the idol industry are becoming more and more diverse, and the cooperation between brokerage companies, content production companies, brands and video platforms requires the guidance of professional teams to maximize benefits; Third, the internal attributes of fans are different, and their preferences and activities are different. Professional teams can allocate resources more reasonably to meet the psychological needs of all parties.

In terms of organizational structure, the management of all fans consists of three parts, namely, the internal class management of fan organizations, the fan management with the brokerage company as the core and the commercial value of idols as the guide, and the professional fan companies that focus on the operation of fans as a whole rather than a specific idol fan group, such as Super Star Rice Ball.

Every fan activity, the brokerage company guides the "big powder"(Opinion leaders among fans), "job powder" and the management of the support club, disclose the information and the purpose of the support activities in advance, and these fans will pass the information to the fan group. The activities within the fan group are carried out in the form of "multi-point gathering", with "big fans", individual stations and support clubs in different regions as the multi-point core, and ordinary fans are gathered for large-scale support. In this process, professional fan companies not only play an auxiliary role, but also may be the purpose of some kind of fan activities, such as learning about idol dynamics through fan apps or playing on fan apps.

"Heterotopia" in Rice Circles: Community and Exclusion

heterotopias co., ltd creativity | plan | dissemination（heterotopias）It’s Foucault.（Michel Foucault）A kind of observation of society proposed is different from a fictional utopia. Heterotopia is connected with the real place, but it is different from the ordinary cultural space.The virtual space "rice circle" formed by fan culture conforms to the characteristics of "different countries";The tendency of the population, its role in society, its juxtaposition in space, its combination with the fragments of time, and its opening and closing system.

"Fanhuan" is a collection of groups, which has crossed the barriers of time and space, has rules and thinking different from the actual rules, and has a certain threshold to enter Fanhuan.

Promoting fans from individuals to relatively stable communities is a variety of fan activities in the multimedia channel environment. Collective labor, such as hitting the list and rushing sales, has stimulated the emotional connection of the group, such as successfully helping their idols get the first place in the list, which has increased the individual’s recognition of the community. In order to prevent the loss of fans, fan activities are usually regular or frequent. In this case, the community can maintain relative stability. At the same time, more and more communication channels, including Weibo fan groups, WeChat groups and QQ groups, provide the foundation for closer and personal contact, and the doping of personal emotional contact increases the stickiness of the community.

As an independent group, "rice circle" has its own independent discourse system and rules, and its representation is often called "rice circle language" and "rice circle thinking".Abbreviations often seen in Weibo are typical of rice circle language: behind the abbreviations of people’s names is the logic of rice circle to prevent fans from searching the square for comments and attacks; y1s1(there is a saying)、dw(poison only means extreme powder only)、bp(Bai Piao, a fan who doesn’t spend money on idols)These words, which can be understood by internal members and confused by non-rice circle people, not only establish a barrier between rice circle and the outside, but also consolidate the sense of group identity within the community.

However, the "alien state" of rice circles is in contact with the mainstream culture, and it is not completely independent, so there is also a conflict between the unique thinking and universal values of rice circles.In the context of rice circles, "powder is black" and "comparison is stepping on" is somewhat mismatched under the dualistic popular culture that does not agree with "black is white". However, the rice circle culture really affects the language form of Chinese network and the thinking logic behind it, so it is often criticized.

Fans are extremely exclusive, which may be due to the fierce competition in the idol industry.At present, among the top idols, basically every one has had a fierce fan struggle with several others. The reasons are nothing more than fighting for the first place, for endorsement resources, and for traffic. For example, because of similar fame paths.(Acted in a beautiful drama, and became popular because of his outstanding acting skills)And similar images, fans of Sean Xiao and Zhu Yilong once attacked each other. Even because of the different attributes of fans, "only powder"(fans who only like one idol)"Tuanfen"(Like a fan of an idol group), "cp powder"(fans who like a real couple or an imaginary couple)There are also conflicts between them. Idol groups debuting in the recent draft, such as Rocket Girl and NINE PERCENT, often have conflicts with individual fans because of different interests.

▲NINE PERCENT　

The exclusiveness of fan culture is not only reflected in external disputes, but also caused by the strict institutional class at home.Although only gathered for the same hobby.Interest groupHowever, there is a hierarchical difference in the right to speak among fans. In fan organizations, it is common for the management to hold a group. When the upper level agrees, fans with different views will be kicked out of the support club or support group to ensure the "harmony" of the organization. "big powder"(opinion leaders among fans, often UGC creators, paragraph players or professional fans)Our views affect the wind direction of the whole fan community. Once there is an abnormal sound, it is either ignored because the sound volume is too small or destroyed because of the attack of "big fans". Although rice circles have begun to realize the negative impact of "big powder", it is unrealistic to put an end to the impact of "big powder" because of its strong functionality in the current fan community structure.

Conclusion:

With the development of Internet, the development of entertainment industry and the changes in the way stars debut, China’s fan organizations have evolved from the "groupie" period to the "rice circle" era, and the rigor and organization of this organization have also been significantly enhanced, and its influence has gradually expanded, becoming a large group organization that cannot be ignored in today’s society.

　　Since the national park system was piloted in 2019, Hainan has made great efforts to build a new model of intelligent ecological management and protection. Hainan Rainforest National Park Administration has built a provincial-level smart management center and a smart rainforest big data center platform, and carried out "electronic fence" construction pilot projects in Bawangling, Diaoluoshan and Wuzhishan, and started the "sky-land" integrated monitoring system project of Hainan Rainforest National Park, exploring the construction of a four-in-one tropical rainforest monitoring system of "forest dynamic monitoring sample plot+satellite sample plot+random sample plot+kilometer grid sample plot".

　　On the monitoring screen of Jianfengling Branch of Hainan Tropical Rainforest National Park Administration, the video can be switched to multi-angle high-definition images at any time, and live broadcast can be realized by connecting with the camera installed in the rainforest.

　　The forest coverage rate of Jianfengling area is over 97%, which is rich in biological resources and is one of the hot spots of biodiversity in the world. "Through ‘ Electronic fence ’ And multi-functional monitoring system, we have greatly reduced the number of people entering the mountains and found many species that have not been seen for a long time. " Yang Shibin, deputy director of Jianfengling Branch of Hainan Tropical Rainforest National Park Administration, said.

　　In addition to ecological protection and resource monitoring, scientific and technological means are also applied to the daily patrol and maintenance of Hainan tropical rain forest.

" Wang Nan, deputy director of Hainan Rainforest National Park Administration, said, "In addition, a series of other scientific and technological means are also helping the effective management and protection of Hainan Rainforest."

The green "safety exit" indicator light in public places is an important sign to deal with unexpected accidents. Recently, some citizens reported to the Beijing News that some of the "safety exit" indicator lights in the east underground passage of Xidan intersection and Xidan subway station in Xicheng District were out of order and there were potential safety hazards.

The Beijing News reporter visited Xidan, Tianqiao, Puhuangyu, Shilihe, Dawang Road and other subway stations, and found that the "safety exit" indicator light was not lit and the indicator signs were damaged in many stations.

The failure of some indicator lights in the underground passage of Xidan intersection was reflected and repaired on the same day.

On the morning of August 16, the reporter visited the east underground passage of Xidan intersection mentioned by the public. There are 18 "safety exit" indicators on the walls on both sides of the passage at intervals of about 8 meters. The fault indicators reflected by the citizens were all repaired at this time. According to the staff, all the indicator lights in the channel have just been overhauled recently, and there is a special person to overhaul the channel equipment once a month. However, in the underground passage on the west side of Xidan intersection, although there are security guards standing guard, there is no "safety exit" indicator or logo.

The east and west passages of Xidan intersection lead to the two entrances and exits of the subway station respectively. The reporter entered Xidan Station of Metro Line 1 along the passage and checked the indicator light along five lines. At Xidan Station, there are indicator lights or signs beside the elevators at each entrance and exit, on the walls of underground passages, and on the columns near the trains. However, at least four indicators are not lit, and many indicators are low in brightness or only partially lit.

The reporter reported the situation to the person in charge of the subway station as a citizen, and the other party recorded it and promised to contact the maintenance personnel to check it on the same day.

In view of the low brightness of some indicator lights, the person in charge said that Metro Line 1 is the first subway in China. Due to the early construction time, some equipment along the station is not as advanced as the newly built subway station. "The low brightness of some indicator lights is not a fault, because they are not used for lighting. When there is an accident and power failure, the surrounding light becomes dim, and then the indicator lights can be seen clearly." The person in charge said that the "safety exit" sign posted on the wall has a fluorescent function, which absorbs light at ordinary times and can also emit light in the dark.

At two o’clock in the afternoon, the reporter came to Xidan subway station again and found that the workers with the words "Beijing Metro Electromechanical" printed on their clothes were leaving with ladders on their backs. The reporter noticed that the indicator light that failed in the morning has been repaired.

Shilihe and other subway stations are patrolled every day, but the indicator light is still faulty.

On August 17th, the reporter visited Dawanglu Station on Line 1, Puhuangyu Station and Shilihe Station on Line 14, and Tianqiao Station on Line 8. Compared with Line 1, Line 14 and Line 8 are newly opened subway lines in recent years, and the indicator lights in the stations along the lines are brighter and more densely distributed. However, these sites also have indicator failures and broken signs.

At noon that day, the reporter called Beijing Jinggang Metro Co., Ltd., which belongs to Line 14 subway, and the service hotline of Beijing Metro Operation Co., Ltd., which belongs to Line 1, as a citizen to feedback the fault. In the afternoon, the staff of Puhuangyu Station and Shilihe Station on Line 14 called back and said that the lights and signs in the stations had been thoroughly inspected and would be replaced in the near future.

According to the staff of Puhuangyu Station, after receiving the report, three indicator lights were found to be faulty and two indicator signs were damaged. The maintenance personnel will complete the maintenance in the afternoon. The person in charge of Shilihe River detected that two indicator lights were faulty and four indicator signs were damaged. The indicator signs will be replaced in the afternoon and the indicator lights will be replaced in the near future.

The person in charge of all the sites visited by the reporter said that there are special personnel in the station to overhaul all the equipment every month, and there are also people on duty to patrol in turn every day. Why was the indicator light problem not discovered in time? A person in charge said that sometimes there is a large passenger flow during peak hours, and the patrol personnel temporarily handle other emergencies, which may lead to the interruption of the patrol. Next, the patrol will be strengthened.

Mr. Wu, a citizen, believes that when an accident occurs, the public can evacuate in time according to the route indicated by the "safety exit" indicator light. If the indicator light cannot be repaired in time, it may lead to an accident. "It is not difficult to repair it in time, and it doesn’t cost much. The key is whether anyone notices it." Mr. Wu said that especially in some prosperous business districts, the daily passenger flow is large, and more attention should be paid to the safety of related facilities.

At noon on August 19, the reporter came to Shilihe Station and Puhuangyu Station on Line 14 again. The failed indicator light has been repaired and the broken indicator has been replaced.

Tips

If you find the indicator light and other problems, you can contact the subway station staff or call the hotline.

In several subway stations, the reporter did not find the public information of the subway service hotline. Some passengers said that if a problem is found, I don’t know what department to call and what to call to reflect the situation.

In this regard, most subway staff said that they could contact the staff in the station directly, but some people on duty did not know what hotline to call.

The reporter learned that the Beijing subway line belongs to the jurisdiction of different operating companies. Among them, there are 16 operating lines under the jurisdiction of Beijing Metro Operation Co., Ltd., including Line 1, Line 2, Line 5, Line 6, Line 7, Line 8, Line 9, Line 10, Line 13, Line 15, Batong Line, Airport Line, Fangshan Line, changping line, Yizhuang Line and S1 Line. The company’s service hotline is 010-96165.

Beijing Jinggang Metro Co., Ltd. is responsible for the subway operation of Line 4, Line 16, Line 14 and Line Daxing, and its service hotline is 86-010-63988622.

Yanfang Line is managed by Beijing Rail Transit Operation Management Co., Ltd., and the passenger service hotline is 010-87837266.

　　[car home Technology] I don’t know if everyone in front of the screen knows anything about the 100,000-class pure electric compact car. As far as the author is concerned, the competition of this class of cars is actually quite fierce. On the one hand, it is a price war, on the other hand, it is repeatedly involved in design, safety and configuration. In this class of cars, (|) successfully circled the powder with its retro and beautiful shape. Of course, we don’t talk about design today, but look at the scientific and technological strength behind this boutique car through actual disassembly.

● Five-ring body frame

　　The length, width and height of Wuling Binguo are 3950*1708*1580mm respectively, and the wheelbase is 2560mm. Thanks to its front-drive pure electric platform technology, the cabin space utilization can be maximized.

　　For small cars, consumers are not only concerned about the performance of their cabin space, but also extremely concerned about their safety. Binguo adopts a five-ring car body frame structure, which can increase the rigidity of the car body and improve NVH performance, and at the same time, it can quickly transfer collision energy when a collision occurs, reduce the intrusion of the passenger compartment and protect the safety of the passengers.

　　The A-pillar, B-pillar and sill beam constitute the thermoformed steel door ring, which can bear higher pressure and improve the torsional stiffness and safety of the car body. At the same time, the steel door ring of hot car can also improve the sealing performance and torsional stiffness of the car body, improve NVH performance and enhance ride comfort.

　　The energy-absorbing box can reduce the maintenance cost of low-speed (20-30km/h) impact, because the energy-absorbing function of the energy-absorbing box can avoid the damage of the longitudinal beam, and the damaged energy-absorbing box can be replaced separately.

　　According to official data, compared with the design of only the front finger beam and the front longitudinal beam, the triple frontal collision-resistant energy-absorbing structure design of Binguo can achieve a 15% improvement in energy absorption efficiency.

　　There is also a steel anti-collision beam at the rear of Binguo, but there is no energy-absorbing box between it and the body. Even so, the existence of the anti-collision beam can disperse the impact energy of the rear collision, thus reducing the damage degree of the rear collision accident to the vehicle.

● Robust chassis

　　Binguo adopts the suspension combination of front McPherson and rear torsion beam, which is common at the same level. Simple structure, durable leather and low manufacturing cost are a major feature of this suspension form.

　　Compared with the open beam, the closed torsion beam with variable cross-section improves the stiffness of the torsion beam by 41% and the bearing capacity accordingly, thus reducing the vibration and improving the ride comfort.

　　According to the manufacturer’s introduction, Bingo’s chassis adjustment style is tough, that is, to ensure ride comfort on the basis of achieving good support of the car body. Therefore, bingo will be more stable when driving at high speed, giving people more sense of security, and emergency lane-changing vehicles can also provide good support. Binguo 410km Linxi Exclusive Edition uses a brand-new motor with better performance, and its top speed can reach 130km/h, which is higher than that of other models with 100km/h and 120km/h, so it is quite necessary to match a robust chassis.

　　Compared with the 175 and 165 tire widths commonly used in the same class, the wider tread of Bingo standard tires is beneficial to improve tire grip, make the vehicle run more stably, and ensure sufficient braking performance.

　　In addition to making great efforts to filter the vibration of the chassis to improve NVH performance, Bingo also made a fuss about the details such as the sealing and sound insulation measures of the passenger compartment. Both the front and rear side doors of Binguo have two complete sealing strips to ensure the tightness of the passenger compartment and avoid the introduction of environmental noise and wind noise into the car. At the same time, the sound-absorbing cotton of the front and rear outer wheel covers of Bingo is made of non-woven fabric +PP+PET+ non-woven fabric, which can effectively absorb the tire noise and the noise generated when the suspension system works.

● Water-cooled flat wire motor and refined battery

　　Binguo 410km Lingxi exclusive edition adopts water-cooled flat-wire permanent magnet synchronous motor, which is a three-in-one design and integrates motor, electronic control and differential.

　　Compared with the round wire motor, the slot fullness of the flat wire motor is increased by 20%, the contact area between the flat wires is larger, the heat conduction is better, and the heat dissipation capacity is stronger. The power density of the flat wire motor is increased by 0.8kW/kg, and the high efficiency range is expanded by 11%, thus making the maximum efficiency of the motor more than 96%.

　　We can see that there is a cooling water jacket on the stator shell of the motor, and the cooling liquid will circulate in the water jacket, taking away the heat generated when the motor works, and improving the continuous high power output performance and durability of the motor.

　　Wuling’s refined battery should be familiar to all of you. I introduced this battery in detail in the technical article of Wuling Starlight (click to view).

　　The battery core of Shenlian battery can not catch fire or explode in the acupuncture test; In the shallow needling test (the steel needle penetrates 1/3 of the battery thickness), the battery can still discharge normally; When the battery cell is extruded and deformed by external force up to 40%, it can not catch fire or explode. The safety performance at the cell level is quite eye-catching, which is also the key factor for the high safety of Bingo battery system.

　　At the level of battery pack, Shenlian battery adopts a structure called MUST, that is, Multifunctional Unitized Structure Technology, a multifunctional integrated battery pack structure technology. The biggest feature of this structure is that the cells are put into the reinforced frame and then installed into the battery pack. This reinforced frame can improve the structural strength of the battery pack by 60%.

　　Battery packs have suffered a lot in the laboratory, and it is common to go to the mountains and go to sea. The whole package of Shenlian battery has been tested by temperature change test, water immersion test, high temperature acupuncture test, vibration test, bottom dynamic impact test and charge-discharge test.

More exciting videos are all on the car home video platform.
"Needle Punching Test of Shenlian Battery Core"

　　Like mainstream electric vehicles on the market, Bingo’s BMS battery management system also supports Che Yun Intelligent Collaboration. In addition to real-time monitoring of battery status at the vehicle end, all-weather and life-cycle second-level safety inspection will also be carried out in the cloud. When the system detects battery collision, stabbing or overheating, it will actively remind the driver to prevent problems before they happen.

　　According to the manufacturer, this can reduce the maintenance cost by 90%. At the same time, Wuling has also strengthened the training of battery maintenance in the 4S after-sales service system. I believe that in time, its after-sales service outlets will be fully equipped with power battery maintenance capabilities. Compared with the power battery specialized service that can be seen in the market now, it is obvious that the official after-sales service can reassure consumers.

　　In this regard, I also asked the engineer at the dismantling site whether there will be batteries in the form of direct cooling or water cooling with refrigerant installed on Bingo. The engineer’s reply is vague and only means "on the road". Perhaps in the future, Bingo with more powerful electric drive system will use direct cooling or liquid cooling battery system with active temperature control function, which is worth looking forward to.

● Full text summary:

　　Wuling Binguo, as a pure electric small car, has done its homework in terms of cabin space utilization and safety, completely dispelling consumers’ concerns about small space and insecurity of small cars. At the same time, the affordable price of 59,800-88,800 yuan, combined with its fashionable and beautiful shape, is a good choice for buying food scooters in the near future.
