In Shanghai, police, not trick-or-treaters and partygoers, are taking to the streets this week as the city approaches Halloween. The strengthened police force accompanies official notices prohibiting citizens from “role-playing” on Halloween, signaling the government’s paranoia over the social instability the holiday’s festivities could bring.

Videos online show police cars lining the streets of Shanghai, with some officers approaching crowds and instructing them to disperse from fenced-off areas.

A leaked notice from the Huangpu subdistrict office identified any form of Halloween costumes, but especially role-playing costumes and makeup with gore, to be prohibited in public. Police have been instructed to persuade those in costume to leave or take off offensive garments and employ more coercive measures in the event of noncompliance.

The police garrisons, protocols and general air of malaise in Shanghai find their roots in the local government’s fear of mass protest, according to Shanghai resident Ma, who declined to provide her first name out of fear of reprisal for talking to VOA.

“The Communist Party knows that 'a spark can start a prairie fire' and that many young people are now unemployed and unable to find jobs,” Ma siad. “So they have deployed a large number of police forces on Changle Road and Julu Road, probably because they are worried that some of the freethinking young people will protest against the government in a strange way on Halloween.” Ma told VOA.

Costumed people taken by police

Some youth in Shanghai have appeared to ignore the warnings, gathering in Zhongshan park and the nearby streets to celebrate the holiday early. Online videos of the scene show some people in costume being taken away by the police, while others argue with law enforcement.

At another celebration Friday night, in the Jing An district, Reuters reported that an attendee in a skeleton costume was detained by the police and escorted to an administrative building where he was asked to remove his makeup.

Wang, a Shanghai resident who declined to provide his first name for his personal security, disagreed with the sudden tightening of restrictions on Halloween celebrations in his city.

"What can wearing a unique dress do?” Wang asked. “As a normal, civilized society, this should not be a matter of concern at all. It is normal to ‘let the arts blossom’ and allow everyone to release their inner yearning for freedom. In a normal, civilized society, the police maintain the safety of the people. In our case, it's the opposite,” Wang said.

Originating in the West, Halloween has found popularity in China in recent years. This is especially the case in Shanghai, known as China’s most international city and for its relative open-mindedness.

In 2023, the city resumed the celebration of Halloween for the first time after the COVID-19 lockdowns, and some residents used this opportunity for self-expression to critique the Chinese government and political phenomena through costume. Some people dressed as Winnie the Pooh, a character that is often censored online in China given his likeness to Chinese President Xi Jinping, and others referenced past protests through covering their bodies in white paper.

Ma believes that tensions this week between Halloween celebrants and local authorities are unlikely to escalate.

"Young people are indeed rebellious, but because of the education we have received since childhood, most Chinese young people dare not, and are unlikely, to rebel,” Ma said.

“Will the authorities completely control and prohibit Halloween? I don't think they will, but they will strictly control it. There will definitely be a lot of police in more important places. If any little thing happens, they will immediately send a police car to prevent the matter from escalating," she said.

Unique opportunity for free expression

Chen Daoyin, an independent political analyst in China, told VOA that he believes that Halloween provides Chinese people with a unique opportunity for Western-style free expression.

"Most people, especially young people who dress up as characters on festivals like Halloween, have usually adopted Western culture, or at the very least know that people in Western systems have the freedom of expression,” Chen said.

“We have opinions about the current situation and the government, and can make our voices heard, but we also know that this is not allowed in the current political environment in China. Everyone knows what is going on. So they express their dissatisfaction with the authorities through dressing up as characters," he said.

Li Rongwei, executive director of the Taiwan Inspirational Association, however, told VOA that the holiday’s Western origins make it more susceptible to suppression.

"For China, Halloween is a product of the West, a typical capitalist bourgeois thing,” Li said. “Since Halloween is a foreign thing and not a product of the so-called Chinese nation or China as the CCP believes, it is, of course, a class struggle and should be slandered,” Li said.

October 27 marked the first anniversary of the death of former Chinese Premier Li Keqiang, whose unexpected passing less than a year after he left the powerful premier position, sparked online conspiracy theories about the Chinese government. The Chinese government also might fear a social disruption akin to the 2022 White Paper Movement in protest of strict pandemic regulations that was referenced at Halloween celebrations in Shanghai last year.

"Social movements always have to have a reason, and it is conceivable to use Li Keqiang as the reason,” Lai said. “This is also what the CCP fears the most. A tandem movement always has a theme. According to the perception of the CCP's top officials, it may be believed that this is a social movement planned by foreign forces.”

But Chen believes that it is an over-speculation and inaccurate to link this year’s crackdown on Halloween with Li Keqiang and the White Paper Movement and says that there will not be any kind of uprising in China without an acute inciting incident.

“It is impossible for the youth of today ... to start a movement of any kind without the impact of a big event,” he said.

"So far this year, there has been no major event that can arouse empathy and emotional expression," Chen said.
