It depends on the content of the criticism
If you mean something like FJB, I'm sorry, it's not allowed in China
China has laws to stop such public attacks on individuals and the government. Any insulting or ideological attacks are prohibited. Of course, this does not mean that you will be arrested after making certain public remarks, but your remarks will usually be deleted. It's the same as our remarks being deleted on Youtbe or X.
If your criticism is directed at a specific event, then it's okay.
Chinese people or the Chinese government are pragmatic. They don't like to waste time on political slogans and empty theoretical struggles.
If what you want to express is: the government is terrible, we need a better mayor to solve the various serious problems in the city!
Such criticism will be regarded as stupid in China, no one will pay attention to you, and everyone will think you are an idiot.
They welcome such criticism:
The traffic is terrible, there is always a serious congestion every morning at 5 kilometers on Highway 3, you must do something!
The garbage problem is terrible, the creeks in Pearl Park and Green River Park are full of garbage, what is the city cleaning department doing?
My house is threatened by noise, and a group of elderly people gather in the park downstairs every morning. It makes it impossible for me to rest, and you must solve all this.
Very good, if your criticism is like this. Then you have mastered the trick of criticizing the Chinese government.
This kind of criticism will have two dimensions of effect
1. Criticism itself
The government will have a specialist to evaluate your criticism (it may also be with the help of AI), your criticism will be classified, the jurisdiction will be determined, and it will be pushed to the corresponding responsible department.
The department that receives the criticism will investigate the situation you criticized and reply to you about their investigation and handling. And ask you to make a final evaluation of the case.
If you are not satisfied, you can appeal to their superior department again.
2. Statistical significance
When citizens have a lot of criticism around the same issue, such criticism will be upgraded to the perspective of "global problems". This may mean that a department or an official has not performed his duties correctly, resulting in "bulk" dissatisfaction. Such problems are often given priority and trigger performance appraisals of officials. Severe cases may even trigger investigations and accountability of officials.
In fact, the Chinese government has set up many channels to accept people's criticism, such as reception offices, emails, and hotlines. The most popular way is to submit your criticism through the Internet.
When I visited Shanghai, one of my female colleagues showed me a process of criticizing the government.
A new viaduct was built under the apartment building where she lived. This viaduct was to solve the traffic congestion on that road (nearby residents have been complaining for a long time)
But after the viaduct was built, the speed of vehicles increased significantly.
This brought more serious road noise, affecting the rest of the residents in the adjacent apartment building.
She was one of them, and she submitted her complaint about the matter through the website of the Mayor's Mailbox of the Shanghai Municipal Government.
Three days later, her complaint was submitted to the Minhang District Traffic Management Bureau of Shanghai.
The Minhang District Traffic Management Bureau responded to the criticism two days later. It said that the construction of this viaduct had passed the environmental protection approval of the municipal government and was legal. Regarding the noise issue, they will be handed over to the Environmental Protection Bureau.
The Minhang District Environmental Protection Bureau replied two days later that they would send a commissioner to the vicinity of the viaduct to measure the noise. A week later, the Environmental Protection Bureau responded to the message: the noise measurement has been completed, and they believe that the noise at night is within the legal range. They hope that she can understand this matter and make a closure evaluation on this matter.
My female colleague obviously disagreed with the government's explanation, so she called on her neighbors to criticize on the website, and they submitted the same opinions. About a week later, this opinion was raised to a higher level, and the Shanghai Municipal Government Environmental Protection Bureau intervened. Two weeks later, representatives of the residents of the apartment building were summoned to hold a hearing.
Two months later, a tunnel-shaped soundproof wall was built on the viaduct to completely isolate the traffic noise of the viaduct.
This criticism of the Shanghai Municipal Government was closed after several months.
This is a typical case of Chinese citizens criticizing the government and waiting for the government to respond to the criticism.
All the contents of these documents can be checked on the government website and made public to everyone.
