All Chinese people don't want people from other country intervene in our internal affairs. It's not because we are scared, it's because we love our country, we love our government, just like you won't like other people say your baby is ugly and hateful.
Maybe, there are many problems of Chinese government, but there is a fact, economy. Chinese government let all 1.5 billion people can eat good food, wear good clothing, support all of the 1.5 billions people electricity and water. And let people in city, rich.
We have the best high-speed rail technology in the world. Now we are leading the 5G technology. Which any other government can do all the above things?
"That country" started many many wars over these years, how many people they killed in those wars? But why I barely hear you westerns speaking out regarding to them?
Why you always want China unstable? Just because we are stronger and stronger and you feel threat?
