I know what happened in 1989, many people have paid a price for their actions. because of the disparity in power, its silly to reach the goal by bleeding. If they were successful at the time, China would no longer be ruled by the Chinese. Maybe China will be a multi-party ruling country in the future, but definitely not now. However, I think there is nothing wrong with the policies of Xinjiang and Tibet. Do you want your country to split? I dont understand the human organ trafficking incident in Xinjiang, so I cant comment it. If you can't stand the CCP at the moment, immigration is the best way. Good luck.
