Every single person in China knows about this event. And the average Chinese person’s understanding is closer to reality about it than that of the average Westerner. Sure Chinese people’s understanding of it is overly sympathetic to the government, and they scrub internet posts about the event, but Americans have a completely cartoonish propaganda view. Listen to the reporters who were there, not random redditors with a hate boner.
Deng Xiaoping literally stepped down after this.
