A liar always covers their lies with more lies. In the case of totalitarian states such as the PRC, it's called propaganda, changing the narrative and rewriting history books with alternative history, aka fiction.

The Nixon administration took another approach in the US: they started the war on drugs to discredit and silence the anti war hippie movement. This worked fine for those in power, but had and still has a lot of victims. Chairman Xi would have probably pulled a Tiananmen.
