Yeah I know about her channel, but could you please link to actual "rock-solid evidence" of corruption that she unearthed? YouTube has a nice timestamp feature.
Vaguely gesturing to a dense YouTube channel is not helpful.
I don't know Chinese, but YouTube has a "sort by most popular" feature. There is the video https://www.youtube.com/watch?v=sEmQdT2ChBA, which Google translates as "Family members of victims of the Wuhan epidemic face 'political stigma' warnings and pressure from the police". It just seems to be her talking in the video, so not really "evidence" per se, but judging from the English comment it seems likely to be the video that got her in trouble.
