This kind of fake accusation work in the same vein as the infamous Wuhan Diary of Fang Fang, a writer who wrote it with political motive.
It's a collection of rumors buried in half truth with the purpose of discrediting the government, such as the hospital cover up of massive death using a photo of cell phones on the floor as "evidence" sent to her by her doctor firend.
The diary is a political smudging assignment handed to her by Caixin Media, a state media with hidden anti-China agenda, any surprise? It's founded by Hu Qili who won numerous awards from the West including so called top 100 most influencial thinkers of the world, whatever that means. When things go south, she arranged for BBC to hand out award to Fang Fang at her home, a typical way to get her international exposure for protection.
Caixin Media is staffed by people including British expat anti-China troll.
Same here, such fake sexual assault accusations are organized by NGO such as me too in China. If you think it worked by white man paying her directly and her motive is financial, you're naive about politics.
