other anons have covered it but yeah, the chinese government is very strict about certain things. a bunch of celebrities and rich people mysteriously "disappeared" a few years ago in that they had all been previously very high profile and suddenly no one had seen or heard from them for months. turns out most of them were arrested for tax evasion. one of them was fan bingbing, although she says she was never arrested and just had to pay a fine, but she didn't star in anything from 2018-2022 because the government had deemed her subversive. there's a lot of musicians and actors/actresses that the chinese government have essentially erased all traces of their work if they'd been caught doing anything illegal.
