Sounds like your typical hilariously false Falun Gong horror story.
It's a very popular way for culty diaspora to cope with being rejected by their families, basically identical to QAnon.
I know some Christians in NZ who are from mainland China. They have the same stories.
My friend's wife's family completely disappeared because they said something bad about the local government on WeChat. Their house was empty when she went to check up on them (after COVID). Neighbors said the police came in and they haven't seen them since. She now blames herself for not bringing them to Canada.
The reason the surveys are so high is because they fear it's a trap. If someone asks you if you like the government, your answer better be an outstanding yes.
