Yeah I’m pretty sure two things are being conflated.

The Zion Church trying to get people to drink hydrogen peroxide was based in Hong Kong and led by Leung Yat-wah. The latest evidence I can find for them existing is 2004. Seems to be some sort of offshoot of another Chinese Evangelical church based in the mainland.

Jin Mingri founded his Zion Church in 2007 as you say, seems to be based in Beijing (founded there at least). They operated 2007-2018 but was closed and banned by the govt 2018. Seems they’ve been operating as an “underground” church since then - 2018 until now is probably what is referred to by “refused to register.” Not that they could since they were banned by the govt.

Would help if people could pick original names for their right wing projects.
