Mine suddenly started working again today without adding a new card or deleting and renewing my information... Wonder if it was because everybody was freaking out about it yesterday. Anybody else have it go back to normal?

It was 400 for one year and 800 for two the last time I checked. You need a health check for two years but don't for one. I've renewed twice for the one year and didn't need a health check for either.

They asked me if I wanted a two year, so I don't think it was a problem. I just didn't want to go and pay extra for the health check.

Did not need wife's hukou (did need her temporary Kunming residence permit because she's not from Kunming), nor vaccine proof (might be a new thing), or letter of invitation as of May 2021 when I renewed. Would be interested to hear if these new rules are official now for the marriage visa/resident permit.

Also, as far as I've been told by the PSB, for marriage you can either get a one year visa without a health check or two years with one, the price for the visa is the same (double it if you want one for two years), but I renewed a one year visa and did not have to pay the additional cost of the health check.

Whoops, meant to down vote you. Ha.ha... Really don't think any of this is about foreigners. Something had to be done at some point, whether it will work remains to be seen.
