Update, there was a different confirmed case from someone coming to Jinghong. You can follow YNTV2都市条形码 on wechat for news updates in Yunnan, it's in Chinese but wechat has a translation function. Seeing a lot more people wearing masks outside as well as checkpoints at markets and neighborhoods. Everybody keep safe, wear a mask and get vaccinated. Any chance GoKunming can do an official article or give updates in English?

Apparently there is a positive case from a student in Anning who recently went to Jinghong. Details are still coming out, but I'd guess that's the reason. It's also in the border area so that may have something to do with it.

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.
