Do Sichuan go to Urumqi and Kashgar to be quarantined?

Sichuan is not currently a medium-high risk area, so it is not needed! But when you arrive, you have to do nucleic acid, and Xinjiang does not recognize it when it is done in other places.

No, only people in middle-risk cities with outbreaks are quarantined

If you haven't been to a risk area recently, you won't be quarantined. You just need to do nucleic acid when you land.

No, but nucleic acid will be required to be done at the destination
