Thanks - but how can I renew my student visa without leaving China? My school said I must return to UK (I am UK citizen) to apply for a new visa. (Nothing on British embassy Beijing website)

Looks like a new QR code has appeared at all metros (and bus?) to be scanned leading to a health check form to complete. I tried filling it in in English but was unsuccessful, so asked my friend to fill it out in Chinese and it worked. Long queues at entrances whilst filling it out. Can anyone explain why they are introducing new restrictions/registration/monitoring now the virus issue is fading away and everything is getting back to normal?

Does anyone know what the new policy is towards visa renewal AFTER the automatic two month extension? I have been told conflicting things by my language school and the PSD. It appears that all foreigners will have to leave China to apply for a new visa to return to China, but the visa application centres in UK, for example, are all closed! Is this an attempt to drive all foreigners out of China over the next twelve months or can we renew visas inside China (as happened before the new virus rules)?

In answer to Faohi, my current experience in the quarantine hotel is that the food is provided (we have paid 60/person/day). No choice. Three meals. Breakfast mostly spicy noodles so I cannot eat it. Lunch and dinner are ok - boiled rice, veg and some meat. some spice, but not all, so safe to eat. I brought some other food with me to top up so I am ok. I have not tried asking for non-spicy. Also not asked for outside delivery as sufficient provided. Also two bottles of water each included each day.

Arrived from Chiang Mai Sat 14 March. My experience on the flight and arrival at Kunming similar to above. I was separated from my Chinese girlfriend and taken off the plane first with another foreigner and some other Chinese people. I kept in touch with my gf via wechat so realised that they were waiting for the results of our tests before releasing the rest of the passengers. Kunming airport empty. Only international flights were from Vientiane and Luang Prabang in Laos, Sikhanouville Cambodia and Rangoon Myanamar. We were cleared to return on the metro no problem - just 3 hour delay. Flight landed 5pm, out at 8pm. BUT my Xiaoqu insisted on 14 day home quarantine and gave us a thermometer to check twice per day. THEN on 18th morning we got a call to say we had to go to the quatrantine hotel that evening! Then a few hours later, we got a message saying we didn't have to go after all. Then late in the evning we got another call saying we did have to go that evening. I got angry with them (in Chinese) and eventually agreed on going on 19th at 2pm. Bizarrely, we were told to make our own way across the city to the hotel!!! We are now in the hotel for ten nights (they appear to agree that our self-isolation for 5 nights should count towards the 14 days, but because their checkout time is 12 noon and we arrived Kunming airport at 5pm we have to stay another day. Now in isolation in the quarantine hotel - 140rmb for the room (both me and gf) plus 60 each for food plus 200 deposit.
They did a swab test of the back of our throats soon after arrival, but otherwise two temp checks a day is the only visits, so far......So it looks like they are rounding up people who arrived in Kunming in the 14 days prior to the rules changing on 16-18 and putting them in quarantine AFTER they have already been in the city for many days!!! Bizarre!!! Anybody else have the same experience?
