This is probably more for the "I hate" thread but I fucking despise QR codes. Eeeeevrything here involves QR codes. Covid-related, we have to (or used to anyway, not so much now) show green codes to be allowed into buildings, which is fine in your own city where you're all set up. But every province has their own code, and they're not connected or on the same platform. I was flying to another province recently and they asked me for my code, so I showed the code of where I live and was told no, it needs to be the other code - which you can only get by entering tons of details including the subdistrict of the hotel I was staying in (impossible to find, so they just said "put whatever", negating the point of the whole thing). Anyway, as obviously I was still 3 hours flight away from Hainan, I hadn't come into contact with anyone there, sick or otherwise, so I got a green code. Some provinces don't actually allow foreigners to register for codes so everyone just shows a screenshot of a code they got from a mate. It's all really stupid and a charade of "safety".
