We had to wear masks... @shri's just done it. Also, my pal is actually at HKIA now... so Im asking him who made him do the test...
Everyone allowed into HK currently is a resident. PR makes no difference.
From what I understand you can quarantine at home for 2 weeks after flying into HK.
I am quite impressed with the covid precautions in UK. It feels no different to HK - other than people aren't wearing them outside, which is OK imo.
In fact I'd say it was better as I don't use public transport (back to car ownership) and supermarkets/shops are far more spacious and less busy. More space in restaurants too. Doctors is far more cautious than HK ones. Initial appointments only by phone.
I don't live in London or a big city however,
