I don't know what Hong Kong is doing, my guess is that many professionals do not want to follow what China is doing, instead, they would like to follow what UK is doing. That's a huge difference. As I said, you cannot hide virus, hide the transmission, especially during zero-covid period, before the mild variant omicron dominated the world.

I don't know how long China can continue this zero-covid policy, that's a question, people are less worried about the virus now, I hear the same from my parents. At least it is working now. Maybe not in Hong Kong.
