You may find that they don't want you to come round even if you get across.
I've been back for 2 months and I've only seen a few members of family. More than half haven't asked to meet up. I can't even get into one cousin's house as they're too paranoid to let people in.
I'm glad I did in the summer, after 2 years of not seeing my parents and over 4 years for my siblings, it was worth it even though I ended up staying longer there and in QT hotel.
Right now the conditions for travel are terrible and who knows how it's going to be in HK once there is 1 local case, on top of the already insane guidelines. You need to be prepared to be detained for 21~44+ days... Unless it was the last chance to see someone I wouldn't go ATM.
I think the biggest uncertainty is if they reprise last year's outright ban so that you have to go for 21 days to a very small list of third countries, then do ANOTHER 21 days upon arrival in HK.
I also broke down and went to see my mother whom I had not seen for 2 years and my daughter, whom I had not seen for 3 years. Got back just in time for the omicron to hit the fan, as it were. With the US 1-day test and fly rule, hard to even get back for me anymore. My visit came in a tiny window of normality with few covid cases before delta hit the US hard.
Feel for the people who waiting until the Christmas/New Year holidays to plan their return to wherever. It's a total mess (didn't have to be but don't see the world backing down for at least a couple of months until more data comes in on omicron).
