Based on my research, it's been considerably easier to get flights from Korea or Taiwan to China than from HK, and I'm not sure I have the stomach to roll the dice on the land border lottery.

However, I'm still considering stopping over in HK on my way back from the US because, unlike Korea and Taiwan, I have customers (and banks) in HK I haven't visited in person for over a year. Flying down there from here for two days of meetings didn't make sense at all when HK also had the 7-day quarantine. With the new 0+3 policy in HK, it makes a little more sense, but I'd still rather wait until after I'm outside of China anyway.
