If you are scheduling a call between Shanghai and Hanoi, the overlap window is limited to typical business hours. When it is 10 am in Shanghai it is 9 am in Hanoi — a workable window for scheduling. The latest reasonable overlap is around 5 pm in Shanghai (4 pm in Hanoi). Outside this window there is effectively no good overlap for regular office hours.
Scheduling a family call between Shanghai and Hanoi takes a little planning. Shanghai is 1 hour ahead of Hanoi, which means there's no window that feels comfortable for everyone at the same time. The most manageable option is early evening in Shanghai — around 7 pm — which puts Hanoi at 6 pm. Someone will need to stretch a little, but at least no one's setting a middle-of-the-night alarm. Weekends tend to give the most flexibility if you can agree on a time in advance.
