These are the reasons that I think are reasonable - After merging with Ha Tay, Hanoi (capital) is the largest province in Vietnam - +7:00 (North Vietnam and All Vietnam since 1975) timezone has been the longest unified timezone ever, compared to Asia/Saigon, Asia/Ho_Chi_Minh (modified many times) I would like to suggest adding a timezone for Hanoi or changing the name from Asia/Ho_Chi_Minh to Asia/Hanoi as the official timezone for Vietnam. Having the same article should be considered https://tz.iana.narkive.com/foJrvdQn/tz-patch-tzdata-asia-ha-noi-add-new-tim...
Ho Chi Minh City and Hanoi are two separate big economic regions of Vietnam, just like Nick Phake said, creating two separate time zone names for the two regions is reasonable. You have also said that using Shanghai's time zone represents China, but then still creates timezones for Beijing.
If you see any timezone locations for Beijing, please talk to your software vendor about adding the locations you desire, as Beijing is not in the tzdb. Whether the locations you desire map internally to Asia/Bangkok, Asia/Ho_Chi_Minh, or Asia/Saigon will make no difference to the time displayed on your system. If you need correct times prior to 1970, please consider submitting patches referencing your research sources against the appropriate backzones, possibly being prepared to maintain your own backzones if not accepted in tzdb. This may be easier if you create your own fork of the experimental github repo and test making your patches against that, building tzdb files matching your requirements, possibly including backzones. -- Take care.
