Why people convert Ho Chi Minh to Hong Kong time

Scheduling a call from Ho Chi Minh to Hong Kong: a 10:00 AM start in Ho Chi Minh lands at 11:00 AM in Hong Kong, so you can confirm the slot without doing the arithmetic yourself.
Finding shared working hours: both Ho Chi Minh and Hong Kong are inside the 9-to-5 working day between 9:00 AM and 4:00 PM ICT time (10:00 AM–5:00 PM HKT). That is roughly 7 hours of usable overlap.
Coordinating a Ho Chi Minh-based team with Hong Kong contacts: quoting times in the other side's local clock — not your own — removes the single biggest source of missed meetings.

Always state the zone abbreviation, not just the hour. "3:00 PM ICT" is unambiguous; "3 PM" across a +1h gap is not.
Block 9:00 AM–4:00 PM ICT as the recurring meeting window if you work primarily from Ho Chi Minh and need Hong Kong colleagues present.
