How This Pair Actually Operates
Hanoi and Hong Kong still share most of the workday, so fast live alignment is practical without forcing one side into repeated after-hours calls.
Use a stable recurring slot and reserve async updates for prep and follow-up, not for the main decision itself.
This pair can usually decide live on the same day. Protect the strongest focus band instead of scattering short meetings across the calendar.
A fixed recurring slot is sustainable for this pair if it stays inside the shared focus block.
