Hanoi×Nukuʻalofa
Three numbers. The ones that decide the meeting.
When the world meets at work.
Read the day in both zones.
Crossing the border. Money, language, plugs.
Money changes hands at the border: Hanoi uses the VND (₫) and Nukuʻalofa uses the TOP (T$). Language shifts too — Vietnamese in Hanoi, English in Nukuʻalofa. Be careful behind the wheel: Hanoi drives on the right, Nukuʻalofa on the left.
