I have in-laws living in China, and honestly - it’s a lot easier to navigate those sorts of high rises than you might think.
Most residential buildings I’ve visited have lots of dedicated lifts, so only 2 apartments per floor share one lift. So you would only need to provide something like: Tower 37, Floor 19, Apartment 2.
The Chinese love their delivery apps, too - their drivers (technically scooter riders) are very used to this.
Now the city of Chongqing is a whole seperate matter, that place is an M. C. Escher drawing in real life!
The American brain should be perfectly adapted to this sort of scenario! Just think it like one of those suburban cookie-cutter HOA developments, but vertical!
As for counting with multiple numbers, y’all love to do that already! feet & inches, pounds & ounces etc.
