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!
