I’ve been playing with Red Note and stumbled upon a map of Shenzhen that provides price per square meter by subway station. I’ve realized that (1) I live in the cheapest part of Futian and (2) it really is cheaper to live in parts of the city that have metro connections but no real social infrastructure.

In turn, the uneven distribution of social infrastructure returns (also on Red) results in classification of beasts of burden (牛马) based on where one lives. (I’ve annotated where useful.)
