Creating a floor plan for Zhao Yunlan's apartment (with a detour through Shen Wei's)

Today, by which I mean "yesterday" because typing this took forever, I decided to spend my day doing something I'd been putting off for months–figuring out what the hell is going on with Zhao Yunlan's apartment (and also Shen Wei's, because their layout is actually the same).

So this is what I came up with:

(We kinda were, but not exactly.)

Spoilers: Fun fact: I've officially come to the conclusion that Shen Wei's apartment doesn't have a kitchen.
