I can't believe I haven't seen any fic that incorporates that pole or the swing in Zhao Yunlan's apartment. COME ON PEOPLE.
I think it's because the swing is clearly a kiddie swing and also very much hidden by all the other crap, instead of a sex swing he can use for sexy purposes. (But mostly just that no-one noticed it.)

You can be the Woman Laughing Alone With Salad of many an advertisement! :D
