[Siheyuan courtyard + emotional-breakdown System + entrepreneurship + transmigration + a head start on everyday life] The post-2000s generation really can't keep up with the rat race anymore.

Just watch how I mess with you.” “Yan Bugui, you old geezer, you love putting on airs, don't you? I'll give you all the airs you can handle.” “Yi Zhonghai, step down! I'm going to be the head of the courtyard.” “Teacher Ran, just try not marrying me. See if you regret it.”
