Yuanshengjiating means 'family of origin'. It is a psychology-flavoured term for the household you grew up in, used in Chinese public talk for the idea that it shapes your adult choices and wounds. The word spread through online discussion and dramas, often in stories about parents who demand things from a grown child. Ode to Joy fed that conversation with the storyline of Fan Shengmei's family.
