From Pop Lyrics to Digital WisdomThe phrase originated in 2010 from Yoga Lin's song Lie, where the line 『Life is already so hard, some things shouldn't be exposed』 struck a chord.

Semantic Expansion (2017-present): Spawned variants like 『rén jiān kě chāi』(intentionally creating awkwardness) and 『rén jiān qiáng chāi』(malicious exposure)
