真香警告

Meaning

"Zhenxiang Warning" originates from Hunan TV's "X-Change" where city protagonist Wang Jingze made bold declarations when first arriving at a rural home, only to completely contradict himself later in a comedic turn. Refers to someone firmly deciding not to do something, then ending up doing it anyway. Now mainly used to describe "face-slapping" situations where behavior or attitude completely reverses.
