自己浪荡就别说社会肮脏
[zì jĭ làng dàng jiù bié shuō shè huì āng zàng]
A rather blunt statement meaning 'Don't complain about societal filth if you yourself lead an indulgent lifestyle.' It reflects a self-awareness or criticism about personal behavior relative to society's standards, often used to express disappointment in oneself or others.
