沉默是金哑巴就是土豪
[chén mò shì jīn yā bā jiù shì tŭ háo]
Translates to 'Silence is golden, and a mute is a tycoon'. It implies that silence is valuable like gold and further exaggerates with saying a mute person (who cannot speak at all) is extremely rich. It’s often used humorously, hinting that sometimes not speaking up pays off.
