沉默是金那哑巴就是土豪
[chén mò shì jīn nèi yā bā jiù shì tŭ háo]
There's a proverb in China saying 'silence is golden', so people who remain silent all their lives would have lots of gold, thus implying they're 'big spenders'. It's used humorously, reflecting on situations where silence seems advantageous or valued.
