谈天谈地不谈恋爱谈钱谈心不谈感情
[tán tiān tán dì bù tán liàn ài tán qián tán xīn bù tán găn qíng]
'Talk about everything except love, discuss money but not emotions' suggests a humorous and cynical attitude towards avoiding discussions on serious romantic relationships, focusing instead on casual conversations or financial matters.
