Sit still and always think about yourself. Don't talk about people's mistakes. Holding gold is precious. Know that happiness is worth 1000 yuan?

I think it is: always calm down and reflect on what you have done before (no matter right or wrong, try to correct mistakes). Don't talk about other people's shortcomings when chatting with them. Sorry, I didn't catch the third sentence. Happiness is more precious than a thousand dollars. I don't know what the third sentence means. Three sentences or four sentences together? That is,' gold is expensive, but if people are content, it is worth more than 1,200 pieces of gold' (if you translate poetry literally,' knowing happiness' may be the way to know happiness) Hehe, that's just my personal opinion.
