Ask no questions and hear no lies.
Don’t ask questions which people can’t or don’t want to answer. If you ask such questions, you’ll hear only lies.
Example: When I asked my neighbour why he comes early from office on some days, he, in a wishy-washy tone, said that on such occasions he finishes his work early. Before asking this question, I should have remembered: Ask no questions and hear no lies.
The silly questions like
I often heard from dining tables: 好吃嗎?
Or a woman directly ask you: Am i pretty?
Who the hell would say no? unless you want to get yourself into trouble.
I would never ask anything like that.
I observe instead; actions speak louder than words.
