In English we use “please” a lot. Use it and you’re polite. Don’t and you’re rude. So an English speaker learns the word 请 [qǐng], often translated “please”, and starts throwing it around in Chinese. Problem is, that’s not how Chinese use 请.

Many of the simple words one relies upon in one’s native language don’t exist in other languages – not in the form one is accustomed to. For example, in China it’s uncommon to say 谢谢 when the person is doing something they are paid for.
