you really low class angmoh ticket.
Many words (in all languages the same) used name of physical things similar in sound, or tone, for words of non-physical things, borrow the sound lah!
For example, 我们 and these 2 words add together (2 sounds) in Chinese is 'we'. So closest and common word door '门‘ is used to express the sound 们 but add 人子边 to be 们 when writing.
So for you it will be Chinese like to bang door here and there when you hear 你们, 我们 , 他们?
You makan too many angmoh potatoes?
You stupiak Mat or Indian? Kachao Cina is it?
As I have said, MOE under KFC Tan are bad PAP lapdog, sleep at work and not teach Chinese well in PAP school system. Instead want to destroy Chinese and succeeded in making people like you?
Still don't get it?
