what do you means?什么意思？mean需要加s吗 和 which means?什么意思？ 的差別在哪裡？如果不好說明，請提供一些例句。

@jingqi Are you asking: what is the difference between "what do you mean?" and "which means?" in English? Your question is slightly unclear 😅

"Which means?" is not a complete question. "Which" refers to something that was said previously. For example: "Do you want to go out with me tonight?" "I can't, I have a ... a thing I have to do." "...Which means?" "I have a date." It's quite direct and blunt, so it's probably used between friends, or from a teacher to a student. Not from a student to a teacher. "What do you mean?" is a more common question, and you can ask this in almost all situations. For example: "你干嘛呢？" "What do you mean?" "I mean, what are you doing now?"
