十个手指有长短

十个手指有长短

Literally means:

10 fingers are different in length

Actually means:

Fingers are different in length. This phrase metaphorically means that people or things are different. It is often used to indicate that people or things should not be treated or judged by a unified standard and that we can't expect everybody or everything to be all the same.

一个人的十个手指的长短都不一样。比喻人或事物总是有差别的，不可能完全一样。多用来指不要用一个统一的尺度来衡量或看待有差别的人或事，更不可以强求一致。
