矮子里面选将军

矮子里面选将军

Literally means:

choose a general from among the dwarfs

Actually means:

pick the best out of a mediocre bunch

矮子 means a short person. Ancient people believed that short men were not qualified to be a general, and that only tall men could be the good choice.

This phrase figuratively means choosing better men among a group of mediocre people.

It implies that there is no better choice.

矮子，个子矮的人。古人认为个子矮的人不合适当将军，只有身材高大的人才有机会入选。

比喻从差的里面挑选比较优秀的。含有没有更好的选择，只能凑合、将就的意味。
