Pinyin:
jīdàn lǐ tiāo gǔtou
Meaning:
比喻故意挑毛病，没有毛病也要找出毛病。
to look for a flaw where there is none; nitpick
Character breakdown and explanation:
鸡蛋：egg
里：inside
挑：nitpick; find fault
骨头：bone
This expression literally means “to look for a bone in an egg.” Since there are no bones in an egg, this expression is therefore used to describe looking for a flaw where there is none.
Example sentences:
你男朋友各方面都不错啊，你就别鸡蛋里挑骨头了。
