Are there any interesting words to describe a picky person in your language? In Mandarin, we call the picky person as 挑剔的人. Meanwhile, there are lots of words to express the meaning of criticizing others, for example, 评头品足， 吹毛求疵，鸡蛋里挑骨头 and the like. You can understand 鸡蛋里挑骨头 directly, which means a person pick a bone in an egg. Then, you know how fussy the person is. In Cantonese, I remembered that some actors or actresses will say 百彈齋主 to describe somebody is very picky or fussy. The 彈 in here means criticize. There are also some same usage of sentences about 彈 in Cantonese. “有人讚，有人彈” means some people agree/praise, others criticize. ''識彈唔識唱” is used to describe somebody can only complain but can not suggest.
