三脚猫 (sānjiǎomāo) Jack of all trades and master of none

Usage:

“三脚猫”是指什么都懂一点儿，什么都不精通的人。“三脚猫”最早指的是只有三只腿却被人当成飞熊的猫。后来指捕鼠技能很不错，却“走不成步”的猫。久而久之，“三脚猫”一词成了做事技艺不精的意思了。
The meaning of “三脚猫(sānjiǎomāo)” is equivalent to “jack of all trades and master of none” in English. At first, the word referred to a three-leg cat which was mistaken by people for a flying bear. Later, the word indicated the cats which were skillful in hunting but had difficulty in walking. Gradually, the word is changed to mean being unprofessional in doing things.
