"Three stooges are better than Zhuge Liang" may be the myth of "three stooges are better than Zhuge Liang", that is, the homophonic words are misinformed into common sayings.
This proverb means that the wisdom of three ordinary people together should be able to top Zhuge Liang. In fact, the cobbler has nothing to do with Zhuge Liang. The cobbler is actually a homophonic myth of "a good general". In ancient times, "Bijiang" meant "Captain". The original meaning of this proverb is that the wisdom of three captains can top Zhuge Liang. Later, people actually called "Bijiang" "cobbler".
