Who invented Go? Is there a chess player?

There has always been a saying that "Yao made Go and taught his son Dan Zhu", that is, Emperor Yao invented Go to educate his son Dan Zhu. But this, like Cangjie's word-making, is a common legend in China that pretends to be a saint. It is said that Weiqi originated from a divination method.

I wonder what the question "Chess Saint" refers to? If there are many people with this title, the most famous one is Huang Longshi, the chess saint who is also called "Fourteen Saints" with thinkers Huang Zongxi and Gu. There is also the "Showa Chess Saint" Wu Qingyuan who travels to Japan; Japan's Efang Hideyoshi should also count. Now "Chess Saint" has become the title of Go. As the title awarded to the champion of this competition, more "chess saints" will be awarded.
