Look at the "Overseas Southern Classic" in the "Classic of Mountains and Seas", there is a paragraph about the head of the country. The country of Zhentou is also called the country of Danzhu. Danzhu was the eldest son of Yao, the leader of the ancient Chinese tribal alliance. According to legend, because Dan Zhu was not good, Yao gave up the position of the leader of the tribal alliance to Shun. Sima Qian's "Records of the Five Emperors" said: "Yao Pi's reign collapsed in the twenty-eighth year. The people mourned like the loss of their father and mother. For three years, the Quartet is not happy, and it is Siyao. Yao Zhizi Danzhu is not good, not enough to give the world, so he is the right to give Shun. If Shun is awarded, the world will benefit from Danzhu disease; If Danzhu is awarded, the world will be sick and Danzhu will benefit. Yao said: 'In the end, no one will benefit from the disease of the world. And he gave Shun the world. ”
After the death of Emperor Yao, Shun gave up the throne to Danzhu and kept filial piety for Yao for three years. Three years later, Danzhu was not good at politics and was still located in Shun.
In addition, Danzhu is also the earliest "chess saint" in the Chinese Go world, and is the ancient second ancestor of the Qi family and the Liu family.
My grandson likes Go, and his chess skills are pretty good, but I can't beat him anyway. I wanted to test him today and asked him if he knew who the earliest chess master in the Chinese Go class was, and he actually knew.
It seems that people have to keep learning, otherwise they are not as good as a third-grade child.
