Liu Shu's "Capital Tongzhi Outside the Prison" said: "Prosperity in prison is easy." Su Zhe's "Ancient History" said: "The reason why Wen Wangfang was imprisoned was because the ancient gossip was sixty-four, so it was called Zhouyi."
It is said that the Taiji diagram of Taoism was created by Chen Tuan in the Song Dynasty. Originally called "infinite graph". According to historical records, Chen Tuan once passed the Tai Chi Map to his students for planting, and passed it to Mu Xiu and others respectively. Later, Mu Xiu passed the Tai Chi Map to Zhou Dunyi. Zhou Dunyi wrote Taiji Illustration to explain it. The Tai Chi map we are seeing now is the biography of Zhou Dunyi.
