On the basis of Chen Tuan's Wuji Map, Zhou Dunyi created Taiji Map. Mao Shu of Zhou Dunyi, whose real name is Lianxi, "Learn from the times, write Tai Chi pictures, the root of understanding, and the end of all things." (Zhou Dunyi's Biography of the Song Dynasty) Zhou Dunyi's Taiji Tu and Taiji Tu Shuo were transformed from Chen Tuan's Wuji Tu by absorbing Taoist theory. Huang Zongyan's "Graphic Puzzlement" said: "This picture was originally called" Infinite Map ",which was the skill of the alchemist ... Zhou Zi got this picture, but it was easier to change its name by reversing its order, and it was attached as a secret biography of Confucianism." In Illustration, the concept of "infinity" and the proposition of "quietness without desire" in Taoism and Taoist thought were adopted, which revised and enriched the cosmology and ethics in the original ideological system.
There are more than 200 words in illustrations, among which "Wuji" is mentioned three times: one is "Wuji and Taiji"; First, "Tai Chi is infinite"; One is the infinite truth, which holds that Taiji originates from infinity, infinity belongs to existence, infinity is nothing, and it is the origin of the universe. In this way, on the basis of absorbing the Taoist concept of infinity, Zhou Dunyi established a new category of the theory of the origin of the universe, which became the Taoist theory of the generation of the universe.
