There are many kinds of Tai Chi pictures, such as Zhou Dunyi's Tai Chi picture, congenital Tai Chi picture (formerly known as Nature's Picture of Heaven and Earth, commonly known as Fish's Picture of Yin and Yang), ancient Tai Chi gossip (with gossip symbols around the congenital Tai Chi picture), Lai Zhide's Tai Chi picture, Duanmu Guohu's Tai Chi picture in Qing Dynasty, etc. So far, people are only familiar with "Congenital Taiji Map" and "Ancient Taiji Bagua Map". Therefore, what modern people call "Tai Chi Map", that is, "Fish Map of Yin and Yang" or "Natural Map of Heaven and Earth", is said to have been passed down by Chen Tuan, a Taoist priest in the Song Dynasty. Chen Tuan, a Taoist from the Five Dynasties to the early Song Dynasty, had profound attainments in Inner alchemy and Yi Studies. According to historical records, Chen Tuan once distributed Taiji Map, Eight Diagrams Map, River Map and Luoshu to his students, and passed them to Mu Xiu and others respectively. Later, Mu Xiu passed the Tai Chi map to Zhou Dunyi the day after tomorrow. Zhou Dunyi explained it in Taiji Illustration. The Tai Chi map we are seeing now is the biography of Zhou Dunyi. On the one hand, Zhou Dunyi absorbed the Taiji schema theory of Chen Tuan School and made a new explanation. On the other hand, he inherited the tradition of Yi School since Han and Tang Dynasties ... and became a pioneer in the interpretation of Yi by Song and scholars.
