Zhou Dunyi drew the Taiji Diagram through his interpretation of the concept of Taiji in Xici, but his Taiji Diagram and Zhu Xi's Taiji Diagram Explanation explained Taiji with Wuji and used Taiji-Two Instruments-Five Elements replaced the Taiji-Two Instruments-Four Images-Eight Trigrams cosmic creation system in The Copula. Mao Qiling, a scholar at the beginning of the Qing dynasty, strongly criticized this. Although these critiques have been overturned from justification, it is a fact that the thread of the Taiji Diagram theory is contrary to the line of thought. On the basis of Huang Zongxi, Huang Zongyan and Mao Qiling, Hu Wei achieved a complete dichotomy of the relationship between the Taiji Diagram and the Zhouyi studies by removing the Taiji Diagram from Zhouyi.
