What concept did Yi Zhuan use to establish the basic framework of Confucian organic cosmology?

Yi Zhuan made a comprehensive study of heaven, Taoism and humanity, trying to establish an all-encompassing and well-prepared philosophical system. The Book of Changes holds that the Book of Changes contains the principle of change and is the supreme law of all things in the universe. "It is easy to fit in with heaven and earth, so it can help us understand the way of heaven and earth." Heaven, Tao and man are all one Tao, and they are the embodiment of justice in all aspects of nature and society. Therefore, it is said that "easy to be a book, come prepared, and one day, someone has a way and a tunnel." What is Yi Li? The interpretation of Yi Zhuan is: "Fate is called Yi". "The size of heaven and earth is innate." Yi Zhuan established the basic framework of Confucian organic cosmology with a dynamic concept.
