Which dynasty is Zhouyi from?

One of the Book of Changes and Three Changes (The Three Changes still existed when Liu Xiang collated the book in the early Han Dynasty, but its whereabouts were unknown after the Han Dynasty) is one of the traditional books, which is said to have been written by Zhou Wenwang Jichang, and its contents include The Book of Changes and Biography. Classics are mainly composed of 64 hexagrams and 384 hexagrams, each of which has its own interpretation (hexagrams) for divination. The Book of Changes did not put forward the concepts of Yin-Yang and Taiji, but was influenced by Taoism and Yin-Yang theory. There are seven kinds of words * * * 10 explaining hexagrams, which are collectively called the Ten Wings and are said to be written by Confucius.

During the Spring and Autumn Period, official schools began to evolve into private schools. There is a gradual development before and after the Yi-ology, and a hundred schools of thought contend, so it is easy to divide. Since Confucius praised the Book of Changes, the Book of Changes has always been regarded as a Confucian classic, the first of the six classics, but it is outside of Confucianism. "There are two schools of Yi-ology, which develop in parallel with Confucian Yi-ology: one is Yi-ology, which still exists in the old forces; The other is Laozi's Taoist Yi. Therefore, since Confucius praised Yi, China Yi-ology began to be divided into three branches.
