Is Sanyang Kaitai from Zhouyi?

According to the Book of Changes, the connected hexagrams are Yang hexagrams, the broken hexagrams are Yin hexagrams, the first month is Tai hexagrams, and three Yang hexagrams were born the next month. When winter goes and spring comes, yin fades and yang grows, just like good luck. It is often used to celebrate the beginning of a year or to symbolize good luck. In the theory of Yin and Yang, October is Kun Gua. The image of pure yin. November is divination, and the sun is born in the next place. December is divination, and the second sun is born next. The first month is the Thai hexagram, and the next month is the birth of Sanyang.

When winter goes and spring comes, the yin disappears and the yang grows, which is like the prosperity of Ji Heng, so it is called Sanyang Kaitai.

In ancient China, Yang was homophonic with sheep, and sheep was Yang. Literally, "three suns" is interpreted as three suns, namely the early sun, the positive sun and the late sun. Chaoyang is bright, and its platform is bright; Zhengyang Zhongtian, whose platform is Xuan Lang; The setting sun is brilliant, and its platform shoots. They are all full of energy.

The origin of words

The original word of "Sanyang Kaitai" is "Sanyang Kaitai". It is not advisable to say that the word comes from the Book of Changes, but it can only be said that it uses the image of the Book of Changes. The original text of the Book of Changes (a part of the ancient Thai hexagrams) is as follows: On the ninth day of the ninth lunar month, plucking the hair, it is used for good luck. 92. Huang Bao and Feng He are not far away; If a friend dies, it will be better than the Bank of China. In 1993, there was nothing flat and vicious and there was no turning back; Don't regret it, there is food for the sky.

The image of the Book of Changes is more abundant and specific, "One Yang is born, the other Yang is long, and the third Yang is enlightened." It should be the language habit of later generations, and the image expressed is more inclined to the change of solar terms. Although there are expressions of yin and yang in the Book of Changes, it is not overemphasized that the cathode is full of yang and the anode is full of yin and yang, which is closer to Taoism and the theory of yin and yang.

Here, I would also like to talk about two parts of Zhouyi: the ancient classics and the Yi Zhuan. In the ancient classics, it is mainly gossip. Its basic composition is divided into yin and yang, plus three different orientations of "up, middle and down" (later called the three talents of heaven and earth). Gossip is a set of permutations and combinations, much like binary and ternary. It is not so much pure philosophy as mathematical knowledge.

As for the Yi Zhuan, there are many controversies in later generations. Some people think that it was written by Confucius, while others think that it was influenced by post-Taoism and Yin-Yang school, and it was labeled as Mencius and Xunzi. Therefore, it is difficult to determine the age of some words in Yi Zhuan.
