There are several versions of the Book of Changes.

Legend has it that there are three versions of the Book of Changes, that is, the Book of Changes has three systems since ancient times: Lianshan Yi, Guizang Yi and Zhouyi. "Lianshan Yi" begins with a hexagram, which stands for mountains and mountains, meaning "beyond the clouds, the mountains are endless"; The book "Returning to Tibet" begins with Kun Gua, which represents the land and symbolizes that everything was born in the land and eventually returned to Tibet. The Book of Changes is said to have been created by Zhou Wenwang of the Zhou Dynasty, hence its name.

There are also different opinions about the formation time of the three versions: First, Lianshan Yi was formed in Xia Dynasty, Guizang Yi in Shang Dynasty and Zhouyi in Zhou Dynasty; First, Lianshan Yi was formed in Fuxi era, Guizang Yi was formed in Huangdi era and Zhouyi was formed in Zhou Dynasty.

Philosophical thought:

The philosophical thinking of ancient scholars in China was inspired by the study of the Book of Changes, and their philosophical thinking ability was mostly trained and improved through the analysis and interpretation of the Book of Changes and the contention of different viewpoints. Laozi integrated the ideological essence of Yijing into Tao Te Ching and founded a philosophical system with dialectical thinking as the core.

On the basis of the combination of yin and yang to form hexagrams, he constructed a schema of the origin of all things, revealing the unity of opposites of various forces contained in things. "Everything is negative and holds Yang, while rushing to think that it is harmonious".

The idea of embracing Yin and Yang is still a clear symbol in the Book of Changes, but in Laozi, I have an analysis of various concrete things. In the meantime, the proposition that has the greatest influence on China's philosophy in later generations is "misfortune is the basis of happiness;" Happiness lies in misfortune. " Of the two sides of the contradiction, one is the main one and the other is the secondary one. The extremes of things are opposite, and the idea of mutual transformation of opposites is reflected in the Book of Changes by using good and bad endings in different positions of hexagrams.

Taking Laozi as an example, it has reached all aspects of society, politics and ethics. Flexion is complete, waste is straight, depression is surplus, cover is new, less is gained, and more is confused. I think compromise always comes from preservation. The way of thinking of weaving evidence is the way I observe the world.

The sage holds that "one is the wind of the world", and he uses this truth to dialectically sum up all things in the world, that is, a strong army is destroyed, a strong wood is broken, and a strong one is weak. He also used this law to put forward a series of specific methods to deal with problems. Laozi's dialectical thought inspired by the Book of Changes has written a bright chapter in the history of China's philosophy.
