The Book of Changes was written at the end of Shang Dynasty in China, when Zhou Wenwang was only a courtier of Shang Dynasty. Later, Shang Zhouwang, afraid of rebellion, tricked him into Chao Ge and imprisoned him in the name of writing a book. Later, during his ten years in prison, Ji Chang wrote the Book of Changes. From then on, China culture began to have a new interpretation. Both Confucius' courtesy, righteousness, honesty and shame and Laozi's Taoism are inspired by the wisdom of the Book of Changes.
Many people think of fortune-telling and divination when they mention Zhouyi. The original function of the Book of Changes was indeed based on divination. The Book of Changes combines innate gossip with the acquired gossip, and uses Gankun to represent Yin and Yang. Laozi said, "Tao gives birth to one, life to two, life to three, and life to all things." Gan Kun was born in Yin and Yang in the Book of Changes, and the Eight Diagrams developed from this, resulting in sixty-four hexagrams, each of which combined the relationship between agriculture, weather and people and systematically expounded divination and geomantic omen. The Book of Changes has become the spiritual bond of ancient people in China, because as a divination book, it expounded people's spirit and will earlier than Confucius, and used natural laws to persuade people to do good.
The Book of Changes is the precious wealth of our Chinese nation, and the earliest China people with systematic moral norms. It became the foundation of later Confucian culture and China culture.
