The four books, Daxue, The Doctrine of the Mean, The Analects of Confucius, Mencius, The Book of Songs, Shangshu, Zhouyi, Li and Chunqiu, have become the official textbooks of people's thoughts and behaviors for more than a thousand years. The Great Learning and The Doctrine of the Mean were originally two of the forty-nine books in the Book of Rites handed down by Dai Sheng in the Han Dynasty. The Book of Rites has been listed as a scholar (doctor of the Five Classics) since Xuan Di, the Emperor of the Han Dynasty. The Analects of Confucius became a specialized subject in the Han Dynasty and was taught by a special person. He was listed as a scholar in Wei State. Later, when Confucianism respected Mencius in the Song Dynasty, it was gradually juxtaposed with the Classic of Filial Piety, The Analects of Confucius and Erya, which was used to test scholars and became an official school. The imperial examination was resumed, and the classics were tested (the classics were the four books and five classics, and the techniques were the techniques of Zhouyi and Eight Diagrams) until Yuan Renzong Yanyou (13 14- 1320). And Zhu's "Zhu Ji Zhu" selects scholars through stereotyped writing in Ming and Qing Dynasties, which is also following suit.
Second, the cultural background of military books:
When it comes to books by military strategists, Sun Tzu's Art of War, Thirty-six Plans and so on immediately come to mind.
Third, the geomantic culture of Zhouyi:
Speaking of the geomantic culture of Zhouyi, it is the most noteworthy and controversial cultural heritage today, which is also the most critical content of this paper. The culture of the Four Books and Five Classics I mentioned earlier can be summarized in a very simple way. The following is the central argument of this paper-the geomantic culture of Zhouyi: Zhouyi, also known as the Book of Changes, is often referred to as the Book of Changes in the ancient notes on the Four Books and Five Classics. According to the data, it has always been regarded as an encyclopedia of China's culture and technology, covering astronomy, meteorology, physics, mathematics, military science, medicine, qigong, sports, martial arts and even prophecy.
