Why is White Tiger Yi Tong a Confucian code?

Confucian classics are taught in strict accordance with the teachings of teachers and legalists, and it is inevitable that various opinions will be formed. In order to eliminate the contradiction between Confucian classics and kingship and the internal differences in Confucian classics, feudal emperors often personally intervened in academic discussions. In the third year of Ganlu (the first 5 1), Xuan Di, the Emperor Gaozu, "called Confucianism to discuss the similarities and differences of the Five Classics" and held a command academic conference, which was called "Shiqu Tingyi" in history. Twenty-two people, including Dr. Shi Kan, Yi Xue, attended the meeting. The meeting decided to add The Book of Changes by Doctor, The Book of History by Xia Houdun and The Spring and Autumn Annals. Shiqu Pavilion is an important meeting in the history of Confucian Classics in Han Dynasty, paving the way for the establishment of a unified Confucian Classics. But it didn't completely solve the problem. In the fourth year of the Eastern Han Dynasty (79), Emperor Zhang came forward again. "General, doctor, doctor, lang guan, students, Confucianism will discuss the similarities and differences of the Five Classics. ..... The emperor called it a temporary decision, such as Xiao Xuan's story of Mannan Stone Canal, which was written as "White Tiger Discussion". " Bai Zou has been lost. After the meeting, there was a book "White Tiger" edited by Ban Gu. This is a collection of Confucian classics since Dong Zhongshu, and it is also an imperial Confucian code. White Tiger Yi Tong is more prominent than Dong Zhongshu's Spring and Autumn Stories, which emphasizes that "monarch, father, mother and son" have supreme power, and subjects must absolutely obey the will of the emperor. In this way, Confucianism has completely become a vassal of kingship.
