In early China, all the learned and knowledgeable people gathered together in the official system. It says in Quli, Part I, The Book of Rites (《礼记·曲礼上》): “teaching was carried on only by official scholars in their governmental capacity,” which reveals that the origin and master-apprentice relationship of different trades all came from the early government system. At the beginning of the civilization, the Shang (c. 1600 BC-1046 BC) and Zhou (1046 BC-256 BC) governments worked as the public management institution of social undertakings, and fostered the “forefathers” of all walks of life. The Chinese character 学 (“learning”) itself originated from the royal court and aristocratic life. Learning (学) evolved into a mature knowledge system after the Western Zhou Dynasty (1046 BC-771 BC). By the Warring States Period (475 BC-221 BC), the intellectual class began to be independent rather than relying on officialdom. Summary of Philosophical Masters (《诸子略》) by Liu Xin (刘歆) directly connected learning with official posts, and expounded and analyzed the origin of official posts of various schools one by one. The control of the king of the Zhou was weakened when the Zhou declined, the free political atmosphere directly led to the unprecedented prosperity of studies of the scholars. Although there are differences among the various schools of thought, they are “different paths” and “hundred concerns,” but they all originated from the “Six Classics” and are all tributaries or variants of the learning of officials of the imperial court. Therefore, the “Six Classics” are their “same origin” and “uniformity.”
