Abstract: The system of Confusianism literature preliminarily took shape in Western Han Dynasty with two reasons. First, emperors advocated compiling, collection, printing and circulation of books among citizens, for instance, Hui Di empowered people to collect, print, buy and sell books freely, Wu Di appointed officials to write books, and Cheng Di collected old books around the country. Then abundant traditional classics reemerged, which not only laid foundation for the composition of Seven Classics, Nine Classics and Thirteen Classics, but also paved the way for the 'banning all the other schools of thought, while honoring the Six Calssics of Confucianism' in Han Dynasty. Secondly, the great respect for Confusianism, the establishment of five-classics doctor, and the regular teaching of Confusianism literature brought about the appearance of abandant annotation for classics, such as Biography in Qin Dynasy, Jia Fa, Zhang Ju, even Chen Wei in Western Han Daynasy. Zhang Ju and Chen Wei prevailed once in Western Han Dynasty, but disappared from history for its undisguised flattery to the society and worthless in academe.
