Because Confucianism achieved a monopoly on ideology in the Han dynasty, the “jingxue”, or the “Study of Confucian Classics”, also achieved the central role in the academic realm ever since. The “xunguxue”, or Chinese hermeneutics, is the unique Chinese discipline that emerged when Han scholars interpreted Confucian Classics. On the one hand, the Confucian scholars of the Han Dynasty developed many principles and measures of interpreting Classics, which further developed into different schools of “shifa” (or master’s doctrines) or “jiafa” (or specialist’s doctrines). A good example is Zheng Xuan, who made notes to most of the Confucian Classics, and his annotations showed his methods and principles of “xungu”. On the other hand, they also wrote many dictionaries and linguistic works, such as Yang Xiong’sYang Xiong(扬雄, 53BC-18AD), with the adult name Ziyun(字子云) Fangyan (or the Vernaculars), Liu Xi’s Shi Ming (or Explanation of the Terms), and Xu Shen’sXu Shen(许慎) Shuowen Jiezi (or Interpreting the Characters).
