Classics survive throughout times and social changes. The popularization of classics signifies the respecting for the need of general public and naturally the expansion of readership. This process oftentimes follows the growing availability of education. While the monopoly of the "intellegentia" weakens, the vehicle of the classics also tends to transform into more popular and practical forms. The morality textbooks in Song and Ming Dynasties are good examples which manifest the liveliness and the passing-on of knowledge and thoughts. This paper examines the tendency of popularization in elementary textbooks after "Xinji Wenci Jiujing Chao" and "Taigong Jiajiao" in the Tang Dynasty. It focuses on materials of the same nature in Song and Ming, which are taken from "Mingxian Ji, Xiaoxue, Mingxin Baojian" and common encyclopedias such as "Shilin Guanji, Jujia Biyong Shilei Quanji" and "Wenlin Miaojin Wanbao Quanshu". It dwells on the issue of popularization of classics and discusses the cultural values and influences reflected through the process.
