Xueji is an ancient educational paper in China, one of the monographs of ancient laws and regulations in China, and the earliest educational and teaching monograph in China and even in the world.

Tian Huisheng, Dean of China Academy of Educational Sciences, and Li, Professor of Nanjing Normal University, talk about teaching: Xue Ji is the first monograph in China that systematically discusses teaching ideas. It is not only a summary of China's ancient Confucian teaching thought, but also the earliest monograph on teaching problems in the world.

It is generally believed that this is the work of Meng Si School at the end of the Warring States Period. According to Guo Moruo's textual research, the author is Ke. Gu Shusen supported Guo Moruo's view that Xue Ji was written by Le Zhengzi, a Confucian scholar, at the end of the Warring States Period, and borrowed ideas from the school, probably by Ke, a disciple of Mencius.
