Lu Han was a prolific philosopher and excelled in the field of Yi, with Yi Jing Zhong Shuo being his representative work. Lu interpreted Yili from the perspective of Lixue (Neo-Confucianism) and devised concise Tushi for 64 Gua (divinatory hexagrams) and Yi Zhuang. Following his predecessors Zheng Dongqing in the Southern Song and Liu Dingzhi in the Ming Dynasty, Lu specialized in 64 Gua, explaining Zhouyi with Yili thoughts, which made him prominent and distinct from other scholars of his time. Lu grasped the essence of the four virtues, Yuan, Heng, Li, Zhen, and explained their meanings through qian gua gua-ci (the description of qian hexagram). He further established his theory from the perspective of Tuanci Zhuan and Wenyan Zhuan. The present study aims to explore the important contents of Lu's views and the characteristics of Lu's thoughts in the following four aspects, corresponding to the four virtues: the relation to tian-dao (the Heavenly Way), tian-dao in relation to humanity, qian gua theory, and ren-dao (the Human Way), as well as the relation between Li and Taiji, hoping to give an objective indication of his role in Yi history and Tushuo Yixue.
