From Wang Yangming’s “Contemplation of Yijing” to Sun Ying’ao’s “Expression of Yijing”

From Wang Yangming’s “Contemplation of Yijing” to Sun Ying’ao’s “Expression of Yijing”, there exists common point in main threads of thinking and criterion. General speaking, they fellow the pattern of taking “Lu and Wang School” (a school led by Lu Jiuyan and Wang Yangming who believed that the heart is the source of universe) to explain “Yijing”, and “Yijing” to prove the school’s research of Yijing. Specifically speaking, they are similar in many ways, such as outlook of substance function, methodology, and understanding the aim of “Yijing”. These show that Sun Ying’ao’s “Expression of Yijing” inherits and develops Wang Yangming’s “Contemplation of Yijing”.
