Abstract: This paper re interprets and interprets“sanjue sanqi” (三絕三棄) through two versions of Laozi: the Ancient Chu Literatures Carved on Bamboo Slips Excavated at Guodian and the Silk Manuscript, and holds that the content of chapter‘sanjue sanqi”is directly related to chapter‘Baoxun” (《保訓》) in Tsinghua Bamboo Slips of the Watring States Petiod and “Wenzhuan” (《文傳》)，“Wenxun” (《文儆》) in Yizhoushu (《逸周書》) . In this chapter, Lao Zi quotes King Wen's instructions to King Wu, taking the self-restraint of the monarch as an example to explain how to cultivate the mind. Through the comparison of words and meanings, this paper studies the relationship between the chapters of Laozi in the versions of Ancient Chu Literatures Carved on Bamboo Slips Excavated at Guodian, Silk Manuscript, the Han Dynasty Bamboo Slips of Peking University and Wang Bi (王弼) , and holds that the Ancient Chu Literatures Carved on Bamboo Slips Excavated at Guodian is the manuscript of Silk Manuscript Laozi, which is the origin of all later versions. The study of the Silk Manuscript Laozi should focus on the factors such as reason, historical facts, exegesis and grammar, especially make full use of newly unearthed documents, so as to gain a new understanding of Daoist thought, concept and knowledge system.
