Huangdi Sijing
The Huangdi Sijing (simplified Chinese: 黄帝四经; traditional Chinese: 黃帝四經; pinyin: Huángdì sìjīng; lit. "Yellow Emperor's Four Classics") are ancient Chinese texts thought to be long-lost, manuscripts of which however are generally thought to have been discovered among the Mawangdui Silk Texts in 1973. Also known as the Huang-Lao boshu (simplified Chinese: 黄老帛书; traditional Chinese: 黃老帛書; pinyin: Huáng-Lǎo bóshū; lit. 'Huang-Lao Silk Texts'), or Huangdi shu 黄帝書 (Yellow Thearch Manuscripts), they are thought by modern scholars to reflect a lost branch of early syncretist Daoism, referred to as the "Huang–Lao school of thought" named after the legendary Huangdi (黃帝; "Yellow Emperor") and Laozi (老子; "Master Lao"). One finds in it "technical jargon" derived of Taoism, Legalism, Confucianism and Mohism.
