Huangdi Sijing

The Huangdi Sijing (simplified Chinese: 黄帝四经; traditional Chinese: 黃帝四經; pinyin: Huángdì sìjīng; lit. "The Yellow Emperor's Four Classics") are long-lost Chinese manuscripts that were discovered among the Mawangdui Silk Texts. They are 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"), in association with the "Huang–Lao" philosophy named after the legendary Huangdi (黃帝 the "Yellow Emperor") and Laozi (老子 "Master Lao"). They are thought by modern scholars to reflect a lost branch of Daoism, referred to as the "Huang–Lao school of thought".

One finds in it "technical jargon" derived of Taoism, Legalism, Confucianism and Mohism.

Mawangdui is an archeological site, comprising three Han-era tombs, found near Changsha in modern Hunan Province (ancient state of Chu). In December 1973, archeologists excavating "Tomb Number 3" (dated at 168 BCE) discovered an edifying trove of silk paintings and silk scrolls with manuscripts, charts, and maps. These polymathic texts discussed philosophy, politics, medicine, Daoist yoga, Yin and Yang, and astronomy. Most were unknown in the received literature, ranging from a formulary that modern editors entitled Recipes for Fifty-Two Illnesses and two texts on cauterization – the Zubi Shiyi Mai Jiujing and Yin Yang Shiyi Mai Jiujing, both precursors of the Huangdi Neijing – to the unknown Book of Silk, which lists three centuries of comet sightings.
