The Mawangdui Silk Texts are texts of Chinese philosophical and medical works written on silk and found at Mawangdui in China in 1973. They include some of the earliest attested manuscripts of existing texts such as the I Ching, two copies of the Tao Te Ching, one similar copy of Zhan Guo Ce, and a similar school of works of Gan De and Shi Shen, as well as previously unknown medical texts like Wushi'er Bingfang ("Recipes for Fifty-Two Ailments"). Scholars arranged them into silk books of 28 kinds. Together they count to about 120,000 words covering military strategy, mathematics, cartography and the six classical arts of ritual, music, archery, horsemanship, writing and arithmetic.
