  Another medical text from Mawangdui is a recipe (fang 方) manual titled Recipes for Fifty-Two Ailments (Wushier bing fang 五十二病方, translated and discussed in Harper 1998). Recipe texts also have been excavated from Zhangjiashan (Li Ling 1993 and 2000). In addition, the Mawangdui tombs also contained hexagram divination texts and charts and diagrams on cloud divination and physiognomy, including the oldest known representation of a comet (Li Ling 1993).
