  We can get a broader notion of what these techniques were like if we turn to the list of titles from the “Recipes and Methods” section of the Han shu Bibliographic Treatise, mentioned above. One of the few extant texts it lists is the Huang Di neijing, along with the titles of lost medical works on nurturing life, health, and longevity. The “Classical Recipes” (jing fang) section includes titles such as “Recipes for Married Women and Infants” (Furen ying er fang 婦人嬰兒方) and “Food Prohibitions of Shen Nong and Huang Di” (Shen Nong Huang Di shi jin 神農黃帝食禁). The sexual arts section includes “Recipes of Huang Di and the Three Sage-Kings for Nurturing Yang” (Huang Di san wang yang yang fang 黃帝三王養陽方) and “Inner Chamber Recipes of the Three Schools for Having Children” (San jia nei ju you zi fang 三家內房有子方). Other sections describe physical exercises and therapeutic techniques, such as the “Stepping and Pulling Book of Huang Di and Other Masters” (Huang Di za zi bu yin 黃帝雜子步引 (Han shu 30, 1778–79).
