Monk Li of Xichuan had a disciple whose back was so bent that they could not look upwards, and because the medicine market had closed, saw a Daoist, who said: “If the scholar has money, I beg two or three hundred cash for wine.” The scholar said: “I am poor and lack money, but there is some weak wine in my residence; will you have a drink with me?” The Daoist accepted happily and accompanied him. When the wine was half finished, the Daoist said: “Why is your back curved?” The scholar said: “Unfortunately I happened to suffer this illness; there is nothing to be done about it.” The Daoist therefore took out thirty grains of medicine, saying: “In the coming days, at the fifth watch (3-5am) face east, take these with freshly drawn water, and do not become alarmed if you feel a slight pain.” The scholar did as instructed and, having taken the medicine, felt an extreme and unbearable dryness, turning and thrashing on his bed and regretting it bitterly. Nevertheless, every time he stretched himself he felt slightly more comfortable, and by the next day his back was quite straight.
