There was once somebody called Ba, from Qiong, his surname has not been recorded. He had a tangerine tree, and after the frost came all of the tangerines had been gathered, save for two big ones, each as large as a wide-bellied pot. Ba then ordered that they twist off the tangerines and weigh them, just like the usual ones. When cut open, each contained two elderly men, beard and eyebrows hoary white, flesh and bodies bright red, and both sets were playing chess, their bodies a little over a chi (33cm) in height, talking and laughing as if nothing had happened. When their games were finished, one old man said: “The gentleman has beaten me.” Another old man said: “The gentleman has beaten me; it will come back to me later, at the thatched hall at Qingcheng.” (This is a celebrated Daoist mountain site in Sichuan) Yet another old man spoke up: “Master Wang is always like this; waiting and getting nothing. Playing in the tangerine is no worse than on Shangshan, but you can’t have more than one stem for each tangerine.” One of the old men said: “Your servant is hungry and empty; he needs a dragon root fruit to eat.” Then from his sleeve he removed a grass root, about an inch across, its shape curving sinuously like a dragon, and, millimetre by millimetre and with great care, pared it away fully. When he had finished eating, he spat it out in a gush of water, and it transformed into a dragon. The four old men mounted it together, and wings flapping beneath their feet ascended into the clouds. Briefly and suddenly came wind, rain, darkness and light, and none knew where they had gone.
