The earliest descriptions of Lan Caihe come from Song anecdote collections and are unusually specific. The figure wears a torn blue gown and a black wooden waistband three feet long, has one foot bare and one shod, wears a padded jacket in the height of summer, and lies in the snow in winter with steam rising off the body. The setting is always a market or a street, never a temple.
The performance is the point. Lan Caihe carries a pair of large castanets, sings improvised verses to crowds, and is usually drunk. The songs are about the shortness of life: the accounts preserve lines about a peach tree in blossom seen how many times, about riding a stag or a crane and travelling faster than one wants to, about people who go and do not come back. Coins thrown by listeners are strung on a long cord and then dragged along the ground behind, so that they are lost as fast as they are earned, or given to the poor, or spent on wine.
The departure is as public as the rest of it. At an inn at Haoliang, in the middle of drinking, Lan Caihe hears music in the air, rises on a crane or a cloud, and goes, dropping the gown, the belt, the castanets and the one boot, which fall to the ground and are picked up by the crowd and then vanish in turn.
