Zhou Bixian was supervisor of the Panfeng wine store in Wuxi County, Changzhou. He used fragrant medicinal material to produce his yeast, bringing forth a dense fragrant cloud. The flavour of his wine was pure and clear, and it was produced in top, middle and lower qualities. When distilling the wine, he made offerings to deities, slaughtering a sheep and a pig, carrying out the rite of the three offerings in his official robes, and when this was complete sending the wine out to all levels of officials at the court. One day, at the autumn offering, the storehouse clerk came reporting that there were holes in the clay of the highest grade wine flasks. When he was taken to see, several hundred flasks were indeed quite empty. The clerks thought it strange that those chosen and cleaned as offerings to the spirits had not been affected, and nobody knew the cause of it all. A month later, laughing voices were suddenly heard in the wine store, and when they peeped in they saw a crowd of children sucking from the mouths of the wine jars; when the doors were opened they all vanished into the earth. He hastily ordered that the floor be excavated, and at a depth of three chi (about 1m), they found a huge serpent lying drunk, with several dozen smaller snakes wound around beside it, and they realized that those spoiling the wine were snakes. His heart weighed down with doubt and bewilderment, gloomy and without joy, [lacuna] within two months he had resigned and returned to his home region.
Anon., Huhai xinwen yijian xuzhi, 後2.258 (Tale 469):
周必先監無常州錫縣潘封酒庫，用香藥料造麯，香氣氤氳，酒味清洌，有上中下三等。酒熟祭神，刺羊刺豕，庫官展裹行三獻之禮，事畢分送朝官監司太守以下。一日秋祭，庫吏走報，謂上等酒瓶泥皆有孔，取而視之，則數百瓶皆空空如也。官吏以為怪，擇其潔者供祀神，不之顧，亦莫知所自也。越一月，忽聞酒庫有笑語聲，潛視之，則有羣小兒口吸瓶上，開門則失入地矣。急命掘地，深三尺，有巨蛇醉卧，數十小蛇旋繞其旁，始知壞酒者此蛇也。其心疑怪，鬱鬱不樂， [ ] 踰兩月以事罷歸。
