In the Xianchun era, on the sixth day of the fourth month in the yichou year (23 April, 1265), the clerk Xia Yingchen of the Tanzhou government office made a report in an imperial bulletin, and one section within it read:
In Shenwenjiang County, Chengdu Prefecture, there was a mottled yellow snake, more than a hundred zhang (a zhang is about 3.3m) in length, a spirit radiance extending more than three hundred paces around, its mouth spitting out a fragrance of pepper and plum flowers, its vapour scorching more than twenty li; those people and animals killed by it are innumerable. On the third day of the seventh month last year (27 July, 1264), this prefecture gathered more than two thousand five hundred soldiers to apprehend it, but the serpent used its tail to turn and sweep the troops away. More than five hundred were drowned, and the rest all fled in terror. The emperor decreed that the Daoist Masters of Shu use their powers to deal with the matter; they have just slain it, and its bones are like mountains.

成都長蛇
咸淳乙丑四月六日,潭州書局夏應辰錄邸報從遞來,內一項云:「成都府申溫江縣有黃花斑蛇一條,長百餘丈,神光照三百餘步,口吐椒梅花香,薰灼二十餘里,殺人畜無數。去年七月三日,本府差甲士二千五百餘人收捕,蛇用尾掉卷軍士,溺死者五百餘人,餘皆驚遁。上旨命天師蜀中有法之士治之,方戮死,骨如山。」
