《太平广记·卷四百五十七·蛇二》
有一天晚上，有大风雷震动地面，亭子和屋子摇撼着，果然看见一道光照耀着亭园和屋宇，韦子春就收拾一下衣服下了亭子，忽然觉得有个东西蟠绕着自己的身子，冷得象冰冻一样勒得很紧，解不开。
后一夕，遂有大风雷震于地，亭屋摇撼，果见二光照耀亭宇。子春乃敛衣而下，忽觉有物蟠绕其身，冷如水冻，束不可解。
One night, there was a violent wind and thunder shaking the ground, and the pavilion and the house were shaking. Sure enough, a beam of light was seen shining on the pavilion and the house. Wei Zichun packed up his clothes and left the pavilion. Suddenly, he felt something wrapped around his body, cold as ice, and tight. I can't open it.
