《太平广记·卷十三·神仙十三》
后来有一只白鹤飞来，停在郡城东北的城楼上，有人用弹弓打那白鹤，白鹤就用爪子抓楼上的横匾，爪子的印迹好像是写下的漆字，大意是： 城还是旧城，人已不是原来的人了。我一万八千年回来看一次，我是苏仙公，你为什么要用弹弓打我呢？ 
自后有白鹤来止郡城东北楼上，人或挟弹弹之，鹤以瓜攫楼板，似漆书云：城郭是，人民非，三百甲子一来归，吾是苏君弹何为？ 
Later a white crane flew over and stood on the city tower in the northeast of the county city. Someone used a slingshot to hit the white crane. The white crane scratched the plaque on the top floor with its claws, and its footmark looked like it wrote in paint: the city was still the same but the people were not. I come back every 180,000 years. I am Su Xian Gong, why did you hit me with a slingshot?
