《宋书·志·卷三十二》
汉代哀帝、灵帝之时，也都有这种妖异出现，而那时妖树人的形貌全都具备，所以那时出现的祸害也就大。
汉哀、灵之世，并有此妖，而人貌备具，故其祸亦大。
In the reign of Emperor Ai and Emperor Ling of the Han Dynasty, there were also such strange phenomena, and at that time, the characteristics of the monster tree were complete, so the disasters that appeared at that time were also greater.
