《后汉书·本纪·显宗孝明帝纪》
日月迫近相食，彗星见天，水旱不时发生，粮食歉收，人民没有隔夜的余粮，下面忧愁聚积。
日月薄蚀，彗孛见天，水旱不节，稼穑不成，人无宿储，下生愁垫。
The sun and moon are approaching each other and eclipsing each other, and comets are seen in the sky. Drought and flood occur from time to time, and the harvest is poor. The people have no food left for the next day, and their sorrows are accumulating below.
