《贺雨》是白居易讽喻诗的首篇,可见诗人对此诗的偏爱。诗云:皇帝嗣宝历,元和三年冬。自冬及春暮,不雨旱爞爞。上心念下民,惧岁成灾凶。遂下罪己诏,殷勤告万邦。帝曰予一人,继天承祖宗。忧勤不遑宁,夙夜心忡忡。元年诛刘辟,一举靖巴邛。二年戮李锜,不战安江东。顾惟眇眇德,遽有巍巍功。或者天降沴,无乃儆予躬。上思答天戒,下思致时邕。莫如率其身,慈和与俭恭。乃命罢进献,乃命赈饥穷。宥死降五刑,责己 He Yu is the first verse of Bai Juyi’s allegory poems, which shows the poet’s preference for this poem. Poetry: emperor Si Bao, Yuan and three years of winter. Since the winter and spring twilight, no rain 爞 爞. On the mind of the people down, fear of disaster disaster. Then he sent his sins to all nations. Emperor said to one, following the days of ancestor. Do not worry about Qin Ning, 夙 night worry. In the first year punish Liu Pi, one stop jingba. Two years to kill Li Kui, not war Jiangdong. Gu Wei 眇 眇 Germany, 遽 a towering work. Or come to an end, nothing is bowed. Think of God on the ring, think of the next thought 邕. Moment rate of its body, compassion and frugality. It is the sacrifice of the remonstrance, but the destiny of famine. Yu died down five penalties, blame yourself
