In the second year of Yuanfeng (1079), the new party He Dazheng, Shu Tan and others said that Su Shi slandered state affairs with poems. In August, Su Shi was arrested and imprisoned, and many people were involved, resulting in a famous literary prison in history. Due to the rescue of Zhang, Fan Zhen and others, he was released from prison at the end of1February and exiled to Huangzhou.
Ding Fengbo was written in the fifth year of Yuanfeng in Song Shenzong (1082), the third year after being relegated to Huangzhou. It directly describes the scene of rain on Shahu Road, but it shows Su Shi's situation and mood after he was relegated to Huangzhou, so the author is "single-minded" in his artistic creation of this word, which means one thing and another. In this whole conception, although one is natural scenery and the other is social personnel, "eye view" and "mind" must have the isomorphic relationship of similar association and communication. In Dingfengbo, the ups and downs on Hu Sha Road are isomorphic to Su Shi's official career experience, and Su Shi's feelings when he met on the road are isomorphic to his feelings after being demoted. All the meanings and feelings of Ci are contained in this series of isomorphic relationships.
