Wang Gui and Li Xiangxiang describes the joys and sorrows of a young man and woman during the Second Civil Revolution. Li Ji, a poet, described the love course between Gui Wang and Li Xiangxiang, a poor boy, which was combined with the liberation struggle of farmers and even the whole society, so it was epic to some extent. The whole poem adopts the form of northern Shaanxi folk song "Xin Tian", which can be said to have created a new atmosphere in poetry. The extensive use of the technique of comparison is the characteristic of "believing in heaven". There are two sentences in the section of "Faithfulness in Heaven". The first sentence is a metaphor for things, which attracts interest. The second sentence says things directly, expresses feelings or makes sense. For example, "Beautiful Flowers in Shandandan" is a comparison between Xing and China, and the latter sentence praises talents, while "Good Winter Snow" means that talents are good. The metaphor in the poem is wonderful and appropriate, full of life breath, which increases the vividness, expressiveness and local color of the language.
