What does Li Ji's narrative poem Wang Gui and Li Xiangxiang describe?

Wang Gui and Li Xiangxiang describes the joys and sorrows of a pair of poor young farmers, Gui Wang and Li Xiangxiang, in their love and marriage during the Second Revolutionary Civil War. Poetry combines the description of love with the expression of class struggle. Unable to pay the rent, Wang Gui's father died under the lash of the landlord, Mr Cui. He was adopted by the Li family and fell in love. At that time, the agrarian revolution led by the production party was developing here. In order to occupy it, the dissolute and shameless Mr. Cui used his revolutionary activities to arrest him and wanted to kill him. Li Xiangxiang informed the guerrillas, rescued Wang Gui, and they got married. After the guerrillas moved, Mr Cui took Li Xiangxiang. King Gui and the guerrillas drove away the White Army and rescued Li Xiangxiang. At the end of the long poem, the theme is "Let's make a revolution, and the revolution is for us". Long poems not only describe the love life of young farmers, but also render the magnificent momentum of the agrarian revolution, showing the unity of the personal fate of the oppressed and the revolutionary interests. It is a magnificent epic of the peasant revolution in northern Shaanxi.
