During the Jianyan period of the Southern Song Dynasty (the early days of Zhao Gou's southern crossing): the Central Plains was occupied by the Jin Kingdom. Jin Wushu led the "Tiefu Tu" and "Guaizima" to pursue southward, and the people in the Jianghuai area were displaced. Yue Fei was the commander of the right army of the Jianghuai Xuanfu Division with less than 10,000 troops. He had to fight against the Jin soldiers, but also dealt with the constraints of the court leaders and factions. He was in a difficult situation - as the protagonist, he "helped Commander Yue with his skills and established his reputation with his military exploits." Provide an excellent stage.
