In the 14th year of Tianbao, An Lushan rebelled in Fanyang, and "An Shi Rebellion" broke out. In order to escape the war, Li Bai had to flee to the south. During his exile, Li Bai witnessed the scenes of sorrow everywhere and people's misery, and wrote works reflecting social reality, such as Battle of the South of the City, Roaring Tiger and Running on the Road.
