Introduction to the Anti-League Site: The Anti-League Site is located at an altitude of one thousand meters. It was a right-click base created by Yang Jingyu, then commander of the Independent Division of the Northeast People's Revolutionary Army, in accordance with the instructions of the Manchuria Provincial Committee of the Communist Party of China. This was one of the strong bases for persisting in guerrilla warfare behind enemy lines in the Northeast Liberation War. It was once hailed by the Northeast Military Region as a bright light behind enemy lines in Liaodong. Today, ruins such as stone shed caves, house frames, stone mills, bunkers and underground tunnels still remain in the base area.
