Beacon Tower Introduction: Cuiyan Mountain is strategically located. The Jinzhou frontline command post of the Liaoshen Campaign was located in Ganniutun at the foot of Cuiyan Mountain. At that time, not only the sick and wounded of the People's Liberation Army lived in Cuiyan Mountain, but also a masonry beacon tower was built, which can be said to be an important stronghold in the Liaoshen Campaign.
