Introduction to Guanlou: In the early years of the Ming Dynasty, Zhu Zeizi built five stone gates in Changning Village to prevent the "Zhu Zeizi" from invading. Chen Shan is from Chenjiaba under Balingtai. She has a martial arts background and is extremely powerful. In a sniper battle against the "Zhu Zeizi", Chen Shan held an 800-pound copper cannon and hit the stone mill and wooden stakes on the rolling plate at the opposite side of the Golden Duck Village. The invading enemy was so frightened that they turned around and fled. Don't dare to invade rashly. Since then, the story of Chen Shan's blocking of the Xihe River has been passed down through the ages, and local villagers raised funds to build a gate tower to commemorate it.
