Introduction to the military arsenal site: During the Anti-Japanese War, there were two factories of the Eighth Route Army Shandong Column Arsenal in the mountains. Among them, there was a woodworking workshop in Wanglingguanzhong, specializing in the production of gun butts, grenade handles, ammunition boxes, etc. In June 1939, the arsenal was discovered by the Japanese invaders and suffered a devastating disaster. All the buildings in Yingxian Temple were razed to ruins. Taoist priests Wang Yuanxiu and Liu Mingren of Yingxian Temple refused to surrender in order to protect the equipment buried in the arsenal, and died tragically under the bayonets of the Japanese army. , known as the "patriotic Taoist".
