Introduction to the town building: According to the records of Fangshan County: "Seventy miles southwest of the county, the three-story door of the north building of Zhangfang Street faces south. It is several feet high and the lower floor is empty. It is very dark. There is a tunnel below to the northwest. The second mile is connected to the tomb of Ren's family. According to legend, Ren is the elder of the pavilion. There is a well halfway from the lower floor to the middle floor. It is said that there is a sword tree in the well, and there is a statue of Biyuan Jun in it. The upper floor can be viewed from a distance, and the upper and middle floors are also connected to the tunnel. "The town tower built in the Ming Dynasty was destroyed by the Japanese invasion of China, and the town tower you see now was rebuilt according to its original appearance.
