During the Hongwu period of the Ming Dynasty, Shandong moved to Jinan from Qingzhou to the Chasing Department, and used the original Jinan Fushu (address at Jinan Quancheng Middle School on Jinan Yunshu Street) as the office institution. Chen Xiu, Jinan Zhifu, converted Kaiyuan Temple (currently the address of Shandong Provincial Political Consultative Conference) to the government office in order to save people's power. The bell tower is on the "left wing of the palace" and local residents ask Chen Xiu to move the bell tower to another place. Hongwu three years (1370) July, Chen Xiu summoned more than 200 craftsmen from Zhangqiu and Zhangping. "Muwa Shiqiu, all the places are ready. In the moon, the clock tower is built, only one mile to the government, and the Drum Tower stands. The building uses the old place of Kang monk's courtyard, the third floor of the building, the fourth level of the building, the old hall, the old hall, the transfer of the Fan Wang Xiang, Changed the name to Zhen'anyuan" ("Licheng County Zhi" Chen Xiu "Zhen'anyuan Bell Tower"). The Kang monk courtyard built in the Yuan Dynasty is in the current Zhonglou Temple Bell Tower Taiji ruins and north, from now on, the folk commonly known as Zhen'anyuan is the Bell Tower Temple. Back then, the clock tower lived in the southwest of the clock tower temple, the platform was square, the edge length was 20 meters, the height was seven or eight meters, the earth was made of clay, and the outside was covered with blue brick. The three-story building on the high platform, carved beams and painted buildings, moths towering ridges, flower and Danzhu, was extremely magnificent. On the south of the highest floor of the pavilion, there is a golden word "see Nanshan leisurely". Every time the hanging bell rings, the whole city is heard. For hundreds of years, the clock tower has been in disrepair, the clock tower has collapsed before the founding of the country, the stone on the base of the platform is broken, and the trees are overgrown. A large iron bell was buckled in the middle of the platform. Many children living nearby climbed the platform and picked up the bell that was smashed by bricks and tiles. Now, the bell has been moved to Nanfeng-Mingchang Bell Pavilion. In October 2008, archaeologists in Jinan City cleaned up the ruins of the Bell Tower.
