Introduction to the bronze bell of the Tang Dynasty: There is a round well in the middle of the house, opposite to the bell hanging on the second floor. There are stairs along the north wall leading directly to the second floor. The second floor is a wooden structure, with doors on all sides connected to the surrounding wooden railings. The upper floor is ventilated, light-transmissive, and protected from sun and rain. The bronze bell is hung on a thick wooden frame in the center of the building. The bell is 2.9 meters high, 1.56 meters in diameter, and 15.5 centimeters thick. There is no inscription on the body of the clock, and its shape is simple, dignified and generous. The bell in the bell tower is integrated with the tower, and the center of gravity is on the bell. If the bell falls, the tower will be destroyed.
