Introduction to Dongluo City: Dongluo City was built in the 12th year of Wanli in the Ming Dynasty (1584). Today, the gate of Dongluo City still exists, and there are two small gates in the north and south, commonly known as Nanhanmen and Beihanmen. At present, the South Gate is passable, and the North Gate has become a factory building and a water gate. They are basically intact and are located on the east side of the two North and South Gates.
