The ancient city of Phoenix was built in the Yuan and Ming periods. At that time, it was the seat of the Wuzhai Chief Executive's Department. The current North Gate City Building was built in the Ming Dynasty. During the Ming Jiajing years, there was a Phoenix Direct Li Hall, where the hall pass judgment, the general soldier and Chen Xuan Yongjing Bingbei Road are all set up. In 1556, Jiajing converted the original earth city into a brick city.

The city buildings were built. The east gate was called "Shengheng Gate". South Gate - "Jinglan Gate", West Gate called "Zhuocheng Gate", North Gate for "Wall Huimen".
