Introduction to the ancient city: During the Ming and Qing Dynasties when wars were raging, the ancient city of Qianzhou once supported the "Great Wall of the South" together with the ancient city of Fenghuang, leaving behind the saying that "the city of Qianzhou and the soldiers of Fenghuang" were left behind. The city still retains the characteristics of the former defense system, and military place names such as "First Fort", "Second Fort" and "Third Fort" are also used outside the city.
