Introduction to the ancient royal road: There is an ancient winding road from the main road west of Zhongjun Zhang, about 550 meters long. Legend has it that Song Zhenzong and Qianlong both passed through this road when they came to the Chinese military camp, so it was called the Ancient Royal Road. The quaint old stone steps winding through dense forests of pine and locust trees, accompanied by the flowing water in the valley, make people feel refreshed.
