Main advantages:
Yuzhou is one of the main areas of the Yellow Emperor's activities. There are a large number of rock paintings, Shichengbao and megalithic cultural remains on the Juzi in Yuzhou, and ancient books record them as the remains left by the activities of the Yellow Emperor.
During the Yao-Shun period, Yuzhou was called Xia (the title given by Emperor Xia Zhe), which was the main area of Xia tribe activities at that time. Dayu, the leader of Xia tribe, was sealed in Xia for his meritorious service in water control, and was called "Xia Yuguo" in history. "Notes on Water Classics" records: "After crossing the old city of Yangzhai (Yuzhou), it was sealed here, which is the old country of summer."
