Introduction to Yifeng City: The year Yifeng City was first built is unknown, but it was repeatedly built and destroyed due to frequent wars. It covers an area of ​​nearly 500 acres, in the Dragon Vein City of Shenlong Mountain, with many spiritual creatures and wonderful scenery, and excellent Feng Shui. Large and small, solitary and abrupt boulders constitute the magnificent wonder of Yifeng City. Above the boulders, the city walls are lined with watchtowers, and under the boulders, surrounded by green trees and farmhouses, it seems peaceful. The name of Yifeng City comes from the ancient legend. "Yi" is one of the nine sons of the Dragon King, and his main food is tigers and leopards. Back then, the Ba people named their castle after "Ni" in the hope that the beast could protect their castle, expressing their longing for peace and happiness.
