Royal Gold Rush Town is located in Yuerya Town, Kuancheng Manchu Autonomous County, Hebei Province, a key gold producing area in China and known as the "Golden Capital outside the Great Wall". The gold distribution pattern of "rock gold in the mountains and sand gold in the rivers" is typical, and the resource endowment is unique; the Yuerya Gold Mine, where the project is located, was Empress Dowager Cixi's personal mine and rouge mine in the late Qing Dynasty. At its peak, it produced 100 taels of gold per day. The old mine cave is well preserved and has a rich history and culture; during the Republic of China period, Japan frantically plundered and stole gold for ten years, stealing 150,000 taels of gold, which is a red ironclad evidence that exposes Japan's frantic plunder of China's mineral resources; the ancient mine cave is also a cave window that reveals the orogeny and mineralization of the Yanshan Mountains. It is rich in geographical and geological information and is a rich textbook that reveals the secret code of the earth.
