Introduction to Yanwang River: There is a small river at the foot of Ghost Face City called Yanwang River. According to legend, it was a river where Zhu Di, the founder of the Ming Dynasty, fled when he was young. The river is narrow but famous, and it is an indispensable attraction in Stone City Park. When the park was renovated, the famous Yanwang River landscape was also cleared from the historical cover and brought to light again, becoming a lush clear stream on both sides. Whether viewed from a distance or from a short distance, the city wall with weeping willows, green water and green trees is an excellent scenery.
