Yanhan Mountain Country Park Huanshan Road is a place for residents to walk, jog and ride, and it is also a resting place for the elderly and children around. There are about three or four hills, the original ecology has not been trimmed, the top of the mountain has a high water storage tank and a water pump room, some strange rocks, and a dense forest. Yanhan Mountain Country Park covers an area of 24.5 hectares and is located in the center of OCT. Since the establishment of OCT, the urban area has undergone tremendous changes, but the function of Yanhan Mountain as the "green lung" of the urban area has never changed.
