Yuyuantan Park is one of the eleven parks in Beijing, located in Haidian District with convenient transportation. The east gate is adjacent to Diaoyutai State Guesthouse; the west gate is across the road from the CCTV Tower; the south gate is just north of the China Millennium Monument, and the north gate is connected to the Navy General Hospital. As early as the Jin Dynasty, Yuyuantan Park was a scenic tourist destination in the northwest suburbs of the Jinzhong Capital; in the Liao and Jin Dynasties, the river here was winding and a water town scenery. There are scenic spots such as "Yangzun Linquan" and "Fishing Hequ" where feudal scholars pursued seclusion and elegance. In the 38th year of Qianlong in the Qing Dynasty, the famous Xiangshan River Diversion and Water Control Project excavated the Yuyuantan Lake System, and sand birds and waterfowl gathered here, making the refreshing scenery of abundant water and lush grass full of vitality. In 1960, the Beijing Municipal Government officially named it Yuyuantan Park and designated it as an AAA-level scenic spot. The park is 1,820 meters wide from east to west and 1,106 meters long from north to south. The total planned area is 136.69 hectares, of which 61 hectares are water areas and 74.44 hectares are built green areas (including lawns). The green coverage rate reaches more than 95%, and there are about 199,500 plants of various kinds in the park. At present, the main scenic spots of Yuyuantan Park are composed of the cherry blossom garden in the west, the water diversion lake scenic area in the north (partially built), Zhongshan Island in the south, and Liuchun Garden in the east. The unique environment and the relatively small history of large-scale construction in modern times have created a natural and wild style with poplars and locust trees on the mountains, weeping willows on the banks, and lush water plants by the lake. The "Cherry Blossom Viewing Party" held in Yuyuantan Park every spring is well-known in China. The "Cherry Blossom Garden" with more than 2,000 cherry blossoms is covered with red clouds and red snow in the spring breeze, and the crowds of people watching the flowers are like spring water, which has become a unique scenery in early spring in Beijing. Fitness activities such as winter swimming in the 1970s and 1980s and the "Anti-Cancer Life Park" in the 1990s are also widely known.
