The Diaoyutai State Guesthouse (DSG) (simplified Chinese: 钓鱼台国宾馆; traditional Chinese: 釣魚臺國賓館; pinyin: Diàoyútái Guóbīnguǎn) is an ancient royal garden and modern state guesthouse-complex located on the east side of Yuyuantan Park in Haidian District, Beijing, China. Emperor Zhangzong of Jin once built a fishing platform here, thus the name "Diaoyutai", which has a history of more than 800 years. During the Qing Dynasty, the Qianlong Emperor ordered to dredge the Yuyuantan and build a palace here, which was then turned into a royal garden. The modern State Guesthouse Park was built by the government of the People's Republic of China in 1958-1959 on the basis of the ancient Diaoyutai Scenic Spot, as a place for visiting dignitaries to stay and for meetings and conferences. Diaoyutai State Guesthouse is located outside Fuchengmen in western Beijing, east of Yuyuantan, southwest of the intersection of Fucheng Road and Sanlihe Road.
