北京、承德、天津 Scenic Beijing-Chengde-Tianjin
Zhongnanhai is an area in central Beijing, China adjacent to the Forbidden City which serves as the central headquarters for the Communist Party of China and the State Council of the People's Republic of China.
The name of the Zhongnanhai complex, located west of the Forbidden City, means "central and southern seas/lakes", referring to two lakes (the "Central Sea" and "Southern Sea") located within the compound; it is sometimes translated as "Sea Palaces". These two lakes are part of a series of irrigation projects carried out during the construction of the nearby Forbidden City.
These three lakes (Southern, Central, and Northern Seas) were originally an imperial leisure garden, with parklands on the shores of each lake, enclosed by a wall. Most of the pavilions, shrines, and temples survive from this period. Whereas the Northern lake had a religious focus, the shores of Central and Southern lakes were dotted with a number of palaces.
