Sānhé

Sanhe lies east of Beijing, between the plain and the hills leading toward Jizhou. Its name means “three rivers,” traditionally referring to the Qidu, Baoqiu and Ju rivers of the surrounding district. A walled town was built here in 932 against Khitan incursions. Under the Ming and Qing, Sanhe remained a county in the capital region, its lands extending across river valleys and foothills.
