Qu County or Quxian is a county in the northeast of Sichuan Province, China. It is the westernmost county-level division of the prefecture-level city of Dazhou.
Formerly known as Dangqu (Chinese: 宕渠), the county is best known for historic monuments. Namely, a partially preserved mausoleum complex, featuring gate towers, or que, belonging to the Shen (Chinese: 沈) family, which dates back to the Han dynasty.[1] [2]
From 2014 to 2018, the Han dynasty site of Chengba (城坝遗址) near Tuxi in Qu county was excavated. A number of eave tiles with Chinese characters "dangqu" (宕渠) have been found, leading archaeologists to believe that this was the site of the Han dynasty city of Dangqu.[3]
Qu County comprises 3 subdistricts, 28 towns and 6 townships:[4]
Qu County has a monsoon-influenced humid subtropical climate (Köppen Cwa).
