# Jianyang, Sichuan

Jianyang (simplified Chinese: 简阳; traditional Chinese: 簡陽; pinyin: Jiǎnyáng) is a county-level city under the administration of the prefecture-level city of Chengdu, in Sichuan Province, Southwest China. Situated only 48 kilometers (30 mi) from Chengdu, Jianyang is administratively under the jurisdiction of Chengdu, changed from being a prefecture-level city of Ziyang since May 2016. The preparation work for changing it to "Jianyang District" is already started as of August 2019. The urban center is located on the banks of the Tuo River.

## History

Jianyang has a recorded history dating back over two thousand years. It was part of the state of Shu until the third century BC and was incorporated into the Qin Empire following the unification of China under Qin Shihuang.
In the Yuan dynasty, it was named Jianzhou (簡州); its current name was adopted in 1913 during the Republic of China. After the foundation of the People's Republic of China, it was incorporated into the Neijiang Administration Zone. It was divided into communes during the Cultural Revolution. When the communes were abolished, it was subsumed by Chengdu. In 1994, the county was converted into a county-level city. In 2007, the county was given broad autonomy over its budgeting and financial affairs by the State Council as part of a wider experiment. In 2016, the State Council transferred jurisdiction of Jianyang from Ziyang to Chengdu, ostensibly to increase urban integration with the provincial capital.

## Administration

Jianyang was administered by the prefecture-level city of Ziyang up until 2016 when it was transferred to Chengdu prefecture due to Jianyang's economic integration as a part of the greater Chengdu metropolitan area. Jianyang is home to commuters who work in Chengdu.
Administratively, Jianyang is subdivided into 16 subdistricts and 21 towns:
