Deyang is a largely industrial city, with companies such as China National Erzhong Group and Dongfang Electric having major operations there.

[3] The ancient Shu civilization included present-day Deyang, which is home to the Sanxingdui relics.

[4] On May 12, 2008, a magnitude 8.0 earthquake stuck Wenchuan, roughly 100 km west of downtown Deyang, resulting extremely heavy human losses.

[5][6] School buildings in Mianzhu and Shifang were destroyed by the earthquake, leaving hundreds buried.

While the government didn't meet its initial (and ambitious) one-year plan to rehouse all victims, it did manage to mostly be successful within two years.

In the meantime, residents lived in government-provided mobile home type cities with weekly cash payments for all victims to purchase food and clothing.

[citation needed] Deyang is located in the northeastern portion of the Chengdu Plain, with the Longquan Mountains to the east lying in between the city and the larger Sichuan Basin.

[8] Deyang's urban core, Jingyang, is located on the Mianyuan River [zh], which passes under seven bridges flowing north to south.

[citation needed] The river has been widened, five of the bridges are part dams, and it has assumed the name of Jing Lake.

[13] Major ethnic minorities in Deyang include the Hui, Tibetans, the Yi, and the Qiang.

[13] The Hui people of Deyang live in a number of different areas, including along North Street (Chinese: 北街; pinyin: Běi Jiē) and the town of Xiaoquan [zh] in Jingyang District, the town of Luoshui [zh] in Shifang, and in portions of Guanghan.

[3] Other major manufacturers include Lan Jian Beer Factory & Shifang Tobacco Company.

[citation needed] Air quality is very high, due to breezes coming from the immediate east mountain ranges and large expanse of countryside.
