Changchun
Changchun is the capital and largest city of Jilin Province in China. Lying in the center of the Songliao Plain, Changchun is administered as a sub-provincial city, comprising 7 districts, 1 county and 3 county-level cities. According to the 2020 census of China, Changchun had a total population of 9,066,906 under its jurisdiction. The city's metro area, comprising 5 districts and 1 development area, had a population of 5,019,477 in 2020, as the Shuangyang and Jiutai districts are not urbanized yet. It is one of the biggest cities in Northeast China, along with Shenyang, Dalian and Harbin.

The name of the city means "long spring" in Chinese. Between 1932 and 1945, Changchun was renamed Xinjing (Chinese: 新京; pinyin: Xīnjīng; lit. ' new capital ') or Hsinking by the Kwantung Army as it became the capital of the Imperial Japanese puppet state of Manchukuo, occupying modern Northeast China. After the foundation of the People's Republic of China in 1949, Changchun was established as the provincial capital of Jilin in 1954.

Known locally as China's "City of Automobiles", Changchun is an important industrial base with a particular focus on the automotive sector. Because of its key role in the domestic automobile industry, Changchun was sometimes referred to as the " Detroit of China." Apart from this industrial aspect, Changchun is also one of four "National Garden Cities" awarded by the Ministry of Construction of P.R. China in 2001 due to its high urban greening rate.

Changchun is also one of the top 40 cities in the world by scientific research as tracked by the Nature Index according to the Nature Index 2020 Science Cities. The city is home to several major universities, notably Jilin University and Northeast Normal University, members of China's prestigious universities in the Double First-Class Construction.
