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 , 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 () 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 University Plan.
History
Early history
Changchun was initially established on imperial decree as a small trading post and frontier village during the reign of the Jiaqing Emperor in the Qing dynasty. Trading activities mainly involved furs and other natural products during this period. In 1800, the Jiaqing Emperor selected a small village on the east bank of the Yitong River and named it "Changchun Ting".
At the end of the 18th century peasants from overpopulated provinces such as Shandong and Hebei began to settle in the region. In 1889, the village was promoted into a city known as "Changchun Fu".
Railway era
In May 1898, Changchun got its first railway station, located in Kuancheng, part of the railway from Harbin to Lüshun (the southern branch of the Chinese Eastern Railway), constructed by the Russian Empire.
After Russia's loss of the southernmost section of this branch as a result of the Russo-Japanese War of 1904–1905, the Kuancheng station (Kuanchengtze, in contemporary spelling) became the last Russian station on this branch. The next station just a short distance to the south—the new "Japanese" Changchun station—became the first station of the South Manchuria Railway, which now owned all the tracks running farther south, to Lüshun, which they re-gauged to the standard gauge (after a short period of using the narrow Japanese gauge during the war).
A special Russo-Japanese agreement of 1907 provided that Russian gauge tracks would continue from the "Russian" Kuancheng Station to the "Japanese" Changchun Station, and vice versa, tracks on the "gauge adapted by the South Manchuria Railway" (i.e. the standard gauge) would continue from Changchun Station to Kuancheng Station.
An epidemic of pneumonic plague occurred in surrounding Manchuria from 1910 to 1911, known as the Manchurian plague. It was the worst-ever recorded outbreak of pneumonic plague which was spread through the Trans-Manchurian railway from the border trade port of Manzhouli. This turned out to be the beginning of the large pneumonic plague pandemic of Manchuria and Mongolia which ultimately claimed 60,000 victims.
City planning and development from 1906 to 1931
The Treaty of Portsmouth formally ended the Russo-Japanese War of 1904–05 and saw the transfer and assignment to the Empire of Japan in 1906 the railway between Changchun and Port Arthur, and all its branches.
Having realized the strategic importance of Changchun's location with respect to Japan, China and Russia, the Japanese Government sent a group of planners and engineers to Changchun to determine the best site for a new railway station.
