Hailun

Hailun is a city in west-central Heilongjiang province, People's Republic of China. Administratively, it is a county-level city under Suihua City.

Before the Qing dynasty
Hailun was one of the earliest centrally governed counties in Heilongjiang Province. The city was named after the Hailun River, which runs through it. The name Hailun is a variation of a Manchu word that sounds like "kailing", which means "otter". This name was chosen due to the abundance of otters inhabiting the nearby river. The area around Hailun was initially ruled by the Manchu people and was administrated from Hulan City for much of the Manchu Qing dynasty.

Qing dynasty
By 1885 (the eleventh ruling year of the Emperor Guangxu of the Qing dynasty), Hailun was administrated by the prefecture-level city of Suihua. In 1898, the Tongken Deputy Metropolitan Government was established, and the territory of Hailun County was placed under its jurisdiction. The Tongken Deputy Metropolitan Government was dissolved in 1906.

Republic of China
In 1912, Republic of China's first year in power, Hailun Prefecture was renamed to Hailun County.

On August 15, 1945, Manchukuo was liberated by the Soviet Red Army, and the puppet state was disestablished. The region was then handed over to the People’s Liberation Army under Mao Zedong. Under the leadership of the Chinese Communist Party, the People's Government was established in Manchuria in November 1945. Hailun County was under the direct jurisdiction of the CCP and the PLA until the founding of the People's Republic of China in 1949.
