A large part of Changchun's charm lies in the Puppet Emperor Palace and the city's ski resorts. Changchun was the capital of the Japanese-ruled state of Manchukuo during its occupation from 1937 to 1945. Vestiges of the city's disgraceful past remain in the palace. Changchun boasts a few great ski resorts, among which the Songhuahu and Beidahu are the best. Changchun is also China’s film and automobile bases. Film lovers can find everything they need in Changchun Film City.
