Pingfang District

Pingfang District is a district in the outskirts of Harbin, China (in the 1930s and 1940s a part of the Japanese puppet state Manchukuo). It was the headquarters of the Japanese Biological Warfare Unit 731 during the Japanese invasion of China and World War II. It had an airport, railway and dungeons. Most of Pingfang was burnt by the Japanese to destroy evidence but the incinerator where the remains of victims were burnt remains and is still in use as part of a factory.

Pingfang is an industrial center of Harbin now. Hafei (a factory producing helicopters, small airplanes, minivans, and cars), Dongan (a factory producing aircraft and automobile engines), and Northeast Light Alloy Processing Plant are the three major manufacturers there.
