The former site of the Japanese Consulate General in Harbin is a small yellow building on the second floor of 108 Red Army Street, and is now the Harbin Railway Foreign Economic and Trade Company. Seventy or eighty years ago, this beautifully-shaped building served as the Harbin office of Nanman Railway Corporation and the Japanese Consulate General, the largest colonial invasion agency of Japanese imperialism against China and the magic cave of the anti-loggers. The Harbin Office of Nanman Railway Co., Ltd. was changed to the Japanese Consulate General in Harbin in 1936. Its function has also changed. According to the information, the building has a special high-level police department, which is a special service system of the Japanese Foreign Ministry. At the same time, a basement detention center that can accommodate more than 100 people has been established. It is a historical witness to Japan's aggression against China.
