China Railway Corporation in 1950 restarted the construction of the Tianshui-Lanzhou Railway (354 km), now part of Longhai Railway between Lianyungang and Lanzhou, and gathered 300 Japanese former South Manchuria Railway engineers and others with their families in Tianshui, Gansu Province, to work under forced labor for this project. The railway was completed in 1952 and those Japanese workers, who were repatriated to Japan in 1953, formed Tianshui Association, a mutual assistance association.
