Rich people immigrated to Japan during the Republic of China.

1946, a large number of Japanese were repatriated by the Republic of China, and they returned to China by boat from Huludao. Finally, there were more than 4,000 Japanese immigrants in Northeast China, mainly Japanese women and children. Some Japanese women are married to local farmers in China and have children. Japanese children were taken in by farmers in Northeast China and survived in China.

From 65438 to 0972, Sino-Japanese diplomatic relations were normalized, and Japanese immigrants living in China went to Japan to recognize their relatives. At this point, 300,000 Japanese immigrants in Northeast China, except a few who stayed there and became descendants of Japanese, mostly died in battle, starved to death or fled back to Japan.
