Did the Japanese stay in China after the defeat of Japan?

Japanese orphans (overseas Chinese staying in China) refer to 1945 Japanese abandoned in Chinese mainland when the Japanese army retreated from Chinese mainland. The Japanese names after 1993 are: China Returnee, Residual Japanese, Residual Japanese in China (ちゅぅごくざんりゅぅにほほ).

The Japanese Ministry of Health, Labor and Welfare defines Japanese under the age of 13, who were adopted by China people when the Japanese army retreated from Chinese mainland, as orphans. However, Japanese women over 13 who voluntarily entered the northeast family to survive are regarded as staying in the northeast according to their own wishes, thus depriving the remaining women of their Japanese nationality and not being included in the aid for returning home. From 1945 to 1993 48 years later, this difference was finally eliminated, and orphans and left-behind women were taken as the aid targets for returning to China, collectively referred to as "Japanese returnees".

The Japanese government divides overseas Chinese who have left China into two categories, namely, "Japanese nationals are still Japanese" and "China nationals are still Japanese". The former refers to those who have Japanese nationality now, but came to Chinese mainland and settled in Chinese mainland before September 2, 1945, and have Japanese nationality before September 2, 1945; Or my parents came to Chinese mainland before September 2nd. 1945, I was born and settled in Chinese mainland, and I still have Japanese nationality. The latter refers to those who had Japanese nationality before1September 2, 945 and now have China nationality, and who came to Chinese mainland and settled in Chinese mainland before1September 2, 945; Or my parents came to Chinese mainland before September 2nd. 1945, I was born and raised in Chinese mainland, and now I have China nationality.

Most of the overseas Chinese in Japan are members of Japan's national immigration plan, and they are still alive: the total number exceeds 4,000, and most of them are abandoned in three northeastern provinces and Inner Mongolia.
