What is the content and ending of the TV series "Aunt Duohe"?

At the end of the war, Japan was defeated and surrendered, and a large number of ordinary Japanese nationals who were immigrated to northeast China in an attempt to implement long-term colonial rule in China were abandoned. 16-year-old girl Duo He is one of them. In the difficult escape, she escaped death by relying on her wit and instinctive desire for survival. She was put into a sack and sold to James Zhang, the second son of the stationmaster of a small railway station in Northeast China, as a "tool" for carrying on the family line. It is said that James Zhang's brother was killed by the Japanese army in War of Resistance against Japanese Aggression, and James Zhang's wife Zhu Xiaohuan had a miscarriage because of the Japanese devils, which left deep regret. Against the background of national Chou He family hatred, the involvement of Japanese girl Debao makes the whole family relationship ambiguous and strange.

After the founding of New China, the issue of Japanese women's congratulations has become not only a major emotional and ethical issue for the Zhang family, but also a huge political issue in the folk life of New China. Because Duohe is another woman who wants to refuse to rest, a rival in love who lives beside Zhu Xiaohuan, and the biological mother of the three children of the Zhang family. Her identity and status have become a headache for the Zhang family for decades. At the same time, how to cover up Tokuga's Japanese identity has become a nightmare for the Zhang family. James Zhang's solution is to let Duo He become Zhu Xiaohuan's "sister" and the children's "aunt"; Then, through continuous relocation, Tokuga's Japanese identity and abnormal family relations were covered up. This strange family combination is living in a turbulent political environment and an embarrassing economic life. For decades, Japanese-style Duohe has quietly and stubbornly influenced this family with the characteristics of "neatness and truthfulness", while Zhang Jiaren, such as Zhu Xiaohuan, has changed Duohe with the life philosophy of "taking things as they are" and "taking things as they are". The cruel, helpless and attractive life makes them an inseparable family because of their kind nature. The family is United and the children know who their biological mother is. Doga didn't go back to Japan and stayed in China.
