The ending of little sister Duohe.

"Aunt" Duohe finally returned to Japan, and the children also knew that Duohe was their biological mother. Doha is a Japanese woman, but she has lived in China for more than 30 years, bearing children for the Zhang family. Her ending is open-ended. She didn't say whether she returned to Japan or divorced James Zhang.

Duohe is a Japanese woman who stayed in the northeast of China after the end of War of Resistance against Japanese Aggression. She escaped with the villagers. She was taken home by James Zhang's parents and taken good care of. Doha's identity is a mystery, but the audience with God's perspective knew from the beginning that she was a Japanese woman.

In order to repay the Zhang family for saving his life, Duo He expressed his willingness to have children for the Zhang family, so Duo He gave birth to three children. After liberation, Duohe became the child's aunt.

After the normalization of diplomatic relations between China and Japan, the Japanese government sent someone to find Duohe, saying that her mother was still alive and terminally ill and planned to take her back to Japan. At that time, Doha's children all knew that Doha was their biological mother.
