Requesting a movie about the abandoned babies in China after the defeated Japan

Is Siqin Gaowa from "The Day I Farewell Hiroshima" also included, playing the role of a mother who adopted a baby girl? The heroine's name in it is Takeda Shigeko. She seemed to have been adopted twice. Siqingaowa played the mother who adopted her for the second time, and the father who adopted her seemed to be a hero. Shigeko carved the name of her brother in Japan - Takeda Hideo - on the wooden bathtub at her adoptive mother's house. Later, her brother found her and she went back to Japan. Her adoptive mother was very sad. She seemed to have taken a knife to dismantle the bathtub? Later he returned to China.

PS: I watched this show when I was very young, and I can only remember the general plot. There may be some confusing memories, please refer to them.
