The story begins after the surrender of the Japanese army in 1945, and the Japanese evacuated from China. Yoko Takasaki gave her daughter Photon to Mrs. Chen, and Mrs. Chen gave her bracelet to Yoko Takasaki as a token, so that she could use this bracelet to retrieve her daughter in the future. A few years later, Yoko Takasaki sent a bracelet to retrieve Photon who was renamed Chen Xiulan, and separated from her brother Chen Jianhua. Decades later, when the Cultural Revolution began, Chen Jianhua was severely attacked because he had a Japanese sister. In 1975, Chen Jianhua was reformed in the cadre school, but he was transferred back because of some tasks. He came to Japan and recognized her sister Xiulan, but he was afraid that everyone would think she was a Japanese spy, so he avoided Xiulan, but Guangzi felt that Chen Jianhua was very familiar and was very excited, but he overheard him talking to her. The wife had a conversation and learned that because of her status, many people looked down on her, so she left Guangzi sadly, and finally returned to Mrs. Chen's house, quietly left the bracelet and left. In the end, the Gang of Four was finally smashed, and Guangzi came to China to reunite happily with his mother
