The ending of the most familiar Stranger movie Bao Beier is when Ding Jingya tells Chen Bing her secret, and Chen Bing is extremely regretful. Siqi's crying in front of the hospital bed awakened Ding Han, but he left silently.

Plot summary

Photojournalist Ding Han originally had a happy family. His wife Yin Yin was beautiful and virtuous, a yoga instructor, and his four-year-old son Beibei was lively and cute. But this happy family was disintegrated on a rainy morning. Yin Yin and her son were driving out and got into a car accident. Unfortunately, they died and Beibei was also seriously injured.

Misfortune never comes singly. During the rescue process, Beibei was diagnosed with acute lymphoblastic leukemia. However, the blood test results showed that Beibei was not Ding Han's biological son. Ding Han couldn't accept this fact. He and Yin Yin had always been in love. He saw with his own eyes how the child Yin Yin gave birth to in ten months of pregnancy was not his own. He wanted to explore this secret.

Ding Han suspected that the hospital had given birth to the wrong child. Doctor Yao, who delivered Yin Yin, reminded him that he must first determine whether Yin Yin was the child's biological mother. But the answer given by the paternity test is yes.
