Is Lin a daughter?

Lin has lived in Red Star Welfare Home since he was a child. His biological father is the park ranger Lin Zhaosheng, but Lin Zhaosheng doesn't know that Lin is his own daughter. When crossing for the first time, Lin looked for Lin Zhaosheng many times and wanted to recognize him, but Lin Zhaosheng ruthlessly drove her away.

Lin grew up in a single-parent family, and his father Lin Zhaosheng was an open-minded accountant and folk mathematician. She has a strong interest in mathematics, but after several setbacks, she realized that she was short of talent and began to be afraid. In life, she is swayed by considerations of gain and loss, and only makes the most important things and the safest choices, even if such a life goes against her heart.
