Youyou lost her voice at age five, and her mother, Jiang Ziwei, raised her alone. In kindergarten, she was often bullied by a classmate boy and told she had no father—while the boy's father was actually Youyou's biological father. In public, he only acknowledged that child, turning a blind eye to his own biological daughter. The first sentence Youyou spoke was unexpectedly saying she didn't want a father. Ziwei was heartbroken and disillusioned, resolved to get a divorce and start a new life raising her daughter alone. Years later, she brought up her healthy and cheerful daughter better and better, while that man was left with nothing but regret for the rest of his life.
