The year my son was diagnosed with a serious illness and faced huge medical expenses, my husband Fu Li had a car accident and lost his job. I divorced and abandoned them, taking only my six-year-old healthy daughter. Five years later, my genius son graduated from college and was admitted by the Chinese Academy of Sciences. Fu Li had become an upstart in the business world by then. He accompanied him to academic lectures. In the conference hall, professors chatted and joked. Who would I most like to see such an achievement today? My so-called biological mother, or my sister.
