Tao eventually marries the wealthier Zhang, and they have a son named Dollar. In 2014, Tao is divorced, and her son immigrates to Australia with his business magnate father. In 2025, 19-year-old Dollar no longer speaks Chinese and can barely communicate with his now-bankrupt father. And his only memory of his mother is her name.
