He Yin and Zhao Jianguo have lived together for decades, taking care of their families and taking care of their grandchildren. When she discovered that Zhao Jianguo had registered for marriage with someone else, her years of dedication and trust suddenly collapsed. At this time, she won the lottery prize and decided to say goodbye to the past and live independently. In order to embezzle the bonus, Zhao Jianguo and his family tried to claim a relationship through the law. He Yin defended his rights in accordance with the law and held him responsible for bigamy. In the end, the law made a fair judgment, and He Yin completely got out of the predicament and used the proceeds to establish a legal aid fund, dedicated to helping more disadvantaged women realize new values in life through self-reliance and public welfare.
