When I was 14 years old, my mother finally made up her mind to divorce her father who had multiple lovers and had no savings. The unscrupulous father left after paying a small amount of poor breakup fee. My mother, who was struggling, could only take me back to my mother's hometown, City A. On the train to City A, I couldn't help but ask my question. Mom, we don't have many relatives in City A, so what are we doing there?
