Dou, Dou The train rang out the flute and started slowly. I clearly saw the tears of endurance in my father's eyes. After my father left, I would start my own life in this strange city, and truly survive independently. The important task of glorifying my family and ancestors at home will also fall on my head. I will live as a real urban person, realizing the city people who have been surging for a long time in my heart. It seems that the city people are old and raised their hands in a few seconds. My father will disappear from my sight with the train heading north. Suddenly I felt that I should say something and do something.
