Lao Zhang, an ordinary man in his late fifties, runs a small car repair shop on a small street in this city. Every morning, he is always the first to come to the shop. After cleaning up briefly, he starts waiting for customers to come to the door. His life is as plain as water, with a wife and children who are close to each other. Although he is not rich, he still lives a stable life. On this day, as usual, he was repairing an old bicycle while chatting about his family and family affairs with Lao Wang, who was also setting up a street stall next to him.
