The June sun in H City is very hot, and Wang Qiong is wandering around the community with a cigarette in her mouth. After a serious illness five years ago, my wife submitted a divorce agreement and now I share a two-bedroom apartment with my old mother. At the fork in the road, a man rubbed his hands and asked for one yuan to ride on the bus. Wang Qiong bought two bottles of water in exchange for change and handed it over. It's hot, drink some water. He didn't know that one dollar could buy a life.
