Second Great Uncle led the kids from the swim team around a bend to a shallow part of the river behind a grove of trees. He said: “Kids, Chairman Mao tells us to train ourselves in big rivers and seas, and you should listen to Chairman Mao. Come on, I’ll teach you!” “Xi-li hua-la!” The children were thrilled and jumped into the water. They followed Great Uncle and learned how to kick and dive, just like a big duck leading a bunch of little ducklings.
