This is a poem describing the summer scenery in the countryside. The whole poem is: "Plums are golden and apricots are fat, wheat flowers are white and cauliflower is rare. No one has ever crossed the fence, only dragonflies and butterflies fly. " After the first two sentences describe the beautiful scenery of the rural areas in the south of the Yangtze River in early summer, these two sentences describe the busy farming in April in the south of the Yangtze River. It is precisely because farmers work in the fields early and return late that no one passes by the fence during the day, only dragonflies and butterflies are flying through. This technique of profile description can be used for reference in writing.
