Brief analysis: these two poems omit the story of two children holding umbrellas that the poet saw, omit the questions in the poet's mind, and directly write the joy of solving doubts. The solution to the question may be that the poet saw the abnormal behavior of the child and began to observe and think more carefully. As a result, he suddenly realized that the two children were holding umbrellas even when it didn't rain, but waving the handle of the umbrella to let the wind blow the boat forward. You can also ask two children directly, and the children will tell him the reason. Anyway, knowing the reason, the poet must have lost his mind. The cleverness of the children and their naivety reflect the cuteness and agility of the two children.
