This is an ode to maternal love. This poem eulogizes the great beauty of human nature-maternal love. In the first two sentences of the poem, the person written is mother and son, and the thing written is thread and clothes, but it points out the love of flesh and blood between mother and son. The two sentences in the middle focus on the actions and attitudes of loving the mother, showing the mother's deep affection for her son. Although there are no words and no tears, it is full of pure love, which is gripping and tearful. The last two sentences are the sublimation of the first four sentences. Using the metaphor of popular image, we pinned our fervent feelings on this naked child. How can we repay our children like maternal love and grass in spring? With fresh, smooth, plain and plain language, the whole poem is full of rich and mellow poetry, which has touched the heartstrings of many readers for thousands of years and caused thousands of wanderers to sing.
