Inspired by the life scene where the mother put the child to sleep, the poet thought that the blue sky and the stars, the sea and fish, the garden and flowers had similar relationships, and was inspired to write the poem Cradle. The appearance of images such as "blue sky", "sea" and "garden" suddenly broadened the artistic conception of poetry and enriched the color of poetry. The freedom of space and the profusion of colors are very easy for people to imagine and reach the wandering and meaningful realm. In the poem, "blue sky", "sea", "garden" and "mother's hand" appear as static images, like a close-up, advancing from far and near to readers one by one, which is large and quiet, big and beautiful. Although "cloud", "wave", "wind" and "song" appear as dynamic images, the word "light" after them softens their dynamics. The word "gentleness" enabled them to complete the mission of setting off a quiet atmosphere. There is movement in stillness, and stillness is quieter because of movement. The combination of movement and stillness creates a peaceful, warm and quiet environment.
Poetry is one of the modern art forms, with images as the core, lyrical, concise and rhythmic. The vast majority of excellent poems come from life, which is the philosophical sentiment extracted by poets from life.
