Thousands of angels, get up and sing praises for the children, children! His small body contains a great soul. What does Bing Xin express in this poem?

This sentence is the author's praise and appreciation of innocence and cherishing all new things, which shows the author's innocence, delicacy, admiration for truth, goodness and beauty, strong self-confidence and fighting spirit. Childlike heart is the hometown of adults. In children, the writer sees simple nature, sincere feelings and naive eyes to see the world and society clearly. When talking to children, you don't have to be "across the belly" like talking to adults, you can be free, "don't think" and "don't be reserved". Their bright eyes, small faces and sincere "love" are written in capital letters. Only after experiencing ugliness, abnormality, distortion, conspiracy, fraud and sin in the world can we love human childhood with simplicity, sincerity and innocence. In a society with too much suffering, childlike innocence has become the spiritual sustenance for writers to avoid secular storms, seek hope and comfort, and explore the essence beyond historical reality.
