The Star is a collection of poems, consisting of 164 short poems. Bing Xin believed in "the philosophy of love" all her life, and she thought that "with love, there is everything". In the Stars, she kept praising love. What she loves to praise most is maternal love. Bing Xin not only loves her parents, but also cherishes brotherhood. She loves her three younger brothers. In an essay she later wrote, Letter to a Little Reader XIII, she also compared her three younger brothers to three bright stars. Bing Xin praised maternal love, human love and childlike innocence. At the same time, she also praised nature, especially the sea she was familiar with as a child. Praising nature, childlike innocence and maternal love has become the eternal theme of Bing Xin's life creation. Its theme is: maternal love, nature, innocence and life. "Stars in Spring Water" is recognized as the highest achievement of the poem, and Mao Dun called it "starry sky lattice" and "spring water body". The theme it embodies is: maternal love, nature and innocence, which constitutes Bing Xin's ideological core "philosophy of love". "Stars in Spring Water" contains three aspects: one is to praise maternal love and innocence; The second is the worship and praise of nature; The third is thinking and feeling about life. Many of these works have been selected into middle school textbooks and are deeply loved by readers. "Spring Water" is a companion piece of "Stars", which consists of 182 short poems. It was first published in the supplement of the Morning Post, but the spring water came out three months later than the stars. In Spring Water, although Bing Xin is still praising maternal love, affection, childlike innocence and nature, she has used more space to implicitly express the troubles and anguish of herself and her generation of young intellectuals. She tells her feelings in a gentle and sad tone, while exploring the meaning of life and expressing her desire to know the true face of the world.
