Bing Xin mentioned in the article My Childhood that she likes "I think of heaven and earth, there is no limit, there is no end, I am alone, and tears fall." Why this poem?

I thought of heaven and earth, with no limit and no end. I was alone, and my tears fell, Chen Ziang. When I stepped onto the stage and looked out, I saw the vast universe, which was eternal. I can't help feeling lonely, and my sadness comes from it, and I burst into tears. This article expresses the poet's frustrated situation and lonely and depressed mood in a generous and sad style. When I was a child, "I often walked alone on the beach, and when the tide came, it seemed like heaven and earth floating." "At dusk, the rest of the trumpets sounded, and the four mountains echoed. The familiar tone made me cry inexplicably. I don't feel bored, but I feel very small. " "Because there is no playmate" and so on all reflect a feeling that Bing Xin will feel small when standing alone on the mountain and looking up at the universe, and she will feel lonely and sad and burst into tears.
