Ting Feng'er said that every girl is an angel, an angel who never sheds tears. Only later did I discover that every boy has a pair of wings, a pair of wings that cannot fly. Until they meet each other, the boy has the girl's tears, and the girl has the boy's flight. I don't know why I have such an idea. Perhaps, I really fell in love with a pair of wings, a pair of gray wings. Some people like to go outing when the mountain flowers are in bloom, some people want to look up at the stars in a quiet night, some people enjoy the comfort of walking in the rain, some people... So the mountain flowers were moved into the greenhouse and lost their vitality; the stars were finally close in front of them, but they were beyond recognition; the rainwater was sent to the laboratory, but it became synonymous with polluted gases. People love these beauties so much, but they don't know that without distance, they are nothing.
