Among them, I like the metaphor describing the sky best, which makes me intoxicated in this article. It says: The sky is extremely bright blue, and only a few light clouds like tulle stick in the air, just like a girl in a beautiful blue summer dress with a thin white scarf around her neck. Do you feel that I am there, and the description of the swallow is vivid, which makes people seem to have come here to witness everything. Although "hearing is false, seeing is true", I don't think so. After reading such a good article, I really feasted my eyes today.
Today, I finally realized a sentence from Helen Keller: "Others say that knowledge is power, and I think knowledge is happiness."
