One day, I was playing with the polygonal prism at home, and I was delighted to discover that any colorless object could turn into colorful colors under the polygonal prism. Only then did I realize that many ordinary things in the world contain great beauty. The key is to be good at discovering it with our eyes. On Sunday, I went to the vegetable market to buy food for tonight. The weather was clear and cloudless. The streets were very lively with people coming and going. As I walked, I saw a cleaner wearing work clothes, with beads of sweat on his face, pushing a garbage truck forward. Suddenly, a very fashionable girl appeared, wearing a blue short skirt and a pair of red high heels. Her hair was curled up, exuding a refreshing fragrance, and she was holding a sun umbrella in her hand. He was walking towards the cleaners with great pride.
