The summer sunset is composed of two images, one from the sky and the other from the ground. Cumulonimbus clouds are synonymous with summer. In the evening, it causes showers and sometimes thunder. The energy is wild, and I feel the awe of nature along with its beauty. On the other hand, from an altitude of 30,000 feet, even though the sun is setting on the ground, the sunlight still remains in the sky, and I feel that the earth is a round sphere. I once again think that the world is one,think about what is happening in the world , and pray that the world will become one and be peaceful.
