The Indian poet Tagore once marveled that China people "instinctively discovered the secret of things' melody". Ancient philosophers in the east and the west have explored the secrets of the universe, up and down, and worked hard. How did ancient Greek and modern western philosophers explore the mysteries of the universe? Let's not talk about it. We only talk about the wise ancient philosophers in China, who read the secrets of the universe with their unique tenacity of tacit knowledge. When running for four hours, everything is complicated, hidden, and secret. However, they are beautiful and have an eternal spirit of beauty. This spiritual beauty depends on the wisdom of human beings to reveal, express and spread, so that their light shines on the world. This can be done completely. Recently, I read an open series of essays "Nature Notes" published by essayist Yang Wenfeng in Prose Overseas Edition and a long nature note "Ah, Sunshine" published in Nanfang Daily, which was very shocking. These essays let me see the light of knowledge and wisdom. Reading Yang Wenfeng's Blue Earth, I feel the return of life and the beauty of a new life. Blue-the color of life and youth, makes all living things happy. Blue artistic conception, blue peace, how mysterious and beautiful our mother earth is! The essayist reveals the natural form and eternal connotation of blue. The sun poured down, and it met the air that cared for the earth. The author tells us the secret of the formation of blue-light with shorter wavelength, such as violet, blue and indigo, "meets" dust, ice crystals and water droplets in the air in the upper atmosphere of the earth and begins to scatter and spread-and a strange blue color appears. It is not difficult to describe blue light and associate it with art, and revealing the mystery of blue light is beyond the ability of ordinary essayists. Yang Wenfeng studied agrometeorology, and he knew the "why" in meteorology. Therefore, he can naturally give up vain lyricism, but show the essence of natural phenomena from flesh to flesh. Therefore, the author's expression and lyricism are "authoritative", "approachable and meaningful". Yang Wenfeng wrote: "We have been breathing in the vast and thick air at the bottom. In the storm season, there is always a blue sky hanging above us like a vault. Isn't the blue earth, our home, worth remembering by every life? " Yang Wenfeng said: "When I write nature notes, I pursue the integration of artistry, scientificity, sociality, thoughtfulness and readability. I write nature notes and can write ten volumes! " I was amazed at his courage and wisdom. He wrote one by one with his profound knowledge of natural science and cultural foundation. What is the Terminator Line? He analyzed the definition of meteorology: the dividing line between day and night on the earth's surface. Yang Wenfeng described it in the poet's language: "When the Terminator and his party passed by, nothing more than white silks and satins just passed by, and a black cloak brushed his face in a hurry. Things change, clouds go to Yun Fei. Day and night, everything in the mountains and rivers under them bears the grace and oppression of reincarnation. " This alternation of light and shade and yin and yang is the essence and law of the operation of the universe. "There is darkness in the light, and there is light in the darkness", which is an incisive enlightenment to human survival and destiny. Who can escape this philosophy? Yang Wenfeng's Notes on Nature, seemingly describing nature, actually describes the dialectical law of everything in the universe-a law that no one can reverse. The harmonious combination of philosophy and emotion makes people feel happy. The more you read, the smarter and more confident you are. Gan, executive editor-in-chief of Prose Overseas Edition, made a very incisive exposition on the prose of Nature: "Broad knowledge, extensive coverage, solid natural science foundation and profound literary and artistic accomplishment have enabled them to plug in the wings of science and art and roam in the world of science and art, nature and the world, thinking in images and abstract thinking." Yang Wenfeng loves prose as well as nature and science. His Notes on Nature skillfully combines the two, which embodies the brand-new artistic conception, context and knowledge of prose and is full of the characteristics of the knowledge economy era. Shortly after its publication, it was selected into Selected Works and a new Chinese textbook for senior high schools in Shanghai.
