I don't know what "fast" means, but I feel a whistling wind blowing in my ear. At this time, I stood on the brightly lit platform, facing the subway that passed in a hurry. Phantom of light, eternity. I don't know what "slow" means, but I feel that the pink and willow green in front of me are leaving me bit by bit. At this time, I was standing beside the fisherman who was rowing leisurely, and there were slender waves under the boat. A thousand years in the world, such as my moment. What was the old age I experienced? It seems that "fast" is the present, and "slow" is just a memory. I can slowly look through the yellowed old photos, but I can't keep the hour hand and stop it. It seems that "fast" is reality and "slow" is romance. Without bread to fill your stomach, hunger will flood in an instant. Roses are fragrant, and sweetness can always cover up the passage of time. It seems that "fast" is science and "slow" is more suitable for literature. With the prosperity of machines, people's growing material needs are constantly met, and good articles are spread on paper with ink. "Fast" and "slow" are actually the left and right banks of the Seine River in Paris. There is the hustle and bustle on the right bank and the relative leisure and tranquility on the left bank; There is prosperity and luxury on the right bank, but vicissitudes and simplicity on the left bank; There is lightness and happiness on the right bank and dignity and sadness on the left bank. The right bank is the epitome of life, and the left bank is the endorsement of art, so seems my life. "Fast" and "slow" are like two shadows that don't disturb each other. One is always running and chasing, and the other is always wandering. Sometimes, I will hold my textbooks in my arms and shuttle through various laboratories, dealing with curly paper tapes, tireless electromagnetic dot timers, cold test tubes and unfamiliar and emotionless chemical reagent labels. Sometimes, I linger on every page of the book, holding my chin, and meet Tang poetry and Song poetry, politics, economy, cultural philosophy, the Three Kingdoms, the Jin Dynasty and the Southern and Northern Dynasties. I blew the wind chime of life, and "fast" and "slow" collided with each other, making a pleasant sound. The shadows of "fast" and "slow" are like an overlapping and endless relay until the flowers on the other side fall and bloom on the other side. In a complex and repetitive world, a little me will be at a loss and feel at a loss. On which side of the scale should my heart be placed? God smiles when human beings think. In the laughter of the waves rolling like the sea, I seem to hear the answer. Life is a mess, and I can find a balance. Let it be fast when the rhythm is fast, I will adjust the rhythm and let my mind carnival completely; If the rhythm is slow, let it be slow. I will relax and relax freely, so that my mind can have a comfortable rest. I don't need to ask for anything, I don't need to chase anything, I don't need to give up anything, I just want to be an ordinary and happy person, and I only live fast and slow. Life is fast and slow, and there are pleasures and leisure. Come on, in the blink of an eye. Slow down, get rid of water poverty, and then sit and watch the rising clouds.
