( Essay )
People are old, have shallow nights, short hours, and poor sleep quality. I often get up before dawn. As is customary, leave the bed to go to the study to read a book for an hour, and then go outdoors to exercise. I finished my homework this morning and was ready to go, and although the weather forecast last night said it was foggy and it was not good to go out, I did not think that I would go for a walk as usual. I opened the door and sure enough, the fog came over me and poured into the living room. Wow! The white fog that filled the courtyard shrouded the auxiliary facilities of the courtyard wall, hiding me in it, out of the alley into the street, and kept walking through the fog. The familiar road trees, shops and tall buildings are all hazy, like the beginning of chaos.
I relied on my memory, like a blind man walking along the sidewalk, walking very slowly, lifting my feet low, afraid of falling and getting hurt. Occasionally, two fluorescent lights appeared in front of them, accompanied by a short whistle, but the figure of the car was not seen. I was sad, and the fog formed a barricade, making passers-by cautious to avoid accidental collisions, but inhibiting the speed of the Mercedes and affecting the trip. Look at the fog again, like a sea of clouds and mist, white and ethereal, and the smoke is spectacular. Based on his literary love, he wanted to describe this scene, but he was suffering from the lack of precise words, so he borrowed the words of the Qing Dynasty scholar Zhang Weiping: "Its white is like snow, its soft as cotton, its light is like silver, its width is like smoke: thin or like silk, thick or like blankets, scattered or like smoke, moving or practicing." The ancestors were insightful and appropriately described. Suddenly, the fog that was as calm as the tide rushed with the car, splitting the head and covering the face, making people unable to prevent it. I wondered, does the fog have power? There is such a clear direction and trajectory of movement! So, the two eyes scanned left and right, wanted to find answers from the fog, took the surrounding appendages as the entry point, found that the cold and warm currents in the building group, vertical height and the action of the forest, evolved into a cluster of white fog, attached to the trunk, climbed the branches, touched the leaves, slowly rose from the gaps, stayed on the treetops for a while, and then spread around, diffuse, just for a moment, the fog became denser and denser, thicker and thicker, pouring into the sky, covering the originally spacious mountains, and it was difficult to recognize things within a few steps. Heaven and earth are fused, and all things are shrouded, is it the fog that wants to cover up something?
No, it has no meaning, no intention, just a natural phenomenon. Because the fog does not fall from the sky, nor is it released from the ground, but the condensed water vapor in the air. However, fog is closely related to the temperature and humidity between heaven and earth. During the day, the sun shines on the water, and the water stores the heat. At night, the water will slowly release it. Therefore, the air near the surface of the water is relatively warm, while the land humidity drops quickly, and there is a significant difference in temperature and humidity until dawn or morning. When the cold air flow on land flows to the surface of the water, it presses down the air rich in water vapor and forms a large small droplet of water, forming a fog.
This fog does not last long. When the sun rose in the east and illuminated the mountains, the thick fog quickly faded, Yuyu clarified, and the urban mountain village was clearly visible. Only the mist floating on the top of the mountain, wrapped around like a python dragon jade belt, refused to fade...
