After reading, I learned that words and words alone are not good or bad, but when they are connected into sentences or chapters, they have opinions and tendencies. I used to say that literature is like firewood, rice, oil, salt, sauce, vinegar, and tea. Now it seems that literature is like the bricks, tiles, steel bars, and cement materials of high-rise buildings. Without chefs and cooks, we can't cook delicious food; without engineers, designers, and craftsmen, we can't build buildings. The more books I read and the more articles I read about teachers, especially the experiences of online teachers, the more I feel that I don't know blueprints or recipes and can only be a diner tasting delicious food; I am also a caregiver who cares for flowers and plants, fertilizing and watering them, and casually watching flowers and grass in my free time. It is also a pleasure.
