Tell you a story, and you will be suddenly enlightened. At that time, you just entered the university, and the teacher told you (this story has been heard by many people):
Once upon a time, there was a poor scholar who went to Beijing to take the exam. He has failed twice before, and naturally he is uneasy when he goes to Beijing for the third time. I lived in an inn and had three dreams at night. The first dream dreamed of planting cabbage on the wall, the second dream of sitting back to back with my favorite cousin, and the third dream of wearing a hat and playing an umbrella in rainy days. The scholar panicked. He didn't know what these three dreams meant, so he went to a fortune teller. The fortune teller said, "You didn't do well in these three dreams, which means you failed in the exam! Why? It's no use planting cabbage on the wall; Back to back with your favorite cousin-no chance; Take a hat and open an umbrella-it's not necessary. How can I get in? You'd better pack up and go home! " Hearing this, the scholar was very excited and disheartened, and went back to the inn where he stayed to pack his things and prepare to go home. The scholar lived in this store for the first two exams in Beijing, and the owner knew him very well. Seeing that he was leaving, he asked, "The exam is about to begin. Why are you going home? " The scholar told a story about dreaming and the fortune teller's dream interpretation. The shopkeeper said, "I can also interpret dreams. Listen to me explain to you: grow cabbage on the wall-high school; " Back to back with my cousin-the opportunity to turn over is coming; Take a hat and open an umbrella-get ready. Doesn't this mean that you will succeed in this big exam? Hearing this, the scholar was greatly encouraged, his confidence doubled, and his heart was free from distractions. He studied hard, and as a result, the exam was over. He explored flowers in high school.
