"Different angles have different results." This is a truth that Su Shi told us in "Topic Xilin Wall". Have you ever been in such a situation?

Once upon a time, a scholar went to Beijing to take an exam. He had three dreams before the exam, and then he couldn't understand it. The next day, he found a fortune teller to explain them. The fortune teller asked him: What dream did you have?

Scholar: Yesterday, I dreamed that I planted a cabbage on a high wall, that I brought a hat and an umbrella in the heavy rain, and that I was sitting on the bed with my beloved girlfriend back to back.

Fortune teller: What are you doing in Beijing this time?

Scholar: I'm in a hurry for an exam.

Fortune teller: You don't have to take the exam.

Scholar: Why?

Fortune teller: You grow cabbage on the high wall. Isn't this white? How can you grow cabbage on a high wall? You are wearing a hat and an umbrella in the heavy rain. Isn't that unnecessary? You and your beloved girlfriend sit back to back in bed, and it's over when you get to bed. Go home.

The scholar was very sad and went back to the hotel at night to pack up and prepare to go back.

Shopkeeper: Why did you leave without taking the exam?

Scholar: Because I had three dreams last night.

Shopkeeper: What three dreams have you had?

The scholar told the shopkeeper the three dreams he had last night from beginning to end.

Shopkeeper: No, the cabbage planted on the high wall is not white, but high school. You wear a hat and an umbrella in the heavy rain, which is not unnecessary, but foolproof; It's not impossible for you and your girlfriend to sit in bed back to back, but it's time to turn over. Can't you just turn over and finish it?

The scholar was overjoyed and stayed to take the exam. Sure enough, he is in high school!
