In a private school, a student was dozing off and the teacher woke him up with a ruler. After the master woke up the students, he shouted angrily, "Master can't doze off in class! If you have knowledge and skills, you will make an online connection for the teacher. If you can make an offline connection, you won't interfere with sleep in the future! " The student replied: "Good! Ok! " The master said, "Listen to me carefully. My first couplet is: big fish eat small fish, small fish eat shrimp, and shrimp drink water. Get to the bottom of it! " The student replied, "Oh, it's so simple! My bottom line must be related to sleeping! " The master said, "Yes, listen!" The student replied, "Master! My bottom line is: master presses teacher niang, teacher niang presses big bed, big bed presses the ground, and the ground shakes! "
