Once upon a time, there was a student who didn't study hard and forgot everything he had just learned. Mr. Wang said angrily, "You are so forgetful. I wrote the words on your face to see if you have forgotten!" " After that, he wrote a lot of words on his face with a brush. From then on, the students studied hard and later became the first prize. On the night I went home, I passed by my husband's door and wrote a couplet on the door: "I used to draw my face with ink, but now I nod." I'm very proud. The next day, Mr. Wang opened the door and saw the couplets, only to know that the students in the past had won the first prize. Now he writes couplets to vent his anger. Then take the pen and ink and add two words in the upper and lower parts. When the champion comes home. Waiting for Mr. Wang to apologize. But I haven't seen Mr Wang for several days. So he came to Mr. Wang's door. Looking up, I saw the couplet "If it wasn't the past, why did Zhu nod today?" He suddenly woke up and knocked at the door to apologize to her husband.
