1. The first time I met Yu Zijiang was at a math tutoring institution. The math teacher picked up the book fiercely and shouted: "Yu Zijiang, if you have to write physics problems, go home and do it. Don't disgust me in my math class!" The boy blew a loud whistle and said with a smile in a ruffian voice: "Thank you, teacher, for not killing me!" And then walked out swaggeringly.
2. The second time I saw him again was already in the first year of high school. Xi Mi was about to go to the bathroom with his friends. As soon as he arrived at the door, he saw a familiar figure standing at the door of the classroom with a math book on his head, his face full of dissatisfaction. The math teacher of his class was furious, "If you write physics problems in math class again, you will call your parents to the school!"
3. The third time was in the class teacher's office. They were standing together against the wall. The class teachers of the two classes hated the iron and said, "You two can't be brothers and sisters. One always writes math problems in physics class, and the other always writes physics problems in math class!"
4. Many years later, at a seminar, the famous physicist held the hand of his mathematician and asked softly in her ear: "You wrote math problems in physics class back then, so you could come into the office with me to arouse my ideas. Tsk, tsk, tsk, you really do whatever it takes to get me!"
