After the exam, we were all busy packing and selling the papers, which cost 30 cents a catty. A student with a good economic mind went to the dormitory of senior two to sell textbooks, each of which cost 3 yuan. It didn't take long for him to carry the book back despondently.

Because a schoolmate spread the news that he usually took the centenary exam, everyone shook their heads and stopped buying. Those who learn well have textbooks, those who learn badly don't need textbooks, and those who can't get on or off don't like his grades. Then we sold more than 100 yuan together and had a farewell dinner.

There is also a paper thrown by others from the fourth floor, and then the security guard followed the name on the paper to arrest people. He picked up his paper in full view.
