The teacher tells daodao to be good on his first day at school. He tells him that he must pay attention to class. He says that even if he had learned this before he still had to pay attention. The teacher says that if the teacher mistakes, he should not be angry with the child. He then says that the final answer is 666, and that the teacher should continue the class anyway. He asks why he feels a sudden chill in his spine, and the answer is that he made a mistake. It should have been 66.6, but it is still wrong. He wonders why the teacher is bleeding from staring at him so hard, and he realizes that it is 2333, which is the answer to the question, "what is going on?" He then wonders what he did wrong in his past life, and what he would do if he were to make the same mistake in the future. He concludes that he is just a pitiful young bald man. He goes on to say that regardless of what a teacher does when he makes a mistake, he would always sleep in the class. For a while, he becomes a nightmare to all the teachers in the office. The next period is "the evil kid" , and they would stare at him with death stare. He thinks that the focus of the school is "controversy, so is "marketing" . This is the inevitable downfall of event marketing, he says. He will do it again, and so on.
