What do you think of those teachers who talk too much?

The sixth grade math teacher, whose Mandarin is not good, always plays a few jokes in class. At that time, in class, he talked about a problem about domestic garbage. He read Life, and the whole class burst into laughter. It was graduation ceremony and my math teacher gave a speech. He said "primary school students" and read "small-blooded students". Oh, my god, it's not. And he said the word seriously, which is even funnier. At that time, while eating, the classroom was noisy. The math teacher said, "I'll talk to the men, but in Buddhism, all the men give me out." Teacher China is laughing.
