"If you don't teach, it's your father's fault, your teaching is lax, and your teacher is lazy." This is a familiar saying of Saint Amethyst. And my teacher Zhang, who doesn't practice violence at all, is as kind as a kind old hen.

Everyone was so scared that they stopped talking and waited timidly for "punishment". However, Mr. Zhang did not show the earth-shattering "lion roar" and said calmly, "Students, everyone must want to know the origin and formation of tidal phenomena. Then, I will explain qiantang bore in detail. " After that, Mr. Zhang vividly described the knowledge and physical principles he had collected.

We are like sponges, assimilating every drop of knowledge. ...
