Confucius once said: Of three people, one can be my master. During several -year schooldays, the teachers we have met in school may be limited. After leaving school, we have to be busy in work. But it doesn't mean that we don't need to study any more. In our work and daily life, we still need to learn many things. In a word, Knowledge is everywhere. So, teacher is everywhere too. There may be someone who teaches you how to work and how to live. Although they are not called teachers, they are doing the same thing as the teachers do in school. In this Teacher's Day, please give your best wishes to those people. They should be respected as the real teachers, and they really deserve it.
