The first day of class for new teachers

Today is a bright day! The sun is hot, and not too many clouds lie in the sky!
At 9 o'clock in the morning, the class for new teachers opened, the ceremony was started.
Although I do not want to stay here, I want to have the ability of being a teacher, to master how to delivery a speech, and I think that many years later, I will go back to university to teach my reserach and ideas!
