Teachers, please listen to me: you are a golden key, led us to the golden gate of knowledge. You as we slowly open the wisdom of the lock, but we are in front of the door shouting: "open the door, open the door in succession!" You tell us everything don't be impatient, otherwise will be without a single success. We waited quietly, waiting for you to open the door of that a moment. The doors finally opened, you said the sound: "children, go!" So, we will plug in the wings, flying in the ocean of knowledge.
