When the sky is totally covered by the dark clouds, be strong enough to see the bright stars beyond them!

Never let a little man to sit on a big chair; that would be a big disaster!

Every man is a door; when the door is closed, just search for the key gently! Remember that every door has a key!

Let your works climb the stars; but you yourself stay on the ground!

Every leaf knows that time is very short. All life must be lived before the autumn comes!

If a railroad is bent, the train shall turn over; if a man's character is bent, he shall turn over just like that train.

If you are sure of tomorrow, there is no fool greater than you!
