Universe is a giant wave and mankind needs a giant breakwater: The science! It is the best jetty we ever have!

Some people are so weak that whenever they see a hammer, they immediately turn into a nail!

We must often visit yesterday to see how lucky or unlucky we are today!

In a beautiful night, under the stars, man always feels himself above the sky, beside the God!

When you do your work happily, work will disappear.

If you know the North, you know where the South is; if you know the darkness, you know where the light is! Evil is an excellent compass for the good!

Sadness is one of the best universities in life! Though bad things take good things from us, they do give us useful things as well!
