Do not hide your ignorance, because somebody might help you! Hiding always prolongs the problems.

The Sun after the rain is much beautiful than the Sun before the rain!

If there were no mountains, humanity would be much lazier! Challenges make people hardworking!

Our green valleys will be greener once we fully grasp the infinite vitality of the green!

A gate to nature is a gate to heaven!

In matters of climbing long staircases, how many stairs there are is not as important as how strong a will you have!

The world may not care about you! Cope with this fact! Stand strong like a rock! Keep walking; the road to happiness will mysteriously appear before you!
