No one is more unlucky than the man who has never had misfortune, because he has never had the opportunity to test his abilities. --------Seneca

Or fold your hands and let the flowing water turn into a lake, or split your body and let the waterfall hang upside down in front of the river.

The mountain stands humbly and silently, silently enduring the pain and pain of the wind and sand of time. Human beings' presumptuous actions brought him frustration.
