vitality on great peaks
in the picture, we cannot simply see a quite snow-covered mountain, but a mountain of vigorous life. a hard indisputable reason remains: three mountain-climbers just represent “vitality on great peaks”, which is written at the bottom of the picture.
it is those people who dare to challenge the highest peaks that deserve the most fascinating sight of life. only when you dare to burn the bridge, can you push forward whole-heartedly and win the battle wonderfully. only when you are willing to leave the clam life of dwelling on your quiet farm, can you appreciate the overwhelming beauty of surging billows, which will inspires you to find the true meaning of life. and the true meaning of life lies in the challenging of the past, which is symbolized by the foot of the snow mountain when it comes to the picture offered above.
in reality, some people are inclined to be content with their present life and they are willing to pass their life in a steady lifestyle. some others, however, are constantly aggressive, almost restless in pursuing their aims. it is hard to say the former way is dull but it is really the latter that will make our life as colorful and beautiful as the magnificent scenery. put it the other way around, when the sightseer is standing on the top of a mountain, his sense of victory is beyond any limited description.
