Well-known as the highest peak in the World, the history of Mount Everest is more like a story book of brave and indomitable people. Some lost their lives on the road to the top, while some left their footprints on the peak. Since the first have successfully climbed Mount Everest.
There is a sentence saying “it is the worst time, it is the best time”. For adventurers who are now standing on the top of the Mount Everest, they may know the actual meaning of the sentence. The extreme cold, hurricane-force winds, and low oxygen levels (about one-third of the oxygen in the atmosphere as at sea level), the potential dangers which may cause people to lose life immediately, all of these frightens and threats finally turn into the extremely joy when they get to the closest point to the sky.
