Mount Qomolangma
Many climbers dream of reaching the world’s highest top- Mount Qomolangma. But there is heavy snow and the oxygen (氧气) level is very thin. So Mount Qomolangma seems to say no to any climbers. Tenzing and Edmund were the earliest to arrive at the top, but they were up there for just 15 minutes before coming down.
