8,848.86 metres
To most people, Mount Qomolangma is one of the greatest wonders of the world. On the highest place on earth, you will feel like you are able to touch the sky. But only the best climbers reach the top, and that is only if they survive the terrible conditions first. On the mountain, temperatures can fall to -30 degrees. Climbers must also deal with thin air, high cliffs, and changeable weather.
Reaching New Heights
Before 1960, no one was able to reach the top of Qomolangma from the northern side. Mountain climbers even called that way the "Death Road", but a Chinese climbing team was determined to make the climb.
On 24 May 1960, climbers Liu Lianman, Wang Fuzhou, Qu Yinhua, and Gongbu arrived at the Second Step. It was 8,600 metres above sea level. People said it was so
Reaching New Heights
high that even birds could not reach it. Liu allowed his teammates to step on his shoulders. Bit by bit, the climbers pulled themselves up, and they made it past the Second Step. At 4:20 a.m. on 25 May, the Chinese national flag flew above the world's highest mountain for the first time.
Reaching New Heights
In 1975, another Chinese team climbed to the top of Qomolangma to do research. This time, they brought a ladder to the Second Step. Until 2007, almost all climbers from the northern side used this “Chinese Ladder” to reach the top much faster. In 2020, a Chinese research team went to Qomolangma to measure its height--8,848.86 metres.
Reaching New Heights
Climbing Qomolangma is dangerous. Some climbers reach the top successfully, but many fail. Why do people still risk their lives to climb the highest mountain in the world It is because human curiosity and ambition cannot be stopped. Or, as the English explorer George Mallory put it, it is simply "because it's there"!
