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.
Reaching New Heights
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 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”!

1. How do you think the Chinese climbers felt when they placed the national flag on top of Qomolangma?
I think the Chinese climbers felt extremely proud and excited. They were the first to reach the top from the northern side after overcoming terrible conditions. Placing the national flag there meant they achieved a great goal for their country, so they must have also felt a strong sense of honour and satisfaction.
Discuss the questions.

2. What do you think George Mallory meant by “because it’s there”?
I think he meant that the mountain itself is the reason to climb it. It’s not for fame or money. It’s about human curiosity and the natural desire to challenge something that’s right in front of them—something big, difficult, and real.
3. What qualities do you think a good mountain climber needs to have?
a healthy and strong body
determined and never give up
good teamwork spirit
always stay calm
smart and brave
respect for nature
