At 8,848.86 metres, it is the highest place on Earth. Climbing it is dangerous because of low temperatures, thin air, and changeable weather. Before 1960, no one had reached the top from the northern side. The path was so difficult that climbers called it the “Death Road”. But a Chinese team was determined to try. In May 1960, they finally reached the top. Liu Lianman even let his teammates step on his shoulders to climb over the Second Step. They flew the Chinese national flag on the top for the first time. Later, Chinese teams continued to climb. In 1975, they brought a ladder to the Second Step, which later became known as the “Chinese Ladder”. It helped many other climbers reach the top. In 2020, a Chinese research team measured the mountain’s height and confirmed it as 8,848.86 metres. People still risk their lives to climb Qomolangma. Why? Because human curiosity and ambition cannot be stopped. As explorer George Mallory said, “Because it’s there.” 11. Why is climbing Qomolangma dangerous? A.
