Why are high mountains and extremely high mountains popular places for mountaineering and scientific research?

Because only high mountains and extremely high mountains can show the ability of climbers.

As for why humans climb, it is because they want to challenge the limits and represent an honor. The northern slope of Mount Everest is more than 8000 meters above sea level, and the climate is harsh, accompanied by strong winds and low temperatures. It is an insurmountable mountain recognized by the global mountaineering community. Before 1960, the British mountaineering team also lost halberds on the north slope of Mount Everest three times, claiming that it was an unattainable route and even birds could not fly to the summit.

On May 25th, 1960, the China mountaineering team reached the summit of Mount Everest for the first time. In the process of climbing, the China mountaineering team filmed every climbing stage, but the video data of the summit was missing, which proved that only Comrade Qu of the China mountaineering team photographed a set of footprints of the summit when he went down the mountain. Many western media used the excuse of insufficient evidence and refused to acknowledge the fact that the China mountaineering team reached the summit of Mount Everest. Based on this background, the climbers created a tough guy like Qu, saying that if I were given another chance, I would die to keep the camera, which touched thousands of viewers.
