Most people who make it to Mount Everest have experienced free solo climbing, as climbing inevitably involves scaling mountains and ridges.
There's a fundamental difference between climbing an 8000-meter peak and a scenic mountain area. In scenic areas, paths are constructed by investors; they may be steep or difficult, but they are incomparable to an 8000-meter peak, where every path is forged by the climbers themselves.
This is a human feat of conquering nature, often requiring the crossing of cliffs tens of meters high. Experienced climbers ascend, fix ropes hand-over-hand, and then others follow these ropes up. Sometimes ropes are strung between two cliffs with boards secured to them, and climbers traverse these boards without any additional protective measures—fall, and it's certain death.
Among those present, there are many elite free solo climbers, such as Lei Ming, the CEO of a major corporation.
