An alpine climbing activity that relies on a large number of hired personnel. Since the 1920s, the international mountaineering movement has been developing and climbing heights have been rising. The weight and transportation of equipment and food have grown rapidly. It is difficult for the climbers themselves to complete the task of transporting all the necessary materials in the mountaineering process. Therefore, a large number of local mountain residents are required to serve the team. The ratio of the number of climbers to the number of hired personnel is generally one to three, that is, one climber is equipped with three auxiliary personnel to form a pyramid-shaped stratification station, and a station is set aside as a "station type" transport and support line. This type of mountaineering activity has gradually lost its original significance. Since the middle of the 1970s, the International Mountaineering Organization has strongly advocated alpine climbing activities to restore the significance and role of sport in mountaineering.
