Before climbing a mountain, we must first obtain relevant information to understand the altitude and difficulty of the target mountain range. Pay attention to safety and wear appropriate mountaineering clothes and equipment, such as rubber shoes, hiking poles, helmets and dog tags. Don't neglect safety issues because of saving money. To maintain respect for mountains, it is necessary to cut down fewer trees and pick up fewer stones to protect the tranquility and primitive state of mountains. Must have certain knowledge of accident handling and necessary skills for field survival. In case of danger, call for rescue in time and maintain good communication conditions.
