Generally, Mount Everest can be climbed from two directions, one is the southern slope of Nepal and the other is the northern slope of China. Compared with the south slope, the terrain of the north slope is more complicated, so it is very difficult to climb it, and it may not be possible to climb it. The weather must be fine. So many mountaineers in the world like to go to the south slope of Nepal first, and then try to climb from the north slope of China.
