The pass in the geographical sense refers to the obvious saddle-shaped depression on the ridge. The local people don't climb mountains for the sake of climbing them. They just want to cross the pass and get in and out of the mountains in the shortest and most labor-saving way. The wind at the mountain pass will be particularly strong. The saddle at the lower elevation of the ridge, that is, the lower part between two connected peaks, is called the pass. Yakou is a common word on the Sichuan-Tibet line, which is often a traffic tunnel in the mountains.
