When you say hump, you should mean the famous hump route, which was a major air passage between China and its allies during World War II. It started at 1942 and ended in World War II. There are many historical stories. The "Hump Route" starts from Assam in the west, goes to Himalayan Mountain, Gaoligong Mountain, Hengduan Mountain, salween, Nujiang River, Lancang River and Jinsha River in the east, and enters Yunnan Plateau in China and Sichuan Province. The total length of the route is 500 miles, the terrain is 4500-5500 meters above sea level, and the highest altitude is 7000 meters. The peaks rise and fall like camels' backs, hence the name "Hump Route".

From Kunming to Tengchong by plane, you have to go through the hump route. Now many bars are named after "hump".
