Are there any movies about hump routes?

No movie directly describes the hump route, but indirectly describes it.

James Shelton, a British writer, wrote a famous novel The Lost Horizon. In the novel, an American pilot was forced to land on the grassland at the foot of a snowy mountain because of bad weather when flying over the hump route. This place is picturesque, simple and simple, and the locals call it Shangri-La. Later, the plane was repaired, and the pilot left this beautiful place and never came again. After the novel was made into a movie, Shangri-La became the meaning of "Xanadu", and even some hotel groups named it Shangri-La in order to get a quiet accommodation environment. In fact, Shangri-La is a Tibetan language, which means "the sun and moon in my heart", and it is the most beautiful realm of life in the eyes of Tibetans. If we want to interpret Shangri-La in the most accurate Chinese, it may be "perfection".
