The bus drove from Shangri-La to Deqin, and stayed in the middle for3-4 times, including the Baima Snow Mountain Exit (4292 meters above sea level), without passing the Jinsha River Dawan. This road is actually not long, but it is all Panshan Road, which is particularly difficult to drive. If you drive by yourself, you need technology and physical strength. There is a tunnel in the middle that is still under repair, and it is expected to be completed at the end of the year. After completion, the driving time from Shangri-La to Deqin will be shortened from 4 hours to 3 hours, and the driving difficulty will be greatly reduced.
