Here is the Dele Mountain Pass at 4517 meters above sea level. The bus is driving on the winding mountain road. Everyone is attracted by the beautiful scenery outside the window. It has repeatedly requested that the flat road section can stop and enjoy the snow. Everything is so unreal, as if I have gone to outer space. I remember that there was originally a Dyer Lake here, because of the snow, so there was only a piece of whiteness between the heavens and the earth. After passing through this pass, I soon arrived at Seda, which is everyones biography. The holy city in the heart of Buddhism.
