赤膽少年心. It's the theme song of a show of Tibetan hot boys. The full name of the show is 藏风美少年. These young men are really talented. They wrote some of the songs themselves. The Tibetan name of the show seems to be བོད་ཀྱི་ན་གཞོན། ལེ་ཚན་དང་པོ།. Forgive me if I am wrong, as I don't read this language.
