The Tibetan Dog

Jiantan is a young boy who has to leave Xi'an after the death of his mother to go deep into the Tibetan prairies and start living with the father he barely remembers. His dad, LaGeBa, is a busy doctor who decided to depart from the city and reside in Tibet where he is the essential physician of the poor community he lives in. To help his father, Jiantan has to learn how to herd sheep. While trying to learn his new responsibility, he is saved by a stray gold-colored Tibetan Mastiff. Both Jiantan and the big dog help each other as they try to adjust to this new environment.
