Han Song, a volunteer teacher from Beijing, was intimidated by the harsh and dangerous living environment when he first arrived in Tibet. He was chased by the wolf king and attacked by animals at night. The difficult living conditions overwhelmed him, but the enthusiasm and care of the Tibetan students and compatriots warmed people's hearts. The innocence in the children's eyes and their desire to learn infected Han Song. He overcame all difficulties, took on the teaching of all subjects, and forged a deep friendship with the children in their daily interactions. The peaceful and beautiful years of volunteer teaching were broken. Rampant poachers broke into the school at night and injured people. Han Song and the students experienced the test of life and death, and had to part because Han's mother, who was far away in Beijing, was critically ill. In the eager anticipation of all the students, Han Song finally chose to return to the plateau and dedicate his youth and life here. Together with the kind and beautiful Tibetan girl Gesang Meiduo, he helped generations of Tibetan students change their lives and realize their dreams.
