Salesman Liu Wen traveled to Tibet because of unemployment and family problems, and met Li Lelong, who had been in Lhasa for some time. The two gradually became familiar with each other, traveled to various places together, took care of each other, formed a deep friendship, and each solved their own inner problems. Liu Wen left Tibet first, but Li Lelong had nothing to do and had to stay in Lhasa for a while.
