The Herdsman (1982)

In 1980, Xu Jingshan, a wealthy Chinese-American businessman returns to China to find his son, Xu Lingjun, whom he had abandoned over 30 years earlier. Labeled a rightist because of his capitalist father, Lingjun has been forced to live as a humble herdsman on the grasslands. His bitter life has been transformed by a happy marriage to the wise and beautiful Xiuzhi, and more recently by his rehabilitation by the Party. When he goes to Beijing for their reunion, he discovers his father wants him to work for his chemical company in San Francisco. Lingjun tells the story of his life to his father, as he ponders his future.
