They are classmates, the same age, Yamaliva in a poor area, life in the fifties, friends for half a century. Only because of the reform of the college entrance examination system in 1977, the lives of the two people have been clearly separated. Fifty years have passed, and one is a hardworking fruit farmer in a closed small mountain village, working at sunrise and resting at sunset, and years and years, young men become old farmers. One is a small cadre who has worked hard for 40 years in an institution, busy and diligent. There is no big money, a well-off is safe, and now he is a member of the retired army. Life experiences are different, but friendship is always innocent.
