Mr. He is almost 70 years old. He is from Zhubu Village, Ninghai, and his skill to catch snakes is inherited from past generations. Besides planting, he often goes into mountains to catch snakes at night. Zhubu village is located in the remote mountain area, and many villagers have the skill to catch snakes because it is a great part time job for them. However, selling the snakes is not easy. Mr. He has had the snake for half a month for now, but he is still unable to make a good amount of money. His nephew lives with him and his wife. When the nephew was 7 years old, his mother got cancer, while his father got cerebral hemorrhage. The responsibility of caring for him comes to this old couple.
