Half of his life he is a father and his whole life is his family. Li Shoutian's life is the epitome of thousands of fathers: born in a famine year, raised in bitter cold, working from a young age to middle age, saving gifts for his children, building a new house, raising children for his grandchildren, worrying about his heart, swallowing the bitterness in his stomach, and carrying the burden on his shoulders. After a lifetime of hard work, there is no leisure for a moment, and the words "I will not be a human in the next life" when he is dying express the sadness and despair of the life of the little man at the bottom.
