The five-year-old Wang family in Qingshui Village is a sick man. The whole family is a strong man who can carry a cauldron, but he is frail and sick. He fell into a coma after being sent by his father to pick up pig blood. When he woke up, he merged his memories and faced the contrast between his family members - the eldest brother carried the pig as fast as he could, the younger sister bouldered and smashed apricot kernels, and the father easily lifted a 500-pound millstone. His mother felt sorry for him and suggested that he send him to study to find a way out. However, the family was financially poor, his father was worried, and his sister-in-law was even more critical. This trip to study became the only chance of survival for the frail Wang Sanniu in the Hercules family.
