Introduction:
Du Yuhui's soul traveled to a six-year-old child in the early years of the Southern Song Dynasty in an accident. He was a good fisherman, a doctor and a chess player. Due to his young age, he could only cooperate with his parents to express his ideas in the form of a double reed and put them into practice. During this era, he witnessed the economic prosperity of the Great Song Dynasty, but also faced military threats from neighboring powers. Du Yuhui hopes to improve this situation through his own efforts and bring more benefits to the country and its people.
