Why did Sun Simiao study medicine?

Sun Simiao's hometown is Jingzhao Garden (now Yaozhou, Shaanxi). Due to poverty and lack of food and clothing, Sun Simiao was in poor health when he was a child, and he was often ill and suffered a lot. He often sees many poor people get sick, or because they have no money to treat diseases, or because they can't be cured, they are killed by diseases at a young age. He was sad to see people crying, and an idea sprouted in his mind: "How important it is to save a life! Although gold is expensive, it can still be bought with money, and no amount of money can buy life. " In Sun Simiao's young mind, I set up a grand ambition: I want to study medicine seriously, be a good doctor, and relieve the suffering of thousands of people and their relatives in Qian Qian.
