                            In the past, China  was known as "the sick man of Asia", because people’s lives depended on god. There  was no public health system or scientific treatment. The health education aimed  at creating rural medical system, building clinic and hospital and training  doctors. In 1934, the medical system was implemented in the county and each  farmer only needed to pay 0.1 yuan per year. Yan made great contribution in  controlling smallpox and curing trachoma.                              |
