To a certain extent, it has curbed the phenomenon of returning to poverty due to illness and causing poverty due to illness, promoted the development of rural health services, promoted the change of farmers' concept of seeking medical treatment, and also enhanced the image of the Party and the government for private affairs. However, many farmers still do not know enough about this policy.
