Rural areas are the product of the development of productivity to a certain stage. Generally, rural areas are geographical areas located outside of cities and towns. Studies have pointed out that there has been an education crisis that affects the country's development, and the rural population is the biggest victim of this crisis. The main reason is that cities have a significant advantage in allocating scarce educational resources; simultaneously, school education in rural areas is highly inconsistent with people's learning needs. "Education for All" is a concept proposed by UNESCO at the World Education for All Conference in 1990 for the world. Its ultimate goal is to meet the basic learning needs of all children, youth, and adults. It is true that under the promotion of education for all, rural education in various countries of the world has developed to a certain extent, but compared with developed regions or urban areas, the quality of rural education is still worrying. This commentary discusses how teacher training and reforming rural education curricula have become fundamental approaches to rural education reforms in various countries.
