Through the comparative study of education in various countries, we can learn the successful experience and failure lessons of foreign education, provide reference for our educational reform, and provide basis and reference for our educational decision-making and educational reform.

Thirdly, as an intermediary cultural form of "comparative culture", comparative education plays a major role in the exchange and cooperation of educational theories among different nationalities and countries. The communication between these different cultures is one of the important driving forces for the innovation and progress of educational science. The study of comparative pedagogy has reached a worldwide scale. We can also carry out research in this field to enhance international understanding and promote international cultural exchanges.
