Abstract: East Asia is a geopolitical and cultural concept.East Asian Yi-ology originated in China.After the spread of other countries,it continued to show the synchronization and continuity of its development,the similarity of its ideological methods and the diversification of its localization process.The study of East Asian Yi-ology takes East Asian Yi-ology as the research object,reflecting on the achievements of Yi-ology in East Asian countries as a whole,exploring the internal logical relationship of East Asian Yi-ology,the consistency of interpretation methods and ideas,the localization process,and the development trend of East Asian Yi-ology.East Asian Yi-ology is characterized by the coexistence of inheritance and development,integration and diversification.The study of East Asian Yi-ology is different from the Yi-ology study of East Asians.The study of East Asian Yi-ology should jump out of the narrow national consciousness and treat the Yi-ology of East Asian countries objectively and rationally with a more open and broad horizon.Nowadays,with the interactions and exchanges of international academic in East Asian Yi-ology,the personalized and localized Yi-ology research is becoming less and less obvious.A new pattern of cross-study of Yi-ology in East Asian countries has been formed,and the integration of East Asian Yi-ology has become increasingly prominent.At present,the basic research of East Asian Yi-ology is not perfect,and the macro research of East Asian Yi-ology has not been paid attention to.The study of East Asian Yi-ology with new methods is on the rise.Therefore,it is the focus and new direction of the study of East Asian Yi-ology to continue to promote the basic research,the macro study and rhe new methods of East Asian Yi-ology.
