In the 21st century, new trends in the study of international humanities and social sciences are gradually being formed. These new trends are mainly due to the "globalization" of the times and the "leap in Asia", which are being created through the interaction of these two capabilities. Asia's leap is not only the great spiritual traditions and religious beliefs such as Confucianism, Buddhism, Taoism, and Shinto that appeared in the past history of Asia, It also affects culture. We will review the dissemination of Chinese characters and Chinese texts through reconstruction of East Asian Chinese culture, and examine the influence of Chinese culture in the political, economic and cultural areas of Chinese characters. Particularly, through concrete examples of the use of Chinese characters in Southeast Asian culture, we will seek to expand the culture of Chinese characters and look for ways to go along with them. We will make concrete plans and implement them step by step.
