To what extent did Chinese characters affect Korean and Japanese?

The research question is that to what extent did Chinese characters affect Korean and Japanese. The specific aspects that will be discussed are the history of Chinese characters, Korean alphabet and Japanese writing system, the connections between Chinese, Korean, and Japanese languages, and the influences on the cultures and developments.There are some significant reasons to do such a project. Learning about the relationships among East Asian languages would make it easier to understand the special links between Asian countries and, therefore, find solutions for cultural conflicts. Also, it is related to my personal interests.The methodologies mainly used in this project were to search for previous papers and collect data from some official databases. This project is greatly related to historical aspects, so the research done by others was essential. Some data from reliable data sources were also required to list some figures to support my idea.From this project, it is shown that there were very close relationships among East Asian countries in both linguistic and cultural aspects. Chinese characters were the root of the languages in China, Korea, and Japan. Therefore, it is important to know about Chinese characters when learning Chinese, Korean, or Japanese.
