These are the characters that are not used in Mandarin and Korean, the characters that are used in Korean but not in Mandarin, the characters that are used in Mandarin but not in Korean, and the characters that are used in Mandarin and Korean. In this paper, only the first and second cases of these four cases are examined. These two cases have similarities, that is, they are influenced by ancient Chinese. The first case, of course, is not only influenced by ancient Chinese, but also was newly created in Canton dialect. However, this text only deal with the parts that affected by ancient Chinese.
