Abstract: The language of South Korea's Chinese literature Yan Xing Lu is a kind of "mixed Chinese". There are many Korean
language components, and the inherent vocabulary made up of Korean Chinese characters is a very important category. Korean Chinese
characters can be divided into four types, namely characters that created by Korean people not Chinese people, Chinese characters for
recording the pronunciation of some Korean vocabularies, Chinese characters for recording the special meaning of some Korean
vocabularies, and Chinese characters from officials. It is helpful for interpreting this batch of oversea Chinese classics to dig these
inherent Chinese characters from Korean Chinese literature.

Key words: Yan Xing Lu, oversea Chinese classics, inherent Korean-Chinese characters
