The purpose of this study is to analyze the errors of the five cohesive devices in the Chinese writing texts of Koreans. The five cohesive devices are reference, substitution, ellipsis, conjunction and lexical cohesion. As a result of the error analysis, there were not many errors in substitution and lexical cohesion. However, there were many errors in reference, ellipsis and conjunction. Reference error was 14%, ellipsis error was 31%, conjunction error was 44%. Reference were many errors related to singular and plural of personal pronoun, and respective expression of the second personal pronouns. Ellipsis errors are caused by missing words that should appear in the subject or object position. Conjunction errors were most often caused by misuse of similar meaningful conjunction expressions.
