This study analyzed the discussion points derived from previous research on the Chinese language curriculum and looked for the cause and reason. As a result of this study, the results show differences between researchers. The reason is that the timing of promulgation(notification) and implementation of the General Guideline of the National Curriculum and the Subject based Curriculum are different, the referenced materials have different standards, and there are errors in the information provided by the National Curriculum Information Center. When conducting research on the change of the Chinese language curriculum in the future, it is necessary to carefully consider various variables to select data, and the National Curriculum Information Center must re-examine its materials to ensure it can provide accurate information.
