『shangshu』, 『shijing』 are the oldest historical documents in China. Over a long period of time, language habits and using word habits have been mixed. So there are a lot of difficulties to interpret. In this article, I tried to analyze ‘毖’ among these characters. 『shangshu』 and 『shijing』`s ‘毖’ is mainly interpreted as ‘inform’, ‘cautious’, and ‘stabilize’. The excavated documents are not composed of ‘比’ and ‘必’. However, the Chinese characters related to ‘毖’ have continued to exist since the beginning of the oracle. Among them, ‘□’ expresses the meaning of stabilizing neighboring countries through military action, and it derives meaning such as ‘scold’, ‘Stable’, ‘Cautious’. Among these meanings, ‘密’ is related to ‘prudence’. One step further from here, ‘䛑’ and ‘怭’ were used as stylistic terms that the servant told the monarch. On the other hand, ‘毖’ has a close relationship with ‘愼’ and ‘誥’. ‘愼’ expresses the same meaning as ‘毖’ and has the same grammatical function. So we do not write together in the same literature. ‘誥’ expresses ‘inform’, ‘teach’, but there is a difference in usage. So these two Chinese characters were used together in the same document. In this paper, although only ‘毖’ is used as an analysis target, it is expected that the literature can be interpreted a little more accurately by considering the limited Chinese characters used in 『shangshu』 and 『shijing』 such as ‘毖’.
