Imperial edicts in ancient China were with strong political preference and practicality. It is very meaningful to interpret the psychological meaning of the emperors and necessary to analyze the sociality and individuality of emperors based on their imperial edicts. This paper analyzed the differences of psycholinguistic features in imperial edicts of Song and Ming dynasties via Classic Chinese LIWC (CC-LIWC) to obtain word frequency results for each word category in the edicts and used statistical tests to compare the differences of functional words-personal pronouns, emotional process words, cognitive insight words, physiological process words and motivational level words - in the edicts of Song and Ming dynasties. The result indicates the differences in CC-LIWC lexical frequencies between Ming and Song dynasties had an impact on the intensity of the emperors’work and their mentality in dealing with state issues.</p
