After the collapse of the Eastern Han dynasty, the early medieval Chinese aristocratic society comprised of scholar-officials was gradually built up on the basis of the Nine-Rank system. During the Six Dynasties, the Ministry of Personnel and the local Rectifier (zhongzheng 中正) were in charge of civil appointments and merit ratings, and with the rapid growth of the aristocratic society, personnel files and civil documents used in the selection process of officials were transformed in format and in content. The most notable of all were positive descriptions of officials and their families (buzhuang 簿狀) derived from detailed conduct descriptions (tiaoshu xingzhuang 條疏行狀), which had been mainly about personal ability and conduct in office in the Han dynasties, but now primarily concerned a family’s records of marriage and official ranks. These documents played a crucial role in the medieval Chinese bureaucracy, and although in later times their format and meaning were completely changed, we can discover in them a transformation of early medieval China.
