The bamboo-slips, unearthed at Kuo-tien, belong to Confucian literature in nature. The chapters on “Hsing-tzu-ming-ch'u” and “Wu-hsing” foucs on the cultivation of the mind and nature. The chapter, “Yu-ts'ung,” consists of some radom comments. The remaining slips deal obviously with rulership, which places its emphasis on “honoring virtues and righteousness” as well as “clarifying human relationships” as the two essential tasks of a king. The emphasis is placed on the prionty of blood relations. Thus, the relationship between brothers comes before that between the husband and wife, so is the case of the father and the king. Thus, filial piety is considered prior to one's loyalty to the king.
