The Political Atmosphere and the Complication of SANGUOZHI in the Early Stage of West Jin Dynasty

In the age of three kingdoms,all of these dynasties want to get legitimate status. On the one hand,the rulers of West Jin dynasty want to show their own legitimate status by affirming the legitimate status,because of the West Jin dynasty born out of Wei dynasty; on the other hand,when the West Jin dynasty completed national unification,the influence of Shu Han and Sun Wu dynasties has been weakened,but the Wei dynasty still have great influence at that time. Under such situation,the rulers of West Jin dynasty need a reasonable explanation about the substitution of West Jin dynasty for Wei dynasty.Chen Shou and his SANGUOZHI are influenced by this atmosphere. In order to explain its substitution rationality,SANGUOZHI is emphasized in praising the achievements of Wei dynasty,but debasing the rulers' moral and family origin in Wei dynasty.
