Abstract: In the middle and late Western Jin Dynasty,it was difficult for the sons and the younger brothers of poor families to get a fair chance for promotion.The court of Western Jin Dynasty took some measures to try to break the current situation of “selecting officials according to family status”.It met the expectations of many people of insight to promote people who were humble origin with talents.The famous metaphysicians promoted some friends with humble origin and let them enter the bureaucracy in the late Western Jin Dynasty.These people with humble origin had no political talent.The famous metaphysicians did not realize the contemporaries' expectation of “sorting out the order of talents”.They took the official position of the state as their exclusive domain and used public power to provide convenience for themselves and their friends.The famous metaphysical scholars in the Eastern Jin Dynasty no longer promoted people with humble origin.They formed a closed community of interests and monopolized the important positions in bureaucratic system.

Key words: Western Jin Dynasty, famous metaphysician, people with humble origin, social intercourse
