Abstract: There  are  three events which occurred in relation  to the suppression  of corruption  during the Kangxi  reign.The  earliest  stage emphasized  instruction  and issuing  of imperial decrees;The  middle stage reinforced  this propaganda   and punished severely a   number  of corrupt officials.At   the same time,the propaganda advocated being free from corruption  and  promoted  and protected  upright  officials；In  the  last  stage，there was more kniency  in  dealing  with corruption and reprimanding the  defects of  upright officials。This paper examines the three periods,describing  their different effects,and  demonstrating that Kangxi’s  tolerance toward corruption  in  later  period accelerated  officials’ degeneration.The author  concludes that Kangxi  had his  own  limitations ,but his insistence  on  suppressing corruption  and advocating uprightness  was  praise worthy.
