The Operation Car Wash in Brazil，which lasted for four years，has dealt a heavy blow to the organized crime and corruption system and the interests of the traditional elite，bringing an overall impact on the current administrative，legislative and judicial system. This article will conduct a comprehensive review of Brazil's anti-corruption operation centered on the Operation Car Wash，pointing out the new features and analyzing the reasons behind，and then explore the its impact on the current state and future trend of Brazilian political arena. It is foreseeable that with the approach of the 2018 presidential election，the uncertainty of political situation in Brazil will continue to increase. On the one hand，under the dual effects of the economic crisis and the anti-corruption campaign，the traditional political parties suffer from a poor reputation and the presidential candidacy remains uncertain due to the Operation Car Wash；on the other hand，the Third Way is growing，seeking a middle ground between the left and the right wing. And this has also brought new opportunities for a strategic layout in the last year of Michel Temer's governance in order to defend his politics heritage.
