The anti-government movement which was led by People’s Alliance for Democracy （PAD） of Thailand，turned from “non-violence” to “violence” at last，because the “anti-Thaksin” camp could not contain “Thaksin-Thai Rak Thai party” group from staging to a comeback by using conventional means，could not prevent the People’s Power Party （PPP） from amending constitution in order to rebuilt the one-party dictatorship system，and could not withstand the “public opinion of ballot” of “pro-Thaksin” camp anymore. According the paper，although “Thaksin-Thai Rak Thai party” group was defeated by the “anti-Thaksin” camp again，and lost the ruling status，if the political interests of new industry class and peasant class can not be guaranteed，“Thaksin-Thai Rak Thai party” group will surely comeback and may lead to another turbulence. Multi-party system，rural-urban disparity and economic crisis，make the future of political situation of Thailand full of uncertainties.
