 the public de-monst-rations is an effecive way to express  one's opinion.Because if some people in China sufferred from unfair treating such as the swindle of the state-owned enterprises.He didn't have an effective way to retrieve the loss but suffering since the the state-owned enterprises are all protected by the government and that means it's useless  if you turned to courthouse for help.And the public de-monst-rations has provided an way to express many people suffered from the same thing.No way can supervise and urge the governmet-related unfair performaces but this may warn the them to be fair-minded.The similiar examples are too many,such as the facotories take up the farming land unjustifiable under the permits of the government.even with the help of the social evil forces.The officers of the local goverment is afraid of them and just pretend to overlook the force misdeed.And the cictims don't have any ways to preserve their life-like rights but gathering and de-monst-rating.So do many cases as the  unreasonable charges of the China Mobile,the unreaonable charges of  state-owned commercial banks.This kind of this case cannot be solved without the public de-monst-rations to urge the relative deparment to do something.Or the rights of the people will be violated  constantly.But in China this unfair case is happening all the time, just because the government don't allow the public de-monst-rations in  mainland. I finally understand  why the private  rights of  some developed are protected better than us,that's why they call the Chinese people have no private rights.
