In order to avoid the ill infection, the thesis put forward the countermeasures: changing the government's function, improving the mechanism of evaluation about Levy upon ground and housebreaking, the property exchange should exchange the original address'property. The problem of farmer who loses ground is a serious factor that produces inharmonic society. In order to avoid the ill infection, the thesis put forward the countermeasures: the farmer should be guaranteed by the lowest life guarantees, establishment and perfect the system of farmer's endowment insurance and medicare, establishment and perfect the education and the training mechanisms of farmers who have no ground. The problem of housing that the people who have no money or a little money is the other factor that produces inharmonic society. The thesis put forward the principle of the countermeasures: one is there is house for the people who no money or have a little money for house to live; one is that the countermeasures dont affect the marketization of the housing reform. According to the principle,the thesis put forward the approach:improving on the economical-housing policy,extending low-cost house policy,the rental allowance should mainly for money.
