The socialist society is a very long historical stage. In socialist society, after the nationalization of industry and the collectivization of agriculture have been realized and the socialist transformation of the ownership of the means of production has been completed, class contradictions still exist, and class struggle has by no means died out. In this historical stage, it is necessary to carry out a thoroughgoing socialist revolution on the economic, political, and ideological and cultural fronts. At the same time, as long as imperialism, capitalism, the reactionaries of various countries, and modern revisionism exist in the world, the sinister wind of capitalism will from time to time blow into the socialist countries. Therefore, in the socialist countries, the struggle between socialism and capitalism over which will win out will require a very long time before it can be finally resolved.
