Abstract: The 18th century saw the later period of the feudal society of China when the natural economy was still dominant the society。The development of the commodity economy was hindered by the Qing government policy which valued farming above commerce。An advanced class that could contend with the power of the feudal government had never been formed at that time.Without the leadership of an advanced class，peasants could only rebel the government spontaneously through the secret society，an under-developed organization in a primitive structure.They had no clear guiding principles of anti-feudalism.The movements under the appeal of “Against Qing whilst restore Ming” were all doomed to fail.Being righteous and progressive， those movements had inflicted heavy blows on the Qing dynasty.However ,since the basis of the feudal economy was still considerably stable,the peasants’s struggle could not push the Chinese history into a higher stage.
