Doubtlessly, the emergence of modern feminism opened the precedent in the theory of women＇s liberation in China and exerted a profound and far-reaching influence on women＇s liberation afterwards. But we must face up to the fact that there was some traps or misunderstanding of modern feminism, which were unfavorable for realizing women＇s rights and such influence was long, so much so that till today we are still seeing its existence. It is, therefore, necessary to have a full reflection of modem feminism, unveil the original meaning of women＇s rights and make women＇s rights return to human rights in order to make the development of women＇s fights continue.展开更多
