The Chinese Communists have been calling on people to engage in various struggles and not only in such general areas as thought and class. Struggle even exists on the personal level between parents and children, husband and wife.
共產黨號召人民搞思想鬥爭，路線鬥爭，生產鬥爭，還有階級鬥爭，人臉比狗臉變得還快，別說是朋友，就是父母與兒女之間，妻子與丈夫之間隨時都會因為階級立場問題翻臉的。
