You should pay attention to state affairs and carry the Great Proletarian Cultural Revolution through to the end! - Mao Zedong

国际主义者的共产党员，是否可以同时又是一个爱国主义者呢？我们认为不但是可以的，而且是应该的。

All contradictory things are interconnected; not only do they coexist in a single entity in given conditions, but in other given conditions, they also transform themselves into each other. This is the full meaning of the identity of opposites. This is what Lenin meant when he discussed "how they happen to be (how they become) identical--under what conditions they are identical, transforming themselves into one another".

我们三年来从斗争中所得的战术，真是和古今中外的战术都不同。用我们的战术，群众斗争的发动是一天比一天扩大的，任何强大的敌人是奈何我们不得的。我们的战术就是游击的战术。大要说来是：‘分兵以发动群众，集中以应付敌人。’‘敌进我退，敌驻我扰，敌疲我打，敌退我追。’‘固定区域的割据，用波浪式的推进政策。强敌跟追，用盘旋式的打圈子政策。’‘很短的时间，很好的方法，发动很大的群众。’这种战术正如打网，要随时打开，又要随时收拢。打开以争取群众，收拢以应付敌人。三年以来，都是用的这种战术。
