(論國民黨) 有很多的頑固分子，他們是頑固專門學校畢業的。他們今天頑固，明天頑固，後天還是頑固。什麼叫頑固？固者硬也，頑者，今天、明天、後天都不進步之謂也。這樣的人，就叫做頑固分子。要使這樣的頑固分子聽我們的話，不是一件容易的事情。 - Mao Zedong

Without preparedness superiority is not real superiority and there can be no initiative either. Having grasped this point, a force which is inferior but prepared can often defeat a superior enemy by surprise attack. We say an enemy on the move is easy to attack precisely because he is then off guard, that is, unprepared.

优势而无准备，不是真正的优势，也没有主动。懂得这一点，劣势而有准备之军，常可对敌举行不意的攻势，把优势者打败。我们说运动之敌好打，就是因为敌在不意即无准备中。

Now there are two different attitudes towards learning from others. One is the dogmatic attitude of transplanting everything, whether or not it is suited to our conditions. This is no good. The other attitude is to use our heads and learn those things that suit our conditions, that is, to absorb whatever experience is useful to us. That is the attitude we should adopt.
