在北大演讲,开场我就说:“这本身就是个笑话,没上过学的人给认字的人讲道理,肯定得胡说!忙的同学赶紧忙去,别在这儿瞎耽误工夫,实在没事回去睡觉都比这强。我将要说的这些废话你爹妈都说过很多遍了,想听的孩子早就记住了,不想听的孩子再听也是这耳朵进去那耳朵出来。” In Peking University speech, the opening I said: "This is a joke in itself, did not go to school people to justify people who recognize, certainly nonsense! Busy classmates hurriedly go, do not blind delay here, in fact, Nothing to go back to sleep than this strong.I will talk about these nonsense your father and mother have said many times, want to hear the child has long been remembered, do not want to listen to the child is listening to this ear into that ear out.
