- 15. Several English words for explanation I'm watching Kung Fu Panda with English subtitles. As a result, Shifu's father can't find many words Shifu's father was robbed. After being rescued, he said: "despite their malitudinous intentions, those ruffians hard me not one jot or one title." What is that "malitudinous"? Second: "it would see we thought that hooligans a badly needed lesson in interpersonal affiliators." What is the "affiliators" in it? The third one is "I assure you, my motives were absolutely optimistic." What's "aprivastrian"? It seems that the old man said some strange words, because after he said "inter personal affiliators", Po hesitated for a while, then pretended to understand and praised the old man's skill Fourth: "Shifu, I can't possibly express the full dressipersity of my..." "Is that a good thing, right?" he asked The fifth: "well Shifu it's like your old man said: 'you are otherwise predictable.'" I don't think Po wants to learn the old man's style of speaking - to say strange words. Because Shifu then agreed: "Po. I guess I am." from here we can see that Shifu doesn't understand what it means That old man is a charlatan, I think he said these strange words are not necessary to demagogue people, does that mean that the translation of these words is not meaningful?
