有何難哉 Where Is The Difficulty
八戒道:「不瞞你說,這三個妖魔,我師兄一棍就打死一個;我一鈀就築死一個。我還有個師弟,他一降妖杖又打死一個:三個都打死,我師父就過去了,有何難哉?」八戒道:「不瞒你说,这三个妖魔,我师兄一棍就打死一个;我一钯就筑死一个。我还有个师弟,他一降妖杖又打死一个:三个都打死,我师父就过去了,有何难哉?」
逐句解 Line by line
Bajie said, "I will not deceive you. Of these three demons, my elder brother will kill one with a single blow of his cudgel;
不瞞你說 is the same set opener his brother used before naming himself. The arithmetic that follows is the joke: three demons, three disciples, one each.
I will kill one with a single stroke of my rake.
一鈀 is the site the chapter's opening survey singled out: the rake's character is one this project raises everywhere, and the raising happens to leave the 一 in front of it untouched, because both readings sit in the same tone class. 築 is to tamp or ram, the verb for pounding earth — which is what a nine-toothed rake does to a head.
And I have another younger brother who will kill one with his demon-quelling staff. All three dead, my master goes through — where is the difficulty?"
降妖杖 is Sha Monk's weapon, and 降 is xiáng, to subdue, not the jiàng of coming down. 有何難哉 is deliberately literary — a classical flourish, the kind of thing a man says when he has just done some very simple sums.
Bajie's plan is arithmetic. Three demons, three armed disciples, one apiece, and the road is clear. Laid out like that it is unanswerable, which is exactly what is wrong with it.
The classical flourish at the end gives him away. Where is the difficulty is not how anybody talks on a hillside; it is how you talk when you are pleased with your own reasoning and want it to sound inevitable.
And the reader can already see the flaw, because the old man has not finished. Bajie has counted the chiefs and forgotten to ask about anybody else.
