縛眾洞中 The Captives Hung in the Cave
那老魔聞言，滿心歡喜道：「造化，造化。拿住這廝，唐僧才是我們口裡的食哩。」叫小妖：「快安排酒來，且與你二大王奉一個得功的杯兒。」二魔道：「哥哥，且不要吃酒，叫小的們把豬八戒撈上水來吊起。」遂把八戒吊在東廊，沙僧吊在西邊，唐僧吊在中間，白馬送在槽上，行李收將進去。那老魔闻言，满心欢喜道：「造化，造化。拿住这厮，唐僧才是我们口里的食哩。」叫小妖：「快安排酒来，且与你二大王奉一个得功的杯儿。」二魔道：「哥哥，且不要吃酒，叫小的们把猪八戒捞上水来吊起。」遂把八戒吊在东廊，沙僧吊在西边，唐僧吊在中间，白马送在槽上，行李收将进去。
逐句解 Line by line
The old fiend, hearing this, was filled with delight: “What luck, what luck!
滿心歡喜 (mǎn xīn huān xǐ), “heart brimming with joy.” 造化 (zào huà), “good fortune, a stroke of luck” — the elder's fear gives way to glee.
“With this fellow caught, Tripitaka is at last the meat in our mouths.”
這廝 (zhè sī), “this fellow” — Pilgrim. 口裡的食 (kǒu lǐ de shí), “food already in the mouth,” i.e. a sure thing; the final 哩 (li).
He called to the little imps: “Quick, set out wine — let's offer your Second King a cup for his success.”
小妖 (xiǎo yāo), “the little imps, minor demons.” 得功的杯兒 (dé gōng de bēi er), “a cup [in honor] of the exploit,” 得功, “to win merit”; 杯兒 takes the suffix 兒 (er).
The second fiend said: “Brother, hold off on the wine — first have the lads fish Zhu Eight-Rules up out of the water and string him up.”
撈上水來 (lāo shàng shuǐ lái), “to fish up out of the water” — Eight-Rules had gone off to bathe in the pool earlier in the chapter. 吊起 (diào qǐ), “to hang up, string up.”
So they hung Eight-Rules in the eastern gallery, Sha Monk on the western side, and Tripitaka in the middle; the white horse was put to the trough, and the baggage stowed away within.
東廊 (dōng láng), “the eastern gallery, covered walk.” 槽 (cáo), “a manger, trough.” 收將進去 (shōu jiāng jìn qù), “gathered and stowed away,” 將 a particle of motion.
The elder fiend's dread turns to glee: with Pilgrim pinned, Tripitaka is “the meat in our mouths,” a sure meal at last, and he calls for wine to toast his brother's success. The younger, more careful in victory than the reader might expect, checks the celebration — first secure the whole party, beginning with the forgotten Eight-Rules, who must be fished from the bathing-pool where the chapter's opening left him.
The passage ends by disposing the captives with an almost housekeeping precision — Eight-Rules to the east, Sha Monk to the west, Tripitaka in the middle, the horse to the trough, the baggage stowed. The tidy arrangement measures how total the demons' victory now seems. Yet the chapter has been careful to leave one thread loose: the Great Sage lies pinned, not slain, beneath his three mountains — and it is from that single unclosed possibility that the rescue will come.
