計議招贅 The Disciples Scheme
悟淨道：「二哥，你在他家做個女婿罷。」八戒道：「兄弟，不要栽人，從長計較。」行者道：「計較甚的？你要肯，便就教師父與那婦人做個親家，你就做個倒踏門的女婿。他家這等有財有寶，一定倒陪妝奩，整治個會親的筵席，我們也落些受用，你在此間還俗，卻不是兩全其美？」八戒道：「話便也是這等說，卻只是我脫俗又還俗，停妻再娶妻了。」悟净道：「二哥，你在他家做个女婿罢。」八戒道：「兄弟，不要栽人，从长计较。」行者道：「计较甚的？你要肯，便就教师父与那妇人做个亲家，你就做个倒踏门的女婿。他家这等有财有宝，一定倒陪妆奁，整治个会亲的筵席，我们也落些受用，你在此间还俗，却不是两全其美？」八戒道：「话便也是这等说，却只是我脱俗又还俗，停妻再娶妻了。」
逐句解 Line by line
Wujing said, “Second brother — you be the son-in-law in her house.”
悟淨 is Wujing (Sha Monk); 二哥 “second elder brother,” his address to Bajie. 女婿 “son-in-law.” The disciples' private scheming to marry Bajie off now begins.
Bajie said, “Brother, don't go foisting it on me — let's weigh it at leisure.”
栽人 “to frame, to pin (a thing) on another.” 從長計較 — 從長 “at length, unhurriedly,” 長 here cháng (not the zhǎng of 家長 “household head”). Bajie stalls rather than refuse — the tell of a wavering resolve.
Pilgrim said, “Weigh what?”
行者 xíng zhě. 計較甚的 “reckon what?” — 甚 here shén (= 什, “what”), interrogative.
“If you're willing, we'll just have the Master and the woman become in-laws, and you become a married-in son-in-law.”
親家 “relatives by marriage, in-laws.” 倒踏門的女婿 “a son-in-law who marries into (and lives at) the wife's house,” the uxorilocal arrangement the widow proposed; 教 the causative jiào.
“A house so rich in wealth and treasure will surely furnish a dowry besides, and lay on a wedding-feast; we too would come in for some good cheer, and you would return to lay life here — would that not be a thing perfect on both sides?”
倒陪妝奩 “to provide a dowry in return,” 妝奩 the bride's trousseau. 會親筵席 “the wedding-relations' banquet.” 還俗 reads huán sú, “to return to secular life,” 還 the verb “return.” 兩全其美 “perfect for both parties.”
Bajie said, “That's all very well to say — only, having left the world and then returned to it, I'd be keeping one wife and taking another.”
脫俗又還俗 “to quit the world and re-enter it,” 還 again huán. 停妻再娶妻 “to keep a (first) wife while marrying a second,” i.e. bigamy — Bajie's slip that reveals he already has a wife, the opening for Wukong's exposé.
With the public confrontation over and the household shut against them, the scene turns to the disciples' own scheming — and the target is Bajie. Wujing floats the idea, Wukong seizes on it, and between them they sketch a whole comic arrangement: Tripitaka and the widow as in-laws, Bajie as a married-in son-in-law, a dowry, a wedding-feast, and “some good cheer” for the rest of them into the bargain.
The mischief is characteristic of Wukong, who has read Bajie's appetite exactly and now dangles it before him under cover of brotherly helpfulness. The proposal is only half a joke: it offers Bajie precisely the thing his fretting has shown he wants, while letting the others watch to see whether he will take the bait.
And Bajie half-takes it. His objection is not that the marriage would betray his vows but that it would be bigamy — “keeping one wife and taking another” — an admission, blurted almost in spite of himself, that he still has a wife back home. The slip hands Wukong his cue, and the passage ends poised for the exposure of Bajie's past that follows.
