殿上尋童 No Trace in the Hall
行至殿上，香火全無，人蹤俱寂，那裡有明月、清風。眾仙道：「他兩個想是因我們不在，拐了東西走了。」大仙道：「豈有此理！修仙的人，敢有這般壞心的事？想是昨晚忘卻關門，就去睡了，今早還未醒哩。」行至殿上，香火全无，人踪俱寂，那里有明月、清风。众仙道：「他两个想是因我们不在，拐了东西走了。」大仙道：「岂有此理！修仙的人，敢有这般坏心的事？想是昨晚忘却关门，就去睡了，今早还未醒哩。」
逐句解 Line by line
But when he came to the hall, the incense-fires were all out and every trace of men was still—nowhere were Bright Moon and Clear Wind to be found.
香火全無 (xiānghuǒ quán wú) "the incense-fires wholly gone." 人蹤俱寂 (rén zōng jù jì) "all trace of people silent." 那裡有 (nǎlǐ yǒu) "nowhere were there," interrogative 那 (nǎ).
The immortals said, "The two of them, we suppose, took advantage of our absence, made off with the goods, and fled."
拐了東西走了 (guǎile dōngxi zǒule) "made off with the things and left"—the company's first, cynical surmise.
The Great Immortal said, "What an absurd idea!
豈有此理 (qǐ yǒu cǐ lǐ) "how could there be such a principle!"—an idiom of indignant dismissal.
"Would men who cultivate immortality dare do so wicked a thing?
修仙的人 (xiū xiān de rén) "one who cultivates immortality." 壞心的事 (huàixīn de shì) "a deed of ill intent"—the master credits his boys with too much virtue.
"They must have forgotten to lock the gate last night and gone off to sleep, and are not yet awake this morning."
忘卻關門 (wàngquè guān mén) "forgot to shut the gate." 還未醒 (hái wèi xǐng) "not yet awake," 還 (hái) "still, yet" (not the alchemical 還 (huán)).
The Great Immortal's charity toward his attendants deepens the irony: dismissing the notion that cultivators would steal, he lands on the innocent explanation—they overslept—which is, grotesquely, half true. His refusal to think ill of the boys sets up the shock of the discovery to follow.
