五聲令牌 The Five-Signal Code
大仙道：「這一上壇，只看我的令牌為號：一聲令牌響，風來；二聲響，雲起；三聲響，雷閃齊鳴；四聲響，雨至；五聲響，雲散雨收。」行者笑道：「妙啊！我僧是不曾見。請了，請了。」大仙道：「这一上坛，只看我的令牌为号：一声令牌响，风来；二声响，云起；三声响，雷闪齐鸣；四声响，雨至；五声响，云散雨收。」行者笑道：「妙啊！我僧是不曾见。请了，请了。」
逐句解 Line by line
The immortal said, “Once I am up on the altar, just watch my command-tablet for the signals: at the first crack of the tablet, the wind comes;
這一上壇: 一 = yí before 上 (4th tone). 只看: 看 = kàn. 令牌為號: 為 = wéi (“to serve as the signal”); the 令牌 is the priest's ritual command-placard.
at the second crack, the clouds rise;
二聲響 “at the second sounding.” 雲起 “the clouds rise.”
at the third crack, thunder and lightning peal together;
雷閃齊鳴 “thunder and lightning sound as one.”
at the fourth crack, the rain arrives;
雨至 “the rain comes.”
at the fifth crack, the clouds disperse and the rain is done.”
雲散雨收: 散 = sàn, “to scatter, disperse.”
Pilgrim said with a laugh, “Splendid!
行者: 行 = xíng. 妙啊 “how fine!” — mock admiration.
We monks have never seen the like.
我僧是不曾見: 不 = bù before 曾 (2nd tone).
Please go ahead, please go ahead.”
請了，請了 “after you, after you” — exaggerated deference as the immortal is ushered to his own undoing.
The immortal, flattered into openness, spells out his entire method: a five-stroke code on the command-tablet governing wind, cloud, thunder, rain, and clearing. In disclosing it he hands Wukong exactly what he wanted — for the Great Sage will shortly go aloft to command the very deities the tablet is meant to summon, turning the immortal's own signals against him. Wukong's overdone courtesy (“after you, after you”) is the sound of a trap clicking shut, and the five signals here name in advance the four contest-rhapsodies — wind, cloud, thunder, rain — to come.
