就是洞門 Eight Rules Knows The Door
八戒道:「你原來不曉得。我前年請他去時,先在洞門外相見。後被我說泛了他,他就跳下,去洞裡換衣來時,我看見他將身往水裡一鑽。那一股瀑布水流,就是洞門。想必那怪將我們包袱收在那裡面也。」八戒道:「你原来不晓得。我前年请他去时,先在洞门外相见。后被我说泛了他,他就跳下,去洞里换衣来时,我看见他将身往水里一钻。那一股瀑布水流,就是洞门。想必那怪将我们包袱收在那里面也。」

Eight Rules said: "So you did not know, after all.
Exactly nine graphs with the quote left open — the brief puts a nine-graph predication PAST the J2 threshold, so it stands as its own segment.
The year before last, when I went to invite him back, I met him first outside the cave door.
相見 xiāng, met each other — pypinyin bakes xiàng. The reference is to chapter thirty-one, when Eight Rules fetched Wukong back from exile.
Afterwards, when I had talked him round and he jumped down and went into the cave to change his clothes, I saw him take his body and dive straight into the water.
說泛了他 'talked him round', literally floated him along. 將身 uses 將 as the disposal marker, jiāng.
That single cataract of flowing water is the cave door.
Eleven graphs, and the answer to the question that defeated Sha Monk two passages earlier.
It must be that the monster has put our bundles away in there."
那怪 deictic nà and 那裡面 deictic nà — both this time, against the interrogative nǎ of 看那個.
Eight Rules supplies, casually and from memory, the one piece of information the chapter has been withholding since blk2. The waterfall is the door. He knows it because he once came to this cave to coax Wukong out of retirement and watched him dive through — a domestic detail from an old errand, retrieved now as the solution to a practical problem.
The chapter's pattern of useful knowledge arriving from unglamorous sources holds. The Bodhisattva could not tell the pair apart; the Jade Emperor's mirror could not; but Eight Rules remembers where the door is because he was there. Ordinary acquaintance keeps outperforming supernatural discernment, and the novel has not yet said so out loud.
你原來不曉得 also carries a small flick of superiority, which is entirely in character. Eight Rules has spent the chapter arriving late and being of no use, and this is his one moment of knowing something the others do not. He makes the most of it.
