一壁廂嚴緊 All Was Kept Close
那時群妖將唐僧三眾收藏在後;把馬拴在後邊;把他的袈裟、僧帽安在行李擔內,亦收藏了。一壁廂嚴緊不題。那时群妖将唐僧三众收藏在后;把马拴在后边;把他的袈裟、僧帽安在行李担内,亦收藏了。一壁厢严紧不题。
逐句解 Line by line
At that the crowd of fiends stowed the Tang Monk and the three of them away at the back;
The source cuts one sentence into three disposal clauses with semicolons. They are not strictly parallel — this one carries a time word and a named subject that the other two drop, and the last adds a clause the first two have no answer to — so the three stand apart.
tethered the horse behind;
Six graphs, the shortest thing in this stretch. The horse is the white dragon prince, which the chapter says outright much later; the demons tie it up round the back and take no further interest in it whatever.
and put his cassock and monk's cap into the luggage-pack, and stowed those away too.
The cassock and the cap go into the luggage-pack rather than onto a demon, which is why they are still there to be stolen back later. 行 is xíng in 行李 and 擔 is dàn, the carried load rather than the verb. This is the second place in the chapter where the automatic reading offers háng and is wrong — and it got the very same compound right four hundred and thirty-four graphs earlier.
On that side all was kept close, and no more of it.
不題 is the storyteller putting a thread down: no more of this for now. It is the formula that lets the narrative cut away, and the next thing the reader hears comes from inside a pair of cymbals.
Four short clauses of housekeeping, and two of them matter a great deal later. The cassock and the monk's cap go into the luggage-pack, and the horse is tied up behind rather than eaten, so both come through the chapter in usable condition.
The passage also shuts the frame on the disaster. 嚴緊 is the demons' side of the story sealed up tight, and 不題 is the teller's own hand laid on top of it.
