良宵一宿 Meals On The Road
那夥妖魔同心合意的侍衛左右，早晚慇懃。行經三十里獻齋，五十里又齋，未晚請歇，沿路齊齊整整。一日三餐，遂心滿意；良宵一宿，好處安身。那伙妖魔同心合意的侍卫左右，早晚慇懃。行经三十里献斋，五十里又斋，未晚请歇，沿路齐齐整整。一日三餐，遂心满意；良宵一宿，好处安身。
逐句解 Line by line
That crowd of monsters attended on either side with one mind and one purpose, diligent from early to late.
慇懃 — attentive and painstaking in service. 侍衛 is to attend and guard, the word for a bodyguard.
Thirty li on they served a meal; fifty li on, another; before dusk they asked him to rest; and all along the road everything was in good order.
獻齋 — to present a monastic meal. 齊齊整整 doubles both characters: everything neat and in place. Thirty lǐ is about seventeen kilometres.
Three meals a day, and everything as the heart could wish;
遂心滿意 — the heart followed and the wish filled, two expressions of the same contentment.
a fine night's lodging, and a good place to lay the body down.
處 reads chù, a place. 一宿 takes xiǔ for a night's stay, not the sù of lodging as a verb.
The trap is comfort, and the novel describes it with real warmth. A meal at thirty li, another at fifty, a rest called before dark, three meals a day and a good bed at night. After seventy-five chapters of hunger and sleeping rough, the pilgrims are being looked after properly for the first time in a very long while.
That is what makes it work. There is nothing to see through. The service is genuine, the food is real, the shelters were built to a plan and staffed with cooks. The third fiend's stratagem does not require anybody to be deceived about anything except the purpose, and the purpose is invisible.
The prose slips into pairs and doublings — one mind and one purpose, neat and in order, the heart followed and the wish filled — and the rhythm is soothing on purpose. The narrator has already told us that grief is coming. He now spends four segments describing how pleasant the road is, which is a colder piece of craft than anything the demons have managed.
