逐句解 Line by line
That blockhead has no shortage of cleverness where his mouth is concerned. He stepped forward, made a great bow with a shout, and said, "Master, my brother just now said there are households in the village ahead feeding monks.
喏 is rě — a 大喏 is a bow made with a loud formal cry, the sort of salute a soldier or a servant gives, and Bajie performing one is already overdoing it. 吃嘴的見識, cleverness of the mouth, is the narrator giving him credit for the one form of intelligence he reliably shows.
Now look at this horse. He is bound to put the household out, wanting grass and wanting feed, and would that not be a trouble to them?
The excuse is a small masterpiece. It is about the horse, it is about being considerate to strangers, and it does not mention food once. 草 and 料 are grass and grain — the two things a horse is fed, itemised for realism.
Pilgrim challenged him to find a way and he has found a very good one. The lie is considerate, practical, and entirely about someone else's convenience.
The narrator's phrase for it is exact: cleverness where his mouth is concerned. Bajie is not stupid. He is intelligent in one direction only, and this is that direction working at full stretch.
