面貌醜陋 Too Ugly to Question
館中有看館的人役，見他們面貌醜陋，也不敢問他，也不敢教他出去，只得讓他坐下不題。馆中有看馆的人役，见他们面貌丑陋，也不敢问他，也不敢教他出去，只得让他坐下不题。
逐句解 Line by line
There were staff in the guest house who looked after the place, and seeing how hideous their faces were, they dared not question them and dared not tell them to leave, so they had no choice but to let them sit down. Of that no more.
看 is kān here, to mind or keep watch over — the guest-house keepers — and not the kàn of looking at something, which is how the character is read everywhere else in this chapter. The sentence is built on a matched pair of refusals, 不敢問 and 不敢教他出去, dared not ask and dared not evict, which is a precise portrait of a junior official facing a problem above his pay. 不題, we say no more of it, is the storyteller putting one thread down to pick up another.
The chapter's first encounter with officialdom is a man deciding to do nothing, and the novel treats his cowardice with complete sympathy. He is not a fool; he is a caretaker who has three monsters in his lobby and no instructions.
The formula that ends the passage is the narrator changing the subject. It is the equivalent of a camera cutting away, and the story is about to follow Tripitaka indoors to meet the prince.
