逐句解 Line by line
Just as they were talking, the Provisions Officer arrived with his staff, moved the tables and chairs into place, and set out the meal.
調開 is to shift things apart and into position, and the novel uses the same word elsewhere for drawing troops away from each other — so it is a word about moving things where you want them, whether those are chairs or soldiers. 正說處, right at the point of speaking, is the standard cut: dinner arrives and stops the argument, which is how most arguments end.
At that master and disciples said nothing more, and each of them ate his meal.
The chapter's quietest sentence and one of its best. 各各, each and each, is the doubling that means one by one, separately — four men eating in silence at the same table. 卻不言語, and then said nothing, closes the quarrel without resolving a word of it.
The argument is not settled. Dinner arrives and everyone stops talking, which is both funny and exactly what happens.
The image of the four of them eating in silence is one the novel returns to whenever a family row runs out of road. Nobody apologises, nobody concedes, and the food is good.
