銀殿賜宴 The Demon's Feast
那國王卻傳旨，教光祿寺大排筵宴，謝駙馬救拔之恩；不然，險被那和尚害了。當晚眾臣朝散，那妖魔進了銀安殿。又選十八個宮娥綵女，吹彈歌舞，勸妖魔飲酒作樂。那国王却传旨，教光禄寺大排筵宴，谢驸马救拔之恩；不然，险被那和尚害了。当晚众臣朝散，那妖魔进了银安殿。又选十八个宫娥彩女，吹弹歌舞，劝妖魔饮酒作乐。
逐句解 Line by line
The king then issued a decree, having the Court of Imperial Entertainments spread a great banquet to thank the Consort for the grace of his rescue — for otherwise, he thought, that monk had all but done him harm.
光祿寺 is the Court of Imperial Entertainments, the government office whose actual job was state banquets — a real Ming institution, put here at a monster's disposal. 救拔 is to rescue, to pull someone clear of danger. Both instances of 那 are pointing nà; 教, "ordering," is jiào.
That evening, when the ministers had withdrawn from court, the demon entered the Silver-Peace Hall.
朝散, "court disperses," takes 朝 as cháo and 散 as sàn; 銀安殿 is the Silver-Peace Hall. 那 is pointing nà.
Eighteen palace maids and serving-girls were chosen besides — to pipe and strum, to sing and dance, and press wine on the demon in his revels.
宮娥綵女 are palace maids and adorned serving-girls; 作樂, to make merry, takes 樂 as lè. Eighteen of them. Count them, because the chapter will.
The chapter's bitterest irony arrives here. The whole machinery of a kingdom — its decree, its banqueting office, its finest hall, its eighteen maids — is turned to celebrating the demon and thanking him for saving the king from the pilgrim he has caged. The usurpation is complete: the monster is guest of honour where the saint is a prisoner.
Gathering eighteen maids to entertain him sets the scene, with grim deliberateness, for what comes next. The reader is shown the demon at his ease, surrounded by helpless attendants, precisely so that his reversion will land as hard as possible.
