In a moment Eight Rules's face changed colour, Sha Monk's eyes streamed with tears, and froth came from the Tang Monk's mouth.
⚠ 吐 is tù here, and the distinction matters. The character has two old bands: 康熙 gives 他魯切 for tǔ, glossed 寫也 and 出也，舒也 — putting something out on purpose — and 湯故切 for tù, glossed 歐也, to bring up. This chapter uses both. The spiders spitting silk are tǔ; a poisoned man frothing is tù. Three symptoms in three clauses of equal length, one each — the prose is a checklist.
None of them could stay upright, and they fainted and fell to the ground.
倒 is dǎo, to fall over, not dào, to invert or pour. Of the nine in this chapter, eight are this falling band and only one — 倒栽蔥, to go head-first like a leek planted upside down — is the other. 坐不住, could not keep sitting, is a verb-plus-bu-plus-complement of exactly the kind that turns 得 into de a few lines from now.
Twenty-three characters for the poisoning and it is done in three clauses of the same length: face, eyes, mouth. The narrator has not raised his voice or reached for a single adjective. He simply lists three men and what is happening to each of them, in the order you would see it from across a room.
The restraint is doing something specific. This chapter has spent hundreds of characters on the manufacture of this poison, its price, its dosage and its carriage. Now it arrives, and the arrival gets fewer characters than the recipe's opening couplet. Everything was in the preparation; the event itself is over in a breath.
And the fourth man is not mentioned. He has a cup in his left hand, covered with his right, and he is still watching.
