雷公嘴和尚 The Monk With A Thunder Face
國王聞言，傳旨教宣。長老即引行者入朝。文武百官見了行者，無不驚怕。有的說是猴和尚，有的說是雷公嘴和尚。個個悚然，不敢久視。長老在階前舞蹈山呼的行拜。大聖叉著手，斜立在傍，公然不動。国王闻言，传旨教宣。长老即引行者入朝。文武百官见了行者，无不惊怕。有的说是猴和尚，有的说是雷公嘴和尚。个个悚然，不敢久视。长老在阶前舞蹈山呼的行拜。大圣叉着手，斜立在傍，公然不动。

The king heard it and gave the order that they be summoned.
教宣 is the formal order to have somebody called in to the presence, and 教 takes jiào throughout this project.
The elder at once led Pilgrim into the court.
引 is to lead somebody in, and Tripitaka goes first. The arrangement matters for what happens in the next three sentences.
The officers civil and military saw Pilgrim, and there was not one of them who was not startled and afraid.
無不 is a double negative used for emphasis — not one of them who was not. The court has already been described as neither worthy nor good, and its first collective act in the chapter is to be frightened of a monkey.
Some said he was a monkey monk; some said he was a monk with the face of the Thunder Duke.
雷公嘴 is the beaked, jutting face of the Duke of Thunder, and it is Pilgrim's standing epithet across the novel, usually in the fuller form 毛臉雷公嘴, hairy-faced and thunder-beaked. The two guesses are offered as alternatives, and both of them are right.
Every one of them shuddered, and none dared look long.
悚然 is the physical jolt of fear, the skin going cold. Eight characters, and they finish off the court's entire contribution to the scene.
The elder performed his obeisance before the steps, with the dance and the shout of hail.
舞蹈山呼 is the full court ritual: the prescribed dance of homage and the shouted acclamation that goes with it. Tripitaka performs it correctly and completely.
The Great Sage stood with his hands folded, leaning to one side, and openly did not stir.
And here is the refusal. 公然不動 — openly, he does not move. That word 公然 is what turns it from an oversight into a statement: Tripitaka has just gone through the whole ritual, and Pilgrim stands beside him at an angle with his arms folded and does not bow to the king. 傍 holds páng.
The court's reaction to Pilgrim gets four sentences and no dialogue with him at all. They look, they are frightened, they whisper two guesses at what he is, they stop looking. He does not speak and nobody speaks to him.
Then the two obeisances, set side by side without comment. Tripitaka does the dance and the shout, the whole prescribed article. Pilgrim folds his arms, stands crooked, and 公然不動 — openly does not move. That one word is what makes it a statement rather than an omission.
It is also a fair reading of the situation. This king had two cohorts of his own monks beaten to death on no evidence and has spent three years failing to look into it. The creature declining to bow is the one who solved it overnight.
