久別未拜 Long Parted and Unvisited
這大聖整衣上前，深深的唱個大喏道：「長兄，還認得小弟麼？」牛王答禮道：「你是齊天大聖孫悟空麼？」大聖道：「正是，正是。一向久別未拜。適才到此問一女子，方得見兄。丰采果勝常，可賀也。」这大圣整衣上前，深深的唱个大喏道：「长兄，还认得小弟么？」牛王答礼道：「你是齐天大圣孙悟空么？」大圣道：「正是，正是。一向久别未拜。适才到此问一女子，方得见兄。丰采果胜常，可贺也。」
逐句解 Line by line
The Great Sage straightened his dress, stepped forward and made a deep obeisance with a loud salutation: "Elder brother, do you still know your younger brother?"
喏 is rě inside 唱喏, the salutation you call out aloud while bowing — not the nuò that means "yes, quite so." 長 is zhǎng at every position here, the elder-brother reading, against the cháng of 水長流 earlier in the chapter. 還 is hái, still.
The Bull King returned the courtesy and said, "Are you Sun Wukong, the Great Sage Equal to Heaven?"
答禮 is to return a salutation in the same form. The Bull King answers the bow before he answers the question, which settles the relation between the two of them before a word of quarrel is spoken.
The Great Sage said, "I am, I am. It is long since we parted and I have not paid my respects."
一向 shifts to yí before the falling tone of 向.
"Just now I came here and enquired of a woman, and so was able to see my brother."
一女子 takes yì before the dipping tone of 女, and 子 is the full zǐ. He mentions that he asked a woman for directions. He does not mention what happened next.
"Your bearing is finer than it was. I congratulate you."
A self-contained compliment, and pure flattery: your bearing is better than ever, congratulations. He has just observed privately that the man looks nothing like he used to.
The meeting is conducted with punctilious ceremony on both sides. The Great Sage straightens his clothes before he bows; the Bull King returns the salutation before he asks who is bowing. Two chapters of manoeuvring — a closed door, a forged fan, a chase through the pines, a woman screaming at a monkey — resolve for a moment into two old acquaintances observing the forms.
What the Great Sage does not do is more telling than what he does. He has been claiming the sworn brotherhood of five hundred years ago to everybody else in this arc — to the Rākṣasī at her door, to himself on the mountainside — and now that he is standing in front of the brother, he simply says 長兄, elder brother, and lets the word do the work. The claim has finally reached the one person entitled to confirm or deny it.
The compliment that closes the passage is flattery and it lands badly. He has just noted to himself that the Bull King's appearance has greatly changed in five hundred years; he now tells the man his bearing is finer than it was. The Bull King's first words in reply will be that he should spare his glib tongue.
