假變四身 The Four Counterfeits
沙僧又告道:「這妖又假變一個長老,一匹白馬;又有一個八戒挑著我們包袱,又有一個變作是我。我忍不住惱怒,一杖打死,原是一個猴精。因此驚散,又到菩薩處訴苦。沙僧又告道:「这妖又假变一个长老,一匹白马;又有一个八戒挑着我们包袱,又有一个变作是我。我忍不住恼怒,一杖打死,原是一个猴精。因此惊散,又到菩萨处诉苦。

Sha Monk further reported: "This fiend had also falsely conjured an elder and a white horse;
The fiend has not merely copied Wukong; he has been recruiting. 長老 takes zhǎng, an elder, the honorific for a senior monk — meaning a false Tripitaka. The list is broken here by the semicolon in the source and kept in two parts, because its members get worse as it goes.
and there was another Eight Rules shouldering our bundles, and another changed into the likeness of me.
挑著: 挑 is tiāo, to carry on a shoulder pole, with 著 as zhe, the ending that keeps the carrying going. A few lines further on the same 著 will mean "set someone to do a thing" and read zhuó.
I could not contain my rage, and with one blow of my staff I killed him — and he turned out to be a monkey-sprite.
Killed, the false Sha Monk turns back into a monkey. 原是一個猴精 — it was a monkey-sprite all along — and this will matter: the counterfeits are made from the impostor's own plucked hairs, exactly the way Wukong makes his.
At that the rest scattered in fright, and I went again to the Bodhisattva to pour out my grievance."
驚散 takes sàn, to scatter; 菩薩處 takes chù, the Bodhisattva's place.
The list of counterfeits is the chapter's most concrete piece of evidence, and nobody in the story draws the obvious inference from it. The false Pilgrim has not merely copied Wukong; he has staffed an entire replacement pilgrimage — a Tripitaka, a horse, an Eight Rules, a Sha Monk — and put it on the road west. His ambition is not to displace one monkey. It is to finish the journey.
The list gets worse as it goes, which is why it resists being run together into a single unit. It begins with an elder and a horse, adds an Eight Rules carrying the baggage, and ends at 又有一個變作是我 — and one turned into me. Sha Monk saves himself for last, and the shock of the sentence is that the speaker has met his own double.
原是一個猴精 is the detail that will eventually explain everything. The false Sha Monk, struck dead, reverts to a monkey, because he was never a person at all but a hair transformed — the very trick Wukong uses himself. Whatever the impostor is, he has Wukong's techniques as well as his face.
