The temple they arrived at was resplendent, but the title Sun Wukong received was far less so. His job was to watch after the livestock. He performed diligently until he learned exactly how irrelevant his position was, after which he raged and returned to the kingdom he ruled.
The Monkey King’s subjects celebrated his return with massive feasts and were excited to hear tales of his exploits. When he explained the indignity he suffered by the insolent rulers of the temple, they were confounded that their leader’s tremendous power had been ignored so blatantly.
On the other hand, when the officials at the temple reported Wukong’s departure the Supreme Sage was livid. The monkey had refused his mercy in a petulant fit, the nerve! The Sage issued the order he should have originally given.
