Why can Yuan Shoucheng figure out that King Jinghe was beheaded?

Yuan Shoucheng's real identity is "Commissioner of Heaven", and he is a fairy of heaven.

Yuan Shoucheng can know the jade emperor's orders because Yuan Shoucheng is a fairy who performs the tasks assigned by the jade emperor. Heaven and earth discuss Buddhist scriptures and arrange Buddhist personnel. The Monkey King, Pig and Friar Sand didn't kill them, but kept them for the scriptures. Everything is ready for the reincarnation of the golden cicada in the west, except a fuse that triggers the event.

This fuse was lit by Li Shimin. In order to convince Li Shimin that only Mahayana Buddhist scriptures can save his people, he must see the difference between heaven and earth with his own eyes. So Yuan Shoucheng was sent to the lower bound. They took advantage of the gambling character of the king of Jinghe River and performed a play, which led to a series of plots such as fortune telling, gambling and dragon cutting.

Extended data:

Fortune telling was a legal profession in ancient times, but most fortune tellers only lied about money. Most of the things they worked out were inaccurate, even if one or two things happened to make him right, it was just a coincidence. Because people cannot predict the future.

Yuan Shoucheng is very important in The Journey to the West. It was because of the bet with King Jinghe that Wei Zhi dreamed of beheading the Dragon King, which led to Li Shimin's wandering in the underworld and determined the principles and policies of learning from the scriptures. It can be said that without him, there would be no series of events that were learned later.

Journey to the West also made it clear that the Dragon King didn't know whether it would rain the next day. So when he bet, he thought he was a shoo-in. It was not until the next morning that the Jade Emperor issued a decree that he knew where and how much it would rain today. In other words, the news of Yuan Shoucheng is faster and more accurate than that of the Dragon King.
