What is Yuan Shoucheng's real identity?

Yuan Shoucheng's real identity is actually "the Commissioner of Heaven".

Throughout the book Journey to the West, there are quite a few people who have broken the dogma, but the reconnaissance system is still quite backward even unconsciously! Many public officials in heaven, such as Kuimu Wolf, have been absent without leave for thirteen years, forced to marry into the world, and gave birth to a pair of children, but heaven knows nothing about it. However, the reaction to King Jinghe's little hands and feet, which were close to the Oracle, was too fast.

The bigger doubt lies in the trial of King Jinghe in heaven-as we all know, no matter how big the crime is, at least the criminals must be arrested before they can be convicted. For example, monkeys who directly rebelled, pigs who attempted rape, and sand monks who accidentally destroyed public property were all arrested first and then sentenced. As for those public officials and immortal mounts who have not yet been arrested, they cannot be convicted first.

As for King Jinghe, this process was completely overturned: not only the criminals were convicted without being arrested, but also the executors had already been appointed, and Yuan Shoucheng knew this process clearly, which was really incredible.
