In the myths and legends of China, what is the origin of the "ghost king"?

The word "Wang" in "Ghost King" does not represent the supreme position. The statue of the ghost king is naked, with red hair and fangs and a demon bell in his hand. It is ferocious and looks like a hag. He is associated with black and white impermanence, so his position is naturally not too high. But because he hangs the word "king", his position should be higher than that of ordinary ghosts, and he is about a leader like Mountain King. ⊙ Qing Pu Songling's Strange Tales from a Lonely Studio (Volume VI) and the derailed department introduced a ghost king who was in charge of the derailed department. There are two big stone tablets under his yamen hall, which are engraved with "filial piety (loyalty)" and "courtesy, righteousness and honesty" respectively. This ghost king is called "the ghost king with an empty stomach". He looks "curly hair and chapped back". If he is a person for hundreds of years, his nostrils are upturned, his lips are upturned, and he does not accept his teeth. From a master bookkeeper to a tiger head. There are more than ten waiters, half ugly and half evil. "Although this ghost king flaunts filial piety, faithfulness, courtesy, honesty and shame, he is actually an insatiable cruel guy. He stipulated that when his subordinates visited him, regardless of guilt or innocence, they should cut a piece of moustache meat (thigh meat) as a "statute". But "the rich can be bribed and redeemed"-as long as you send more money, you can avoid the pain of cutting meat. The ghost king here is a corrupt official. There are many names of the ghost king. According to the Bodhisattva Wish Book, only the great ghost kings in Hell and Jambu-Di^pa (Nanshan Buzhou is the world where human beings live) are: Wuji Ghost King, Evil Ghost King, Great Ghost King, White Tiger Ghost King, Blood Tiger Ghost King, Red Tiger Ghost King, Scattered Ghost King, Flying Ghost King, Lei Guang Ghost King, Spike Ghost King, Thousand-eyed Ghost King and so on. The ghost king is in charge of production, life, illness, risk, three-eyed ghost king, four-eyed ghost king, five-eyed ghost king, seven-mile lost king, seven-mile lost king, seven-mile fork king, seven-mile fork king, fake king, fake king, and so on, and there are thousands of little ghost kings.
