When first reading Diyu, do not start only from horror atmosphere
Diyu is often reduced to gloomy scenes: black gates, ghost fire, punishments, underworld rivers and judges' desks. These images are useful, but they are not the reading path. What readers need first is the process: who receives the dead, where souls go first, how judgment unfolds, what each of the Ten Kings handles, and how souls finally enter rebirth or punishment.
Once the process is clear, the roles stop being chaotic. Black and White Wuchang are not random ghost officers; judges are not isolated spooky figures; City Gods are not ordinary underworld clerks. They connect respectively to escorting, judgment, local governance, moral records, Buddhist hell ideas and folk funerary imagination.
The first Diyu map should explain the process
Death and guidance
Black and White Wuchang, ghost officers and local City Gods often perform receiving or escorting functions. Accounts differ across stories and should be explained by text.
Judges and King Yanluo
Judges handle records, checking and judgment wording; King Yanluo or the Ten Kings handle judgment. Here folk stories, religious concepts and fictional dramatization must be separated.
Ten Kings belief
The Ten Kings of Hell should be organized by court order, judgment content, punishment imagery and rebirth nodes, not listed by name alone.
Rebirth and reincarnation
Naihe Bridge, Meng Po and rebirth recur in folk stories and modern adaptations, and need to be layered apart from Buddhist rebirth concepts and folk narrative.

Read Diyu roles by function
Ten Kings of Hell
They are not ten randomly listed ghost kings, but core nodes in the judgment process. Later long articles will organize them by court order, duties, story sources and common misunderstandings.
Judges
Judges are often linked with the Life-and-Death Register, moral records and judgment documents. The site should explain what they do in stories, not merely label them as underworld officials.
Black & White Wuchang
Black and White Wuchang are best read in the guidance and soul-arrest stage. Their names, images and personalities vary by region and work, so those variations should be marked separately.
City Gods and Earth Gods
The City God connects local urban protection, underworld judgment and soul management. He is not merely a Diyu figure, but also belongs to folk pantheons and local belief.
Diyu sources must be layered, or they contradict one another
The Diyu system is layered by nature. Buddhism brought ideas of hells, rebirth, Ksitigarbha and the Ten Kings; Daoist and folk belief supplied underworld offices, City Gods, Earth Gods and ghost officers; fiction, opera and film rewrote them into more story-friendly underworld administrations. This site keeps those sources separate instead of forcing them into one official institution.
Planned Diyu article sequence
- Overview of the Ten Courts: the ten courts, Yama kings, judgment and rebirth process.
- Black and White Wuchang: guidance, soul arrest, folk images and modern adaptations.
- Judges and the Register of Life and Death: records, judgment documents and accounts of good and evil.
- City God: local urban guardian, underworld functions and folk worship.
- Meng Po and Naihe Bridge: the exit to rebirth, forgetting narratives and later literary imagery.
