Chinese mythology terms in games are usually borrowed from an administrative system, not from a pantheon. Learn the twelve words you meet most often, what each one actually means, and the Western reading to drop before you argue about lore in a party chat.
Start with the summary, then read the entry you need. Every definition below is the general cultural term; how a specific game implements it belongs to that game's own guide.

These categories overlap in practice: one game may use a single word for all four, and some yao are written as sympathetic characters.
Diyu
di yu · underworld
Diyu is the Chinese underworld, run like a court: it reads your record, sets a sentence, then sends you back.
English UIunderworld / hell zone
Do not readIt as eternal punishment. Sentences end, records can be contested, and living relatives can influence the process through offerings and rites.
In gamesUsually a dungeon or a death zone, but the lore often keeps the paperwork: judges, ledgers, gates, and fixed terms of sentence.
Yanluo is one of ten underworld judges: he hears your case and sets the sentence.
English UIYama / King of Hell
Do not readHim as Satan or as a king of hell. He sits inside a bureaucracy with no single owner, and other courts handle other offences.
In gamesOften staged as a threatening boss; the accurate version is a magistrate with real authority, frequently shown behind a desk or a ledger rather than on a throne.
The Jade Emperor is the top administrator of heaven. He signs orders and receives reports from the gods below him.
English UIJade Emperor / Heavenly Emperor
Do not readHim as an omnipotent creator. He can be petitioned, misinformed, and occasionally overruled by higher cosmological tiers such as the Three Pure Ones.
In gamesUsually a final boss or a distant quest giver. The bureaucratic reading explains why his orders arrive as paperwork and why local deities matter more in daily play.
Yao means a non-human being that has transformed — usually an animal or a plant. It describes origin, not morality.
English UIdemon / monster
Do not readIt as a synonym for demon. Benevolent yao appear throughout Chinese fiction, and some cultivate toward immortality rather than prey on people.
In gamesMostly hostile mobs, but the category explains why certain yao are negotiable, recruitable, or bound by rules instead of simply killed.
Jing is the spirit inside a thing; in cultivation it also means refined essence.
English UIspirit / essence (also “weapon spirit”)
Do not readIt as a ghost. Gui is a dead person; jing is the animating spirit of something that may never have been human.
In gamesAppears as weapon spirits, beast companions, and collectible essences. The two senses are usually split across different systems, so check which one a tooltip means.
Mo is obstruction: the thing that blocks or twists cultivation. It covers inner demons and fallen practitioners.
English UIdemon / corruption
Do not readIt as a species, and do not treat it as a straight swap for demon. What matters is what the state does to a person's progress, not what kind of creature it is.
In gamesUsually a corruption meter, a berserk phase, or a faction of fallen cultivators. The common thread is loss of control rather than a monster type.
Shenlong is a dragon with an office: rain, a river, or a region to manage.
English UIdragon god / Dragon King
Do not readIt as a free-roaming monster or a god of everything. The post is assigned, limited, and revocable, which is why a drought can be a bureaucratic failure.
In gamesOften a raid boss; the bureaucratic reading explains why dragons keep domains, subordinates, and rules about when rain is permitted.
Nian is the New Year beast: it raids the village until noise, red paper and light drive it off.
Do not readIt as a dragon or as an ordinary raid boss. Nian belongs to one date on the calendar, and its defeat is the reason the holiday exists.
English UI“Nian”, “New Year beast”, “Lunar New Year boss”.
In gamesSeasonal event bosses, firecracker consumables and red-envelope rewards. If an event runs in January or February and involves noise, red or fireworks, Nian is usually behind it.
Meng Po is the underworld official who serves the forgetting soup, so the next life starts clean.
Do not readHer as a goddess of death or a boss who kills. She does not end life; she ends the memory of it, at the point where the sentence has already been served.
English UI“Meng Po”, “Lady of Forgetfulness”, “soup of oblivion”.
In gamesMemory-wipe mechanics, rebirth resets, and NPCs standing at a bridge or a gate. A game that keeps your memories through rebirth is deliberately breaking her rule.
Lunhui is the wheel of rebirth: you return in a new form, based on your record, not on forgiveness.
Do not readIt as resurrection, or as the same person coming back unchanged. Rebirth keeps the causal record and drops the identity.
English UI“reincarnation”, “rebirth cycle”, “samsara”.
In gamesNew Game Plus, rebirth systems and soul-bound progression. If a game promises you will keep your gear through rebirth, it is simplifying the cycle rather than reproducing it.
No. Diyu is a system of courts and sentences that end; hell in the Western sense is usually final. Games often borrow the imagery and drop the appeals process.
Are all yao evil?
No. Yao is a category of origin, not a moral judgment. Fiction regularly features benevolent yao, and games sometimes make them recruitable allies.
Is the Jade Emperor a god in the monotheistic sense?
No. He is the head of an administration with ministries, reporting lines, and higher tiers above him. Treat him as a chief executive rather than a creator.
Why do games show heaven as a government?
Because the source material describes one. Bureaucracy is the setting's default metaphor, which is why quests so often involve reports, seals, and jurisdiction.
