Penghou, from China: what it is and what people believe

The Penghou is a tree spirit from Chinese folklore, described in early texts as a dog-like creature formed from the essence of wood and found inside a tree when it is felled. Chinese classics record it from about the third century, and Japan took it in as the monster Hōkō.

What it is

Penghou (彭侯, "drumbeat marquis") is a tree spirit of Chinese myth and folklore, a creature said to grow from the essence of wood inside an old tree. The oldest account makes it a tailless black dog; another gives it a dog's body with a human face. It comes to light only when the tree is cut down, and in the best-known tale the trunk bleeds as it falls. The stories are unsentimental: the creature inside is stewed and eaten, its flesh judged to taste like dog meat. A sixteenth-century Chinese medical compendium files the being among its drug entries, and Japan took the figure over as Hōkō, drawn among the country's illustrated monsters. The Penghou belongs to the lore of spirits said to live in timber.

Where it comes from

The earliest description is in the Baize tu (白澤圖, Diagrams of the White Marsh), a Chinese work of about the third century. It takes its name from Baize, a White Marsh spirit known from the Baopuzi, and the book survives only in part, matched to a Dunhuang manuscript catalogued as P2682. A second telling appears in the Soushenji (搜神記, In Search of the Supernatural), a collection of about the fourth century, whose story is set in the Wu Kingdom of the Three Kingdoms era (220–280). Li Shizhen then carried both accounts into his Bencao Gangmu of 1578, placing the creature in a chapter concerned chiefly with monkeys. From China the spirit crossed to Japan, where Toriyama Sekien drew it for the Konjaku Hyakki Shūi.

What it is for

The old books meet the Penghou as game rather than as a power to consult. What they record is its flesh. The Baize tu notes that the meat can be cooked; the Soushenji has Jing Shu stew the creature from the camphor tree and find it close to dog meat in taste. Li Shizhen's Bencao Gangmu of 1578, a work of drug lore, files the entry in a chapter given mostly to monkeys and grades the flesh as "sweet, sour, warm, and nontoxic". The entry reads as classification, a legendary animal sorted among the monkeys, not as a promise of cure.

Peoples and places

China holds the whole early record: a diagram book of about the third century, a story collection of about the fourth with its tale set in the Wu Kingdom, and Li Shizhen's medical compendium of 1578. Japan took the figure in next. There the same characters are read Hōkō, and the artist Toriyama Sekien gave the spirit a page in the Konjaku Hyakki Shūi, one of his collections of monster pictures, quoting the Soushenji story and adding the Baize tu's note that a thousand-year tree yields such beings. The same creature thus passes from a Chinese manual and tale, through a Chinese pharmacy, into Japanese illustrated books.

What people believe

Behind the tales sits an idea that wood can gather an essence over long years, and that this essence can take animal shape. A creature born of a tree's essence is the Penghou; when the tree has stood a thousand years, the Baize tu says, that essence becomes another being, the pig-like Jiafei. Age matters, and so does the tree's death: felling is what exposes the spirit, and in the Soushenji the cut wood bleeds, as a living body would. The creature inside may wear a human face on a dog's frame, a sign of something between beast and person. The story ends with the spirit cooked and eaten, yet the bleeding trunk keeps the sense that the tree was alive.

Compare and confuse

The Penghou's nearest kin is the Jiafei, named on the same page of the Baize tu: the essence of a tree a thousand years old, shaped like a pig, with flesh said to taste of dog. The two are separate spirits of wood, not one being under two names. Across the sea the same characters are read Hōkō, the name under which Japanese monster catalogues list it.

Today

The Penghou reaches the present as a figure in books. Sekien's Konjaku Hyakki Shūi keeps it in the Japanese monster canon, and the Kaii-Yōkai Denshō Database, a modern archive of yōkai lore, lists it under the name Hōkō. On the Chinese side, the classical accounts stay in print through translation: the Soushenji appeared in English from Stanford University Press in 1996, and Li Shizhen's compendium in a six-volume edition of 2003.

Questions people ask about Penghou

What is the Penghou?

A tree spirit from Chinese folklore. The old texts describe a creature formed from the essence of wood, found inside a tree when it is cut down. One account gives it the shape of a tailless black dog, another a dog's body with a human face.

Where do the stories come from?

From China. The spirit appears in the Baize tu of about the third century and the Soushenji of about the fourth, whose tale is set in the Wu Kingdom of the Three Kingdoms period. Li Shizhen recorded it again in his 1578 compendium of materia medica.

Is the Penghou dangerous to people?

In the tales the danger runs the other way. When Jing Shu fells a large camphor tree, a Penghou is found inside, and he stews and eats it. The texts treat the spirit as a creature to be caught and cooked, not as an attacker.

Why is it also called Hōkō?

Hōkō is the Japanese reading of the same characters, 彭侯. Under that name the spirit appears in the Konjaku Hyakki Shūi, Toriyama Sekien's collection of monster illustrations, where he retold the Chinese tale and added the note about thousand-year trees from the Baize tu.

What is the Jiafei?

A second wood spirit named in the Baize tu. The essence of a tree a thousand years old is said to become a Jiafei, which looks like a pig, and whose meat is described as tasting like dog meat.
