In "Journey to the West", there is a fierce demon king, he will eat the king of a country and the peddlers and pawns, and then establish himself as the king there, in order to eat the meat of the Tang monks, he also co-opted the two nearby demon kings to join the gang, and willing to be a little brother, he is the king of the lion camel country, the golden-winged eagle.

Regarding the origin of the golden-winged roc eagle, Rulai made an introduction in the book: "Since the beginning of heaven and earth, all things have grown, the beasts are longed by unicorns, and the birds are longed by phoenixes. The phoenix had to be in harmony again, breeding peacocks and roc. ”
Later, Rulai was swallowed by the peacock, and had to come out of the peacock's back, rulai wanted to kill it and was persuaded by the Buddhas, saying that killing the peacock was like hurting its mother, so Rulai left the peacock in Lingshan and was named the Buddha's mother Peacock Daming King Bodhisattva, and thus Dapeng became Rulai's cheap uncle.

Since it is Dapeng, then why is it called the golden-winged Dapeng eagle, we will find in detail that the golden-winged bird, the Roc bird, and the eagle are actually three kinds of creatures, and the difference between them is also very large.

In Buddhist texts, the golden-winged bird belongs to a race called The Garoula, one of the eight branches of the Celestial Dragon, and is the mount of Vishnu, one of the three main gods of Hinduism, with a human-faced bird body, a bird-faced human body, and a full-bird shape. This bird feeds on the dragon (actually a snake) of Indian legend, which is said to eat five hundred small dragons a day, and after death, it is bathed in fire, leaving only a pure blue glass heart.

Peng is a native Chinese sacred bird, also known as Kunpeng, the Taoist classics "Liezi", "Zhuangzi" have described a similar kind of large bird, especially in Zhuangzi's "Getaway" is the most famous: "There is a fish in the north, its name is Kun, the size of the Kun, I don't know how many thousands of miles it is; transformed into a bird, its name is Peng, Peng's back, I don't know how many thousands of miles it is."

Later, when Buddhism spread to Middle-earth, it borrowed many Taoist texts, among which the translation of the Eight Heavenly Dragons translated the snake (Naga) as a dragon, and the Garou Luo as the golden-winged roc bird. But Dapeng always has only one image, that is, the bird shape, at most he has a fish shape when he is in the identity of the carp, there is no bird head or human head bird body image like Garou Luo, and in The lake of Poyang in Jiangxi, there are still fishermen who call the long body of the blue fish and grass carp and the grass carp, indicating that in the folk carp is synonymous with describing the particularly large fish.

Sun Wukong once had a brother called Peng Devil King when he was in the seven holy knots, and also took a Dao name called "Mixed Heaven Great Sage", and later Sun Wukong was arrested by the Heavenly Court, and the Peng Devil King was missing, but from the point of view that Sun Wukong did not understand the martial arts routines of the Golden-winged Dapeng Eagle, the Peng-devil King and the Golden-winged Dapeng Eagle should not be a breed.

And the eagle is a kind of carnivorous bird of prey, in Japanese often the eagle and vulture on a par with the vulture, but Chinese carving and vulture is still different, the eagle belongs to the king of the eagle, the king does not eat carrion, and the vulture is mostly based on carrion for a living, the impression of the Chinese people on the eagle is mostly Jin Yong's novel "The Legend of the Eagle Hero" and "The Eagle Hero" in the three large eagles, especially the eagle brother, the image is more into the wood three points, the largest existing carving in the world is the American horn carving, the maximum length of up to 102 cm, the wingspan of up to 224 cm, It is indeed a relatively strong bird of prey.

Combined with the description in "Journey to the West", the golden-winged Dapeng eagle should be a separate breed created by Wu Cheng'en, just like Sun Wukong, the Lingming stone monkey, which is the spiritual species between heaven and earth, only this one has no semicolon, so it is called the Golden-winged Dapeng Eagle, also known as Yuncheng Wanlipeng.

The traditional commentary novel "Say Yue Quan Biography" once said that Yue Fei is the reincarnation of the golden-winged Roc bird (Yue Fei Zi Pengju), and the Golden Wushu is the reincarnation of a poisonous snake, so they must have a fight in this life, of course, this is all far-fetched by folk artists, but it can be seen that the mixed image of the golden-winged Roc bird was already deeply rooted in the hearts of the people at that time, so It is also the general trend for Wu Cheng'en to include it in the book.
