Misconceptions About Monkey’s Staff and the Milky Way Galaxy

Last updated: 02/06/2021

A common misconception on the internet is that Sun Wukong’s magic staff was originally used to hold down the Milky Way (fig. 1), suggesting that, since the immortal can effortlessly wield the weapon, he is strong enough to lift the weight of a galaxy. This misconception usually pops up in forums and battle wikis during debates on the lifting strength of particular mythological or fictional characters. It ultimately stems from a mistranslation in the widely read W.J.F. Jenner edition. [1] The passage in question reads:

The piece of miraculous iron that anchors the Milky Way in place has been shining with a lovely rosy glow for the last few days, and creating a most auspicious atmosphere (Wu and Jenner, 2001, p. 55) (emphasis mine).

However, the original Chinese reads:

我們這海藏中,那一塊天河定底的神珍鐵,這幾日霞光艷艷,瑞氣騰騰… (Wu, 2001, p. 32) (emphasis mine).

Wǒmen zhè hǎi cáng zhōng, nà yīkuài tiānhé dìng dǐ de shén zhēn tiě, zhè jǐ rì xiáguāng yàn yàn, ruì qì téngténg

The problem lies in the partial mistranslation of the characters 天河定底 (Tiānhé dìng dǐ). Tianhe is the Chinese name for the Milky Way, while ding di means to “fix or set the depth or base of”. This refers to setting a fixed measurement for the “Heavenly River” and has nothing to do with anchoring or weighing down anything.

The far more accurate Anthony C. Yu translations reads:

Inside our ocean treasury is that piece of rare magic iron by which the depth of the Heavenly River is fixed. These past few days the iron has been glowing with a strange and lovely light (Wu and Yu, 2012, p. 135) (emphasis mine).

Most importantly, the novel is quite clear on how much the staff weighs:

Immediately adjacent to one of the hoops was the inscription, “The Compliant Golden-Hooped Rod. Weight: 17,550 pounds (Wu and Yu, 2012, p. 135). [2]

A nine ton pole would have zero effect on a galaxy that weighs one trillion solar masses.

I’ve written a follow up discussing Monkey’s greatest feat of strength.


Update: 02/06/21

I have written an article that discusses the magic powers of the staff. These include the ability to shrink and grow, control the ocean, astral project and entangle with Monkey’s spirit, multiply endlessly, pick locks, and transform into various objects. It also has sentience to a certain degree.



1) This is the first edition I read as a youngster.

2) Anthony Yu’s original translation says “13,500 pounds”. However, the Chinese version uses jin (斤), known in English as “catty.” The catty and pound are two different measures of weight, the former being heavier than the latter. Therefore, the English text has been altered to show this. The catty during the Ming Dynasty when the novel was compiled equaled 590 grams (Elvin, 2004, p. 491 n. 133), so 13,500 catties would equal 17,550 lbs.

“That Piece of Rare Magic Iron”: The Literary and Religious Origins of the Monkey King’s Staff

Last updated: 02/06/21

Sun Wukong (孫悟空) the Monkey King (fig. 1) is one of the most enduring characters of East Asian literature and folklore. Much ink has been spilled in the analysis of the novel in which he appears, the highly popular Ming Dynasty (1368-1644) classic Journey to the West (Xiyouji, 西遊記) (1592). For instance, Anthony C. Yu’s updated translation includes an almost 100 page introduction highlighting the historical background and religious and literary influences of the novel.[1] The origins of Monkey has also been discussed at great length.[2] However, no scholars have attempted to trace the origins of his magical iron staff, the most recognizable part of his iconography. In this paper, I propose that the weapon is an amalgam of ringed staves carried by religious monks and iron staves carried by martial monks. Both are featured in Chinese fiction and religious-inspired martial arts legends. My hope is that this information will be both useful to researchers and interesting to fans of Ol’ Monkey.

1. Literary description

The staff first appears in the third chapter when Monkey goes to the underwater kingdom of Ao Guang (敖廣), the Dragon King of the Eastern Sea, looking for a magic weapon to match his supernatural strength and martial skill. When all of the traditional magic weapons—a scimitar, a fork, and a halberd weighing thousands of pounds each—fail to meet his standards, the dragon queen suggests to her husband that they give Sun “that piece of rare magic iron” taking up space in their treasury. She claims that the ancient shaft had started producing heavenly light days prior and proposes that the monkey is fated to own it. The novel never explains how the pillar was made, only that it was originally used by Yu the Great (大禹), a semi-historical Chinese emperor, to measure the depths of the world flood during times immemorial.[3]

The staff is initially described as a pillar of black iron twenty feet in height and the width of a barrel. It is only when Monkey lifts it and suggests that a smaller size would be more manageable that the staff comply with his wishes and shrinks. This is when Sun sees that the weapon is banded with a gold ring on each end, as well as the inscription along the body reading: “The Compliant Golden-Hooped Rod. Weight: thirteen thousand five hundred catties” (如意金箍棒重一萬三千五百斤).[4] The inscription indicates that the staff follows the commands of its owner, shrinking or growing to their whim, and that it is immensely heavy, weighing 17,550 lbs.[5] One particular passage from the novel best summarizes the abilities of Monkey’s staff:

[Sun Wukong] held the treasure [the staff] in his hands and called out, “Smaller, smaller, smaller!” and at once it shrank to the size of a tiny embroidery needle, small enough to be hidden inside the ear. Awestruck, the monkeys cried, “Great King! Take it out and play with it some more.” The Monkey King took it out from his ear and placed it on his palm. “Bigger, bigger, bigger!” he shouted, and again it grew to the thickness of a barrel and more than twenty feet long. He became so delighted playing with it that he jumped onto the bridge and walked out of the cave. Grasping the treasure in his hands, he began to perform the magic of cosmic imitation. He bent over and cried, “Grow!” and at once grew to be ten thousand feet tall, with a head like the Tai Mountain and a chest like a rugged peak, eyes like lightning and a mouth like a blood bowl, and teeth like swords and halberds. The staff in his hands was of such a size that its top reached the thirty-third heaven and its bottom the eighteenth layer of Hell. Tigers, leopards, wolves, and crawling creatures, all of the monsters of the mountain and the demon kings of the seventy-two caves, were so terrified that they kowtowed and paid homage to the Monkey King in fear and trembling. Presently he revoked his magical appearance and changed the treasure back into a tiny embroidery needle stored in his ear.[6]

Sun later uses this powerful weapon in his war against heaven when they don’t recognize him as a full-fledged god. He is so powerful that the Jade Emperor (Yuhuangdi, 玉皇帝) of heaven has to ask the Buddha to intervene. After being imprisoned beneath a mountain range for 500 years, Monkey is eventually released and takes the tonsure as a Buddhist monk. He is charged with the protection of the monk Xuanzang (玄奘) on a journey to retrieve Buddhist scriptures from India. He uses his staff to battle all sorts of monsters, spirits, and rogue gods along the way.

1.1 Literary antecedent

The earliest depiction of the staff appears in the oldest edition of Journey to the WestThe Story of How Tripitaka of the Great Tang, Procures the Scriptures (Da Tang Sanzang qujing shihua, 大唐三藏取經詩話), published during the late Song Dynasty (960-1279).[7] In the second chapter, Sun takes Xuanzang to heaven to meet Vaisravana, the Mahabrahma Deva.[8] After the monk impresses the heavenly retinue with his lecture on the Lotus Sutra, Monkey is given a cap of invisibility, an alms bowl, and a golden ringed monk’s staff (khakkhara) (fig. 2) as magical weapons against the evils they will face on their journey to India. Sun later uses the staff in a battle with a white-clad woman who transforms into a tiger demon. He changes the staff into a titanic, red-haired, blue-skinned yaksha with a club, showing that the predecessor of the Compliant Rod has more magical abilities in comparison.[9]

A weapon that predicts the Compliant Rod is mentioned early on in The Story. Monkey describes how the Queen Mother of the West (Xiwangmu, 西王母), a demon-like goddess originally worshiped in ancient China, had him flogged with an “iron cudgel” (tiebang, 鐵棒) for stealing ten peaches from her heavenly orchard. He later borrows the cudgel to use in tandem with the monk’s staff to punish nine dragons.[10] The golden rings (jinhuan, 金環) on the monk’s staff most likely influenced the golden hoops (jingu, 金箍) on the weapon from the Ming version.[11] Therefore, both staffs from the Song version were combined to create the Compliant Rod.

2. Origin

Many scholars believe that Sun Wukong was influenced by the monkey god Hanuman from the Indian epic the Ramayana (3rd-century BCE). The two have many textual similarities,[12] but weapons are not among them. Despite his traditional iconography, the Ramayana doesn’t mention Hanuman wielding a mace. His later association with this weapon may have been influenced by two sources. First, the novel portrays him as using his great strength to wield heavy objects, both natural and man-made, as blunt weapons.[13] Second, he was closely associated with yaksha demons in other great Hindu classics like the Mahabharata (4th-c. BCE to 4th-c. CE). Early Buddhist sutras mention yakshas wielding maces.[14] One such individual is the Yaksha King Kubera-turned-Buddhist deity Vaisravana, who later makes appearances in the The Story and Journey to the West.[15] The mace was a fixture of Hanuman’s iconography by at least the 12th-century since dynastic coins from this time feature him holding the weapon.[16] However, the association between the two surely took place well before this if the iconography was common enough to stamp on coins. Yet, I am not inclined to speculate that stories of his mace eventually made it to China. Monkey’s weapon may have just been influenced by Buddhist yakshas as well.

As previously mentioned, Sun becomes a Buddhist monk after being released from imprisonment. Meir Shahar explains that the staff was the emblem of the monk. It was a part of the eighteen items that Indian Buddhist monastic law required that they carry with them on the road.[17] In China, there were two different kinds of monks (with some overlap), the lesser known martial type charged with protecting the religious community (sangha) and the more widely known religious type living in cloisters and proselytizing on the road. Both groups carried different kinds of staves. The martial monks wielded the wooden or iron kind. The former was chosen for its diminished capacity to kill unlike edged weapons,[18] while the latter was used for killing during times of war.[19] The religious monks carried the aforementioned ringed kind.

Fig. 3 – The 1517 Shaolin stele featuring Vajrapani (larger version).

The martial monks of the Shaolin Monastery, for example, are famous for their skill with the staff. It’s interesting to note that they venerate the yaksha-turned-Buddhist protector deity Vajrapani as the progenitor of their staff method. A stele erected in 1517 tells the story of how the deity, disguised as a lowly kitchen worker, grew to titanic proportions and wielded a fire poker as a makeshift staff to defend the monastery against rebels during the late Yuan Dynasty (1271-1368) (fig. 3).[20] Buddhist iconography traditionally depicts Vajrapani wielding a mace in defense of the Buddha and his teachings (the dharma). [21] The Shaolin monks may have changed his mace to a staff because this was the blunt weapon with which they wielded in defense of the religious community and, by extension, the Buddha and his Word,[22] as well as in defense of China against rebels and foreign invaders. Shahar suggests that “martial deities such as Vajrapani exonerated the monks from their responsibility for the creation of military techniques.” He continues, “In this respect their legends could be read as Buddhist apologies for the monastic exercise of violence.”[23] Therefore, I suggest that Monkey’s iron staff from the The Story is based on the staves used by martial monks. After all, Sun is a Buddhist warrior just like the monks of Shaolin, and he uses his iron staff to meter out punishment and death just like Vajrapani and his mace.[24]

The ringed staves were known as “xi staves” (xizhang, 錫杖; Sk: khakkhara), which early medieval Chinese documents describe as being decorated with six to twelve metal rings. These rings were designed to make a clanging noise (xi, 錫) to not only scare away any poisonous animals on the road, but also to alert possible donors to the monk’s presence. Noted Buddhist personages and deities were often portrayed as having the same ringed staff and alms bowl given to Monkey in The Story.[25] For instance, a popular story circulating during the Song involves Mulian (目連; Sk: Maudgalyayana), a close disciple of the Buddha, using the magic power of the aforementioned objects to free his deceased mother from the torments of the underworld.[26]

3. Conclusion

The Compliant Rod from Journey to the West is based on two staves from an earlier Song-era edition of the story. The first is a golden ringed monk’s staff given to Monkey by the deva Vaisravana (among other objects) as a magical weapon to protect the monk Xuanzang. The second is an iron staff procured by Monkey from the Queen Mother of the West in order to punish nine dragons. The former is based on ringed staves historically carried by religious monks while proselytizing on the road. The ringed staff is among the magic items used by Buddhist personages and deities in Song-era stories. The latter is based on wooden and iron staves historically used by martial monks to defend both the Buddhist community and China from rebels and foreign invaders. Martial monks, such as those from Shaolin, attributed their staff skills to mace-wielding yaksha demons-turned-Buddhist protector deities as way of excusing their use of violence. Likewise, Monkey’s use of violence is excused because he wields his staff in protection of his master Xuanzang. In the end, both staves were combined in the Ming version. The golden rings of the ringed staff were transposed onto the iron staff. The Compliant Rod therefore inhabits the worlds of heaven and hell, religion and combat, salvation and punishment.

The staff influenced the weapon used by the humanoid alien Son Goku (himself based on Sun Wukong),[27] the main character of the Dragon Ball franchise. It is named Nyoi Bo, the Japanese transliteration of Ruyi bang (如意棒, “Compliant Rod”), and is commonly called “Power Pole” in English language media.[28] The staff is given to him as a child by his grandfather Gohan, a human who adopts and teaches him martial arts.[29]

Update: 06/4/14

I was mistaken when I stated that the novel doesn’t explain how the staff was made. The 75th chapter has a long poem describing the history of the weapon. The first few lines read:

The rod of steel nine cyclic times refined
Was forged in the stove by Laozi himself.
King Yu took it, named it “Treasure Divine,”
To fix the Eight Rivers and Four Seas’ depth.
In it were spread out tracks of planets and stars,
Its two ends were clamped in pieces of gold.
Its dense patterns would frighten gods and ghosts;
On it dragon and phoenix scripts were drawn.
Its name was one Rod of Numinous Yang,
Stored deep in the sea, hardly seen by men

However, instead of reflecting the actual history of the staff (within the novel’s fictional universe), I think this is an example of how character’s boast about their weapons in a bid to “one-up” their opponents. It’s like saying, “My weapon is more prestigious than yours, so you have no chance of beating me.”

I wrote a sister blog to this entry a few days ago that describes additional influences of the staff. It can be read here:


Update: 12/30/14

I just posted the third and final installment of my investigation on the history of Monkey’s staff. It can be read here.


Update: 09/10/16

I noted in a previous entry (06-4-14) that a poem in the 75th chapter states the staff was created by Laozi in his oven. A later poem in the 88th chapter notes that it was made by Yu the Great:

An iron rod forged at Creation’s dawn
By Great Yu himself, the god-man of old.
The depths of all oceans, rivers, and lakes,
Were fathomed and fixed by this very rod.
Having board through mountains and conquered floods,
It stayed in East Ocean and ruled the seas,

Update: 02/06/21

I have written an article that discusses the magic powers of the staff. These include the ability to shrink and grow, control the ocean, astral project and entangle with Monkey’s spirit, multiply endlessly, pick locks, and transform into various objects. It also has sentience to a certain degree.
