Readers may wonder where I get my inspiration to write articles. Most of the time I seek to answer a question that pops up while reading a book or researching a subject, leading to a subsequent paper on what I learned. Other times, I simply stumble across something online. A prime example of this is the “White Ape Perfected Man” (Baiyuan zhenren, 白猿真人), a rare folk Taoist deity that I recently learned about from Facebook. He is depicted with long hair (sometimes with ear-pressing tufts) and a golden fillet, linking him to Chinese opera depictions of military monks (wuseng, 武僧) (Bonds, 2008, pp. 177-178), thus signaling his position as a martial deity. A headdress with lingzi (翎子) feathers sometimes adorns his crown. His visage ranges from welcoming to fierce and from human to more primate-like. He wears a golden suit of armor and sits in a kingly fashion with the right knee resting on the seat, exposing the bottom of his foot to the viewer. This armor is sometimes draped in a colorful ritual cape. His left arm is usually bent at the elbow and the hand is clenched in a fist (or two-finger shooting mudra) or holds an immortal peach at the chest, while the other is held high and contains a fly whisk or staff. This iconography is shockingly similar to religious depictions of Sun Wukong as the “Great Sage Equaling Heaven” (Qitian dasheng, 齊天大聖). In fact, the two deities are nearly indistinguishable apart from the ape sometimes having white hair and a white face. But this isn’t always a good indicator, though, as one Fujian tradition features a brother of the Monkey King with a white face. And other times, statues of the white ape might be plain wood or even bronze, thereby erasing any signifying color. But the best clue to his identity appears to be the combination of the fist at the chest and a raised foot while in a seated position, what I call the “fist over foot motif” (fig. 1 to 4).
I’ve previously written about magical white apes (gibbons) in relation to Tang-era Chinese literature, primate-based martial arts, and the fictional origin of Sun Wukong. I’ve even archived an entire book on the subject which surveys historical references, poems, folktales, and art spanning over 3,000 years from the Zhou to Qing dynasties. I would like to supplement this material by writing an article about the White Ape Perfected Man and his appearance in vernacular fiction and Taoist scripture. I suggest his iconography was directly influenced by Sun Wukong based on a centuries-long association between the two magic primates in popular literature.

I. Religious Story
I traveled to the Sun Bin Shrine of Hongde Temple in Yingge District, New Taipei, Taiwan (Yingge Hongde Gong Sun Bin Miao, 鶯歌宏德宮孫臏廟) (fig. 5) to gather material for this article. Unfortunately, the temple’s statue of the White Ape Perfected Man (fig. 6) was out for repairs on the day of my visit. But I collected information about the deity from the temple’s history book (fig. 7). The ape god is associated with Sun Bin (孫臏, d. 316 BCE) (fig. 8), a deified military strategist of the Warring States period, and is revered as a transmitter of divine knowledge.  A rough translation of his religious story follows:
“The White Ape Steals a Peach and Offers a Heavenly Book” (Baiyuan toutao xian tianshu, 白猿偷桃獻天書)
According to legend, when Sun Bin was studying military arts under Master Ghost Valley (Guigu xiansheng, 鬼谷先生), he opened a plot of uncultivated land on the side of Yunmeng Mountain (Yunmeng shan, 雲夢山) and grew a peach orchard with big, fleshy, and delicious fruits using his teacher’s method. At the foot of the mountain lived a mother and son who depended on each other. The son looked like a monkey because his body was covered with white hair, and so he was known as the “Little White Ape” (Xiao baiyuan, 小白猿). His mother was constantly sick and occasionally dreamed of a transcendent pointing and saying, “Eat the immortal peaches on Yunmeng Mountain and your illness will be cured”.
The white ape was a filial son, and so he went to steal a peach for his mother but lost his way. Sun caught the boy and asked him why he would steal from the orchard. Once he heard of the ape’s sick mother, he gave him the peach. The mother ate the fruit and recovered. In return, the white ape gave Sun a heavenly book of military strategy (bingshu, 兵書) passed down from his ancestors, saying, “Thank you for your life-saving grace”.
Another version of the story states the Yunmeng peach was so famous for its large size, fleshy fruit, and delicious taste that, upon hearing of it, the Queen Mother of the West sent the white ape to steal it for her Peach Banquet.
This last part is a reversal of Sun Wukong stealing the Queen Mother’s peaches in Journey to the West (Xiyouji, 西遊記, 1592).

Astute readers will notice that the tale does not touch on the white ape’s religious title, the “Perfected Man” (Zhenren, 真人). Perfected individuals rank among the highest transcendents of the celestial hierarchy and even rule over lower immortals residing in various earthly paradises (Miura, 2008). This contrasts with the meager, filial son presented in the story. It also contrasts with the white ape’s iconography as an armor-clad martial deity. Perfected individuals are usually portrayed as lofty immortals wearing robes decorated with Daoist symbols (Stevens & Welch, 1998, for example).
I reached out to the Zhenji Temple of Bade District, Taoyuan, Taiwan (Taoyuan Bade Zhenji gong, 桃園八德鎮齊宮), where the White Ape Perfected Man is worshiped as the main deity (zhu shen, 主神) (fig. 9), to make sense of these disparate strands. However, they did not get back to me by the time this article was ready for publication. I’ll make an update when new information becomes available. But until then, I suggest his martial iconography was directly influenced by depictions of the Great Sage Equaling Heaven, whose cult is far more prevalent in Taiwan. This proposed connection to Sun Wukong becomes even more evident when the information below is taken into account.

II. Vernacular Fiction
The White Ape Perfected Man’s religious story can be traced directly to The Battle of Wits between Sun and Pang (Sun Pang douzhi yanyi, 孫龐鬥智演義, 1636; a.k.a. The Former and Latter Annals of the Seven Kingdoms, Qianhou qiguo zhi, 前後七國志), which tells of the great struggle between Sun Bin and his former friend and classmate Pang Juan (龐涓). The two study supernatural military arts under the Immortal Master Ghost Valley (Guigu xianshi, 鬼谷仙師) in his “Water Curtain Cave” (Shuilian dong, 水簾洞) before their fates take separate paths and they become bitter enemies. Chapter four sees the teacher appoint Sun as guardian of an immortal peach tree on the backside of Yunmeng Mountain. But the young disciple is surprised to discover a talking white ape stealing peaches night after night. When asked how it can speak, the primate reveals his aristocratic family has been soaking up immortal qi energy for three generations northwest of the Master’s cave. His ancestor is the Marquis of Baxi (Baxi hou, 巴西侯),  his father the Duke Macaque (Ju gong, 狙公),  and his mother the Princess Mountain Blossom (Shanhua gongzhu, 山花公主).  When asked why he’s stealing peaches (fig. 10), the white ape reveals he’s trying to cure his mother of an illness and that she will die unless the treatment is completed. Taking pity on the filial primate, Sun picks the last peach needed and gives it to the white ape, telling him never to return to the orchard. The grateful son repays the favor by stealing three scrolls of heavenly books (tianshu, 天書) from Master Ghost Valley’s secret hiding place to give to his mother’s savior.
But Sun Bin mistakenly incurs the wrath of heaven not only because he acquires the books before he’s fated to but also because he fails to ritually cleanse himself before reading them. Master Ghost Valley is forced to intervene on his student’s behalf by teaching Sun how to hide from heavenly punishment (da zainan, 大災難, lit: “great tribulation”) by meditating in a cave for 49 days (Wumen xiaoke & Yanshui sanren, 1636).
This novel shares many elements with Journey to the West. Both include:
- Characters surnamed Sun (孫) (Sun Bin VS Sun Wukong) living in a “Water Curtain Cave”. 
- Sun characters studying under an immortal master (Master Ghost Valley VS Master Subodhi). 
- Sun characters being directed to guard trees laden with immortal peaches (one tree on earth VS an entire grove in heaven).
- Supernatural primates stealing the magic peaches for consumption (the white ape VS the Monkey King). 
- Sun characters defying their fate and incurring the wrath of heaven, thereby learning from their masters how to hide from punishment (Sun Bin Vs. Sun Wukong). 
Fig. 10 – A lovely New Years print depicting scenes from the story, including the “White Ape steals peaches” (right) and the “White Ape is filial to mother” (left) (larger version). The right print includes Master Ghost Valley and a young Sun Bin. Print found here.
[The rogue immortal Huaguang (華光)] works to end his mother’s demonic lust for flesh by procuring an immortal peach in chapter 17. He does this by transforming into Sun Wukong and stealing the magic fruit from heaven. The real Monkey King is subsequently accused of his double’s misdeeds, much like the Six-Eared Macaque episode of the original novel. The Jade Emperor threatens to remand him to the Buddha for punishment but is convinced to give Sun a month-long reprieve to find the true culprit.
So we have two magical primate characters (the white ape VS Huaguang-as-Sun Wukong) that steal immortal peaches to help cure their mothers. This association with the rogue immortal might then explain why the statue of the White Ape Perfected Man from figure one has a third eye. Huaguang’s various incarnations are described as having three eyes in Journey to the South (for example) (Yu, n.d.).
Therefore, it seems that these later novels borrowed from Journey to the West, as well as each other. But I will show the theme of a primate stealing fruit actually predates the standard Ming edition of Journey to the West by hundreds of years, suggesting it too borrowed from an earlier source.
III. Taoist Literature
The story of Sun Bin and the white ape actually prefaces the first scroll of the Scripture of the Most High Luminous Mirror of the Six Ren Tallying with Yin (Taishang liuren mingjian fuyin jing, 太上六壬明鑑符陰經) (a.k.a., the Ape Book, Yuanshu, 猿書),  a Northern Song-era work related to the Taoist doctrine of the Three Sovereigns (Steavu, 2019, p. 195). Instead of peaches, the tale just says “fruit” (guo, 菓). But I imagine the produce is something special like immortal peaches as Sun guards them with a weapon. A rough translation follows (I have skipped over some of the more esoteric parts that escape me):
[Master Ghost Valley] saw the fruit had ripened, so he commanded Sun to watch over it. One night a person jumped the wall into the nine gardens and took some of the fruit. But Sun was hiding with a sword and caught the culprit, a white ape. The primate said: “Don’t hurt my body. I share the same age as heaven and earth and have lived as long as the sun and moon. I have mysterious texts (xuanwen, 玄文). Wait for me the next day and I will give them to you”. The white ape then transformed into white light and left. Sun waited the following day. Suddenly, he saw the white ape fly from the northwest. He was given one scroll of mysterious texts. The primate again transformed into white light and headed towards the southeast. Sun then returned to his room to inspect the text. He didn’t know the name but saw that it was divided into three volumes: initial (shang, 上), middle (zhong, 中) and final (xia, 下). He named it after the white ape (Taishang liuren, n.d.).
The story of a magic monkey stealing peaches was already present in the Journey to the West story cycle by the 13th-century, for the “Monkey Pilgrim” (Hou xingzhe, 猴行者), Sun Wukong’s predecessor, admits to raiding the Queen Mother’s orchard when he was still a young immortal (Wivell, 1994, p. 1195). But the preceding Daoist scripture indicates the motif is even older.  In addition, the scripture shows the idea of a character surnamed Sun (Sun Bin) guarding special fruit predates the motif in the standard Ming edition of Journey to the West. It’s not a stretch then to suggest the Most High Luminous Mirror (or related media) influenced the 13th and later 16th-century versions of the story. Therefore, it’s possible the tales of Sun Bin, the white ape, and Sun Wukong have been borrowing from each other for hundreds of years.
This centuries-long association between the magical primates in literature then strengthens my suggestion that the White Ape Perfected Man’s iconography was directly influenced by that of Sun Wukong. Drawing upon a well of preexisting cultural beliefs and imagery likely helped the cult of this relatively recent deity establish itself faster, allowing him to take his place in a rapidly evolving religious landscape where ever newer gods are constantly added to the ranks of their older brethren.
The White Ape Perfected Man is a rare folk Taoist deity associated with revealing heavenly scriptures to the Warring States military strategist Sun Bin (4th-cent.). His statues depict him as a seated, armor-clad primate with a “fist over foot” motif and the long hair and golden fillet of military monks from Chinese opera. This martial iconography conflicts with the deity’s title, “Perfected Man”, a high-ranking immortal usually depicted wearing robes. It also conflicts with his own religious story, which presents him as a meager, filial son who steals immortal peaches to cure his sick mother. I suggested above that his religious imagery was directly influenced by depictions of Sun Wukong as the Great Sage Equaling Heaven. Beyond shockingly similar iconography, both primate deities have a long association in Chinese popular literature. The white ape appears in The Battle of Wits Between Sun and Pang (1636), which shares many similarities with Journey to the West (1592). These include characters surnamed Sun (孫) (Sun Bin VS Sun Wukong) living in a Water Curtain Cave, studying under immortal masters (Ghost Valley VS Subodhi), guarding immortal peaches, and hiding from heavenly punishment. It also includes supernatural primates (the white ape VS the Monkey King) stealing the life-prolonging fruit for consumption. The number of similarities suggests The Battle of Wits borrowed from Journey to the West. The theft of immortal peaches is already present in a 13th-century version of Journey to the West, but this is preceded by a tale appearing in a work from Taoist canon, the Scripture of the Most High Luminous Mirror of the Six Ren Tallying with Yin. It describes the white ape stealing fruit from a garden protected by Sun Bin. It’s possible the Monkey King’s early story cycle was influenced by this scripture (or related media), suggesting the stories of Sun Wukong, Sun Bin, and the white ape have been borrowing from each other for hundreds of years. This centuries-long connection lends support to the martial iconography of Sun Wukong influencing the religious imagery of the White Ape Perfected Man.
I was under the impression that the White Ape Perfected Man is a deity specific to Taiwan (albeit with a mythos connected to China). But Palmer and Siegler (2017) quote a certain Master Hu, a monk of Mt. Hua in Shaanxi province, China, who claims the immortal taught him a system of primate-based martial arts:
I learned [White Ape Through the Back Boxing] spontaneously; it was transmitted to me by the White [Ape] Immortal (Baiyuan zhenren). When I start, he comes down into me, and I do the forms spontaneously. In the future, perhaps I will arrange it into a method in stages that can be taught to others. The White [Ape] Immortal first transmitted the method to humans in the spring and autumn period (770–476 BC), but owing to the poor moral quality of the inheritors of the method, it was lost. Now, it has been transmitted directly to me by the Immortal (pp. 120-121).
The notion of a white ape revealing knowledge matches with what I have described above. Teaching boxing also aligns with the martial iconography. But northern China is so far removed from the available information that I have to question whether or not this a different figure with the same name. I’ve written the authors to see if I can learn more about this Chinese variant.
Also, Master Ghost Valley’s association with the Water Curtain Cave goes back to at least the Northern Song as his Numinous Writ of the Essence of Heaven (Guigu zi tiansui lingwen, 鬼谷子天隨靈文) lists him as the “Master of the Waterfall Cave” (Shuilian dong zhu, 水濂洞主) (Andersen, 2019). In this case, the source uses a different lian (濂) in place of the lian (簾) associated with the caves of the Master (and Sun Bin) in The Battle of Wits between Sun and Pang (1636) and Sun Wukong in Journey to the West (1592). But they both mean the same thing: a waterfall hiding a cave mouth. This might suggest, apart from the guarding and theft of immortal peaches, other elements from Sun Bin’s story cycle were borrowed by that of the Monkey King.
I mentioned in the introduction white face and hair are not always the best indicators that a figure is the White Ape Perfected Man. Take, for example, some depictions of Sun Wukong in glove puppetry (fig. 11).
Yesterday I visited the aforementioned Zhenji Temple of Bade District, Taoyuan, Taiwan (Taoyuan Bade Zhenji gong, 桃園八德鎮齊宮), where the White Ape Perfected Man is venerated. I learned a few things. One, his religious birthday is celebrated on the 27th day of the 5th lunar month (June 25th, 2022), often written as 五月廿七日. Two, his mother, the “Holy Mother of Nine Rivers” (Jiujiang shengmu, 九江聖母), is also worshiped at the temple (her birthday is the 15th day of the 1st lunar month). A temple booklet provided to me tells her story (fig. 12 & 13). I paraphrase the tale below:
Five hundred years before the Spring and Autumn and Warring States Periods, there were three godly brothers named Sun Wuzi (孫武子), Sun Yuanzi (孫圓子), and Sun Huanzi (孫環子). The eldest brother Wuzi and the youngest Huanzi fought for status. But because the latter killed the former with evil magic, Sun Huanzi was sentenced by the Jade Emperor to die on the “Immortal-Beheading Platform” (Zhanxian tai, 斬仙台). The brothers were reborn in the mortal realm five hundred years later during the Warring States period. Sun Wuzi was reborn as Sun Bin in the Yan state, Sun Yuanzi was reborn as (the white ape) Xiaobai (小白) in the Qin state, and Sun Huanzi was reborn as Pang Juan in the Wei State.
The mother of the white ape was the third princess of the Qin state. One day, she became thirsty while touring the imperial garden. But in the absence of tea, she sated her thirst with sweet dew from tree leaves. Three months later, the princess discovered to her surprise that she, an unwed woman, was pregnant. When her father the king learned of this news, he expelled her from the palace. Sometime later, she came by accident to Swallow Lake (Yanzi hu, 燕子湖), a pure, mirror-like body of water surrounded by exotic, fragrant flowers and singing birds and insects. After wandering around this indescribable paradise for sometime, the princess became tired and went to sleep. She dreamed of a golden swallow that told her the child she was carrying was a god reincarnated on earth. It also asked the princess to practice spiritual cultivation beside the lake, promising her that she would one day became an immortal. She realized it was just a dream when she woke up, but she followed through with her training.
Ten days later she gave birth to her son, who was not quite human or demon. His entire body was covered with white hair just like a white ape. The local people claimed that he was a monster, but despite her anger, she raised him patiently. When he was three years old, heaven bestowed on him three divine treasures: an As-You-Will Vajra Staff (Ruyi jingang bang, 如意金剛棒), a golden headband spell (jinquan zhou, 金圈咒), and the steed Red Hare (Chitu ma, 赤兔馬). When the white ape was eight years old, a demon came to threaten the villagers around Swallow Lake. The white ape fought the monster and won, leading the people to believe he was a great celestial immortal (Dalou tianxian, 大羅天仙) come to save the world.
When the white ape was sixteen, his mother’s holy spirit left her body, and the evil Sage Sea Tide (Haichao shengren, 海潮聖人) cast his heavenly treasure around it, thus making her body sick. The Patriarch Reaching Heaven (Tongtian jiaozhu, 通天教主) then appeared to tell the white ape that the only way to cure his mother was to feed her one of the Queen Mother‘s (Wangmu niangniang, 王母娘娘) immortal peaches. After many hardships, he succeeded in his quest and cured her. Upon her recovery, she practiced diligently and eventually achieved immortality.
One day, the immortal princess did divination on her fingers and found that, despite their practice, four other woman around Swallow Lake had yet to achieve the elixir. So, she took them as her servants and continued to guide their practice. After this, she subdued seventeen phoenixes that were the same class of evil spirits as the phoenixes and serpents below the Queen Mother’s gate. Following this, she subdued thirty-six demon dragons as her subordinate generals.
At this time, the god of fire (huoshen, 火神) spread flames everywhere, plunging the world into chaos. The fires killed the surrounding vegetation and created a drought. The immortal princess felt sorry for the people, so she used her powers to defeat the fire god in a great battle. She then transformed nine dragons into nine rivers for the people to drink and to revive the plants and trees. The people were finally able to live in peace. From this point on, they worshiped her as the Holy Mother of Nine Rivers. A temple dedicated to her was built around Swallow Lake in Guangling County, Shanxi Province, China, which is now a first-class protected historic site by the CCP.
It appears that portions of this story were taken from the Qing-era novel Spring and Autumn of Stabbing Swords (Fengjian chunqiu, 鋒劍春秋). The godly Sun brothers, the evil Sage Sea Tide, and even the white ape appear therein.
I’d also like to highlight that the white ape’s staff and headband are modeled on that of Sun Wukong, strengthening my suggestion that the former’s iconography was based on the latter.
1) The idea of a white ape sharing heavenly knowledge goes back centuries. For example, one 4th-century source reveals Zhou Qun (周羣/群, 3rd-cent.) learned the art of divination from a book of bamboo slips given to him by a gibbon-turned-old man in the Min Mountains (Gulik, 1967, p. 50).
2) Sun is appointed the guardian of the immortal peach groves in chapter four. He starts eating the life-prolonging fruit early in his tenure, and his theft is eventually discovered by attendants of the Queen Mother of the West (Wu & Yu, 2012, pp. 160 and 162-163).
3) The Marquis of Baxi (Baxi hou, 巴西侯) is an ape spirit appearing in a story from the Song-era Extensive Records of the Taiping Era (Taiping guangji, 太平廣記, 978). A retired official from Sichuan is invited to an eerie, drunken party by the Marquis, only to wake up the next morning to find his host was a gibbon and all of the other guests were also animal spirits (Gulik, 1967, pp. 67 and 68-69).
4) The only Duke Macaque (Ju gong, 狙公) that I’m aware of is a human keeper of monkeys from a parable on freedom appearing in The Collected Works of Bowen (Chengyi Bowen ji, 诚意伯文集, 14th-cent.). I’m not sure if the novel is claiming the ape has a human father, or if it’s just a vague reference to a character from Chinese literature with a connection to primates.
5) I can’t find any information on this character. But given the ancestor and father, I’m sure the mother is associated with apes or monkeys in some way.
6) Wukong becomes king of the monkeys in chapter one by discovering a cave, the Water Curtain Cave (Shuilian dong, 水簾洞), behind a waterfall. His people soon after take residence inside (Wu & Yu, 2012, pp. 104-106).
7) See my article on Master Subodhi’s curriculum.
8) See note #2.
9) Monkey learns the 72 transformations in order to escape heavenly punishments of lightning, fire, and wind sent to kill him for defying his fate by attaining immortality.
10) Steavu (2019) calls it the “Monkey book” (p. 195), but a gibbon is an ape, so I have adjusted the translation accordingly.
11) I suggest in this article that the supernatural ape stealing peaches motif could be a mixture of a Sinicized version of the Great Monkey jataka tale, in which the Buddha’s reincarnation as a monkey king leads his people to raid an imperial fruit garden, and the theft of immortal peaches by the planet Jupiter (Sui, 歲), who is subsequently exiled to reincarnate as the Han-era jester Dongfang Shuo (東方朔).
