A twitter user asked me in late 2024 where Zhu Bajie (豬八戒; fig. 1) learned his “36 transformations” (sanshiliu ban bianhua, 三十六般變化). I told them that chapters 19 and 85 of Journey to the West (Xiyouji, 西遊記; “JTTW” hereafter) contain biographical poems, one of which explains his internal alchemy (neidan, 内丹) training under an immortal and ascension to godhood. I suggested that his past human life learned the magic changes during this time, but after answering the question, it dawned on me that many people may not be aware of these verses. I have, therefore, decided to post and analyze said poems for the benefit of my readers.

This is the second of three articles where I will present info about the disciples’ lives prior to the main events of JTTW. My next article will follow with Sha Wujing‘s (沙悟净) poem. Click here to read the first post about the White Dragon Horse (Bai longma, 白龍馬). These are meant to compliment my previous essay about Sun Wukong (孫悟空).

(On a related note, see here for the oldest known depictions of Zhu Bajie. They come from 14th-century Korea!)

1. The Poems

The novel actually presents two contradictory verses on the origins of our beloved pig-monster. One (ch. 19) portrays him as a human-turned-immortal commander of heavenly forces, while the other (ch. 85) alludes to him being a powerful hog-spirit given celestial rank.

1.1. Chapter 19

This poem is chock-full of internal alchemical jargon, so I’m placing explanatory notes just below the blockquote to save readers from having to scroll to the very bottom of the article every time a new concept is mentioned.

My mind was dim since the time of youth;
Always I loved my indolence and sloth.
Neither nursing nature nor seeking the Real,
I passed my days deluded and confused.
I met a true immortal suddenly
Who sat and spoke to me of cold and heat. [A]
‘Repent,’ he said, ‘and cease your worldly way:
From taking life accrues a boundless curse.
One day when the Great Limit ends your lot,
For eight woes and three ways you’ll grieve too late!’ 
I listened and turned my will to mend my ways:
I heard, repented, and sought the wondrous rune.
By fate my teacher he became at once,
Pointing to the Heavenly and Earthly Passes. [B]
Taught to forge the Great Pill Nine Times Reversed, [C]
I worked without pause through day and night
To reach Mud-Pill Palace topping my skull [D]
And Jetting-Spring Points on soles of my feet. [E]
With kidney brine flooding the Floral Pool, [F]
My Cinnabar Field was thus warmly nursed. [G]
Baby and Fair Girl mated as yin and yang; [H]
Lead and mercury mixed as sun and moon. [I]
In concord Li-dragon and Kan-tiger used, [J]
The spirit turtle sucked dry the gold crow’s blood. [K]
‘Three flowers joined on top,’ the root reclaimed [L];
‘Five breaths faced their source’ and all freely flowed. [M]
My merit done, I ascended on high,
Met by pairs of immortals from the sky.
Radiant pink clouds arose beneath my feet;
With light, sound frame I faced the Golden Arch.
The Jade Emperor gave a banquet for gods
Who sat in rows according to their ranks.
Made a marshal of the Celestial Stream,
I took command of both sailors and ships.
Because Queen Mother gave the Peaches Feast
When she met her guests at the Jasper Pool
My mind turned hazy for I got dead drunk,
A shameless rowdy reeling left and right.
Boldly I barged into Vast Cold Palace
Where the charming fairy received me in.
When I saw her face that would snare one’s soul,
My carnal itch of old could not be stopped!
Without regard for manners or for rank,
I grabbed Miss Chang’e asking her to bed.
For three or four times she rejected me:
Hiding east and west, she was sore annoyed.
My passion sky-high I roared like thunder,
Almost toppling the arch of Heaven’s gate.
Inspector General told the Emperor Jade;
I was destined that day to meet my fate.
The Vast Cold completely enclosed airtight
Left me no way to run or to escape.
Then I was caught by the various gods,
Undaunted still, for wine was in my heart.
Bound and taken to see the Emperor Jade,
By law I should have been condemned to death.
It was Venus the Gold Star, Mr. Li,
Who left the ranks and knelt to beg for me.
My punishment changed to two thousand blows,
My flesh was torn; my bones did almost crack.
Alive! I was banished from Heaven’s gate
To make my home beneath the Fuling Mount.
An errant womb’s my sinful destination: Stiff-Bristle Hog’s my worldly appellation!” (Wu & Yu, 2012, vol. 1, pp. 378-379).

自小生來心性拙，貪閑愛懶無休歇。
不曾養性與修真，混沌迷心熬日月。
忽然閑裡遇真仙，就把寒溫坐下說。
勸我回心莫墮凡，傷生造下無邊孽。
有朝大限命終時，八難三途悔不喋。
聽言意轉要修行，聞語心回求妙訣。
有緣立地拜為師，指示天關並地[關]闕。
得傳九轉大還丹，工夫晝夜無時輟。
上至頂門泥丸宮，下至腳板湧泉穴。
周流腎水入華池，丹田補得溫溫熱。
嬰兒姹女配陰陽，鉛汞相投分日月。
離龍坎虎用調和，靈龜吸盡金烏血。
三花聚頂得歸根，五氣朝元通透徹。
功圓行滿卻飛昇，天仙對對來迎接。
朗然足下彩雲生，身輕體健朝金闕。
玉皇設宴會群仙，各分品級排班列。
敕封元帥管天河，總督水兵稱憲節。
只因王母會蟠桃，開宴瑤池邀眾客。
那時酒醉意昏沉，東倒西歪亂撒潑。
逞雄撞入廣寒宮，風流仙子來相接。
見他容貌挾人魂，舊日凡心難得滅。
全無上下失尊卑，扯住嫦娥要陪歇。
再三再四不依從，東躲西藏心不悅。
色膽如天叫似雷，險些震倒天關闕。
糾察靈官奏玉皇，那日吾當命運拙。
廣寒圍困不通風，進退無門難得脫。
卻被諸神拿住我，酒在心頭還不怯。
押赴靈霄見玉皇，依律問成該處決。
多虧太白李金星，出班俯顖親言說。
改刑重責二千鎚，肉綻皮開骨將折。
放生遭貶出天關，福陵山下圖家業。
我因有罪錯投胎，俗名喚做豬剛鬣。(source)

Footnotes:

A) “[C]old and heat,” (riyue, 日月; lit: “sun and moon”) refers to respective yang and yin energies (Pregadio, 2025p; see also Wu & Yu, 2012, vol. 1, p. 527 n. 2).

B) The original Chinese, “天關並地闕” (tianguan bing dique, or “heavenly passes and earthly watchtowers(?)”), is a likely typo for “天關並地關” (tianguan bing diguan, or “heavenly and earthly passes”). These respectively refer to the head and feet (Pregadio, 2025d, 2025s). I’ve therefore altered Yu’s (Wu & Yu, 2012) translation.

C) The “Great Pill [i.e. Elixir] Nine Times Reversed” (jiuzhuan da huandan, 九轉大還丹) was originally an external alchemical process where a concoction of toxic elements was purified over successive firings in a crucible to create a drug of immortality (see section 3.1. of this article). However, the term was coopted by later proponents of internal alchemy, who associated the ingestion and circulation of immortality-bestowing cosmic energies within pathways between bodily organs with a complex five phases-influenced numerology (Pregadio, 2025b, 2025n). Needham (1954, as cited in Wu & Yu, 2012) adds that it refers “to a chhi [qi, pneumatic vitality, breath] or substance generated by techniques purposefully within the human body which would bring about a reversion of the tissues from an ageing state to an infantile state” (vo. 1, p. 527 n. 4).

D) The “Mud-Pill Palace” (niwan gong, 泥丸宮) is a name for the upper cinnabar field in the head (Pregadio, 2025m; Wu & Yu, 2012, vol. 1, p. 528 n. 6).

E) The “Jetting-Spring Points” (yongquan xue, 湧泉穴) are pressure points on the bottom of the feet (Wu & Yu, 2012, vol. 1, p. 528 n. 7).

F) Yu (Wu & Yu, 2012) explains that spiritual energies contained in the kidneys (which are associated with the water element) can be directed to different parts of the practitioner’s body, including a spot under the tongue, the “Floral pool” (huachi, 華池) (vol. 1, p. 528 n. 8; see also Pregadio, 2025r). While this is no doubt the correct answer, it’s important to note that internal alchemy also uses the term Floral pool to refer to true yang energy inside yin (Pregadio, 2025h). The corresponding term is “spirit water” (shenshui, 神水), which denotes true yin energy inside yang—think of the white and black dots inside of the Taiji symbol (Pregadio, 2025h). Therefore, the poem’s original Chinese “腎水入華池” (shenshui ru huachi, or “kidney brine flooding the floral pool”) could also be a reference to the similarly-sounding phrase “神水入華池” (shenshui ru huachi, or “spirit water flooding the floral pool), or the mixture of yang and yin, respectively.

G) The “Cinnabar Field” (dantian, 丹田) is one of three spiritual centers in the body, which is located between 1.3 to 3.6 Chinese inches (cun, 寸; 1 = 1.25 in/3.18 cm) below (or behind) the belly button. The Cinnabar Field is believed to store cosmic/bodily energies, that when circulated and refined, produce an immortal alchemical embryo—i.e. a fledgling immortal spirit avatar (Pregadio, 2025c; see also Wu & Yu, 2012, vol. 1, p. 528 n. 9). And “warmly nursed” (bu de wenwen’re, 補得溫溫熱) may refer to “nourishing warmly” (wenyang, 溫養), or the process of “gestati[ng] the alchemical embryo” (Pregadio, 2025t).

H) The “Baby and Fair Girl” (ying’er chanu, 嬰兒姹女) are anthropomorphic personas of yang and yin energy, respectively (Pregadio, 2025a, 2025w; see also Wu & Yu, 2012, vol. 1, p. 528 n. 10).

I) The elemental and celestial imagery of “lead and mercury” (qian gong/hong, 鉛汞) and “sun and moon” (riyue, 日月) refer to yang and yin energies, respectively (Pregadio, 2025g, 2025o, 2025p).

J) The third eight trigram figure, Li (離/☲), is associated with dragons (long, 龍), and both symbolize yang energy. The sixth figure, Kan (坎/☵), is associated with tigers (hu, 虎), and both symbolize yin energy (fig. 2) (Pregadio, 2025j, 2025k, 2025l; see also Wu & Yu, 2012, vol. 1, p. 529 n. 11).

K) Yu (Wu & Yu, 2012) suggests that “turtle” (gui, 龜) “may be another name for the dark liquid of the kidneys” (vol. 1, p. 529 n. 12). He continues, “[T]he gold crow indicates the sun or the heart. The line refers to the union of yin and yang through the absorption of yang energy by yin” (Wu & Yu, 2012, vol. 1, p. 529 n. 12). While I agree that this refers to the mixing of said energies, it’s important to note, however, that turtles are usually paired with “snakes” (she, 蛇), both being anthropomorphic symbols of jing-essence and qi-breath (精氣), respectively (Pregadio, 2025f). Additionally, the “gold crow” (jinwu, 金烏), an anthropomorphic symbol of true yin inside yang energy, is normally paired with the “jade rabbit” (yutu, 玉兔), an anthropomorphic symbol of true yang inside yin (Pregadio, 2025i, 2025y). Similarly, “blood” (xue, 血) represents true yin inside of yang (Pregadio, 2025v).

L) The “Three flowers” (sanhua, 三花) is another name for jing-essence, qi-breath, and shen-spirit (精氣神), three important bio-spiritual substances/energies. These must be “joined on top” (juding, 聚頂), or concentrated in the head (the upper cinnabar field) during the internal alchemical process (Wu & Yu, 2012, vol. 1, p. 529 n. 13; see also Pregadio, 2025q). This leads to the “root [being] reclaimed” (guigen, 歸根), which refers to “[g]oing back to the root and returning to the mandate” (guigen fuming, 歸根復命), or achieving immortality (Pregadio, 2025e).

M) Yu (Wu & Yu, 2012) explains, “Five breaths … wuqi chaoyuan 五氣朝元, refers to the pneumatic vitality, qi, of the five viscera (heart, liver, spleen, lungs, and kidneys) in harmonious balance” (Wu & Yu, 2012, vol. 1, p. 529 n. 14). A related view is that said viscera are synced with bio-spiritual substances or mental concepts—ie. hun/liver, jing-essence/kidneys, spirit/heart, po/lungs, intention/spleen—when a practitioner has learned to quiet their senses and still their body (Pregadio, 2025u).

1.2. Explanation

Zhu was originally a lazy, aimless man, but he encountered a celestial who told him to mend his ways, or else he would be reborn in the lower three Buddhist realms of hell, hungry ghosts, or animals, making it impossible for him to hear the Buddha’s teachings (an example of the novel’s syncretic unity). Upon repenting, he studied under the immortal, learning the art of internal alchemy, which involved absorbing and circulating vital energies around his body. Once he had attained transcendence, he rose on clouds to be escorted by other celestials into the heavenly realm, where he was appointed marshal of the heavenly navy, which sailed the cosmic river of the Milky Way Galaxy.

But his great achievement was tainted when he got drunk at the Queen Mother’s peach banquet and, being aroused by Chang’e’s dazzling beauty (fig. 3), chased her to the moon palace. He propositioned the goddess for sex several times, but her refusals sent him into a powerful rage. The protector deity Wang Lingguan reported this to the Jade Emperor, who had the moon palace surrounded by heavenly soldiers. The Marshal was soon captured and sentenced to death, but the planet Venus asked for lenience, leading to Zhu’s past life being beaten 2,000 times and banished from the heavenly realm. His divine spirit sought reincarnation in the mortal realm below, but an accident of fate led to his rebirth as a pig-spirit. He later took the name “Stiff-Bristles Hog” (Zhu Ganglie, 豬剛鬣) based on his porcine appearance.

Fig. 3 – A Taiwanese stamp reading, “Drunkenly playing Chang’e” (Zuixi Change, 醉戲嫦娥) (larger version). It’s likely meant to serve as a visual reminder of Zhu’s early story arc involving the events leading to his banishment from heaven and rebirth as a hog-spirit.

1.3. Chapter 85

With huge mouth and fangs I’ve great magic might.
Emperor Jade made me Marshal Heavenly Reeds.
The boss of Heaven’s eighty-thousand marines,
Comforts and joys I had in the halls of light.
Because I mocked a palace maiden when I was drunk
And flaunted my strength at a wrongful hour
One shove of my snout toppled the Dipper–Ox Palace;
Queen Mother’s divine herbs I then devoured
Emperor Jade pounded me two thousand times
And banished me from the Three Heavens realm.
Though told to nourish my primal spirit,
I became again a monster down below.
About to marry at the Village Gao, I met Brother Sun—’twas my wretched fate!
Quite defeated by his golden-hooped rod,
I had to bow and take the Buddhist vow:
A coolie who bears luggage and leads the horse,
Who owes, in former life, the Tang Monk a debt!
This iron-legged Heavenly Reed‘s name is Zhu;
And my religious name is Zhu Eight Rules” (based on Wu & Yu, 2012, vol. 4, pp. 149-150).

巨口獠牙神力大，玉皇陞我天蓬帥。
掌管天河八萬兵，天宮快樂多自在。
只因酒醉戲宮娥，那時就把英雄賣。
一嘴拱倒斗牛宮，吃了王母靈芝菜。
玉皇親打二千鎚，把吾貶下三天界。
教吾立志養元神，下方卻又為妖怪。
正在高莊喜結親，命低撞著孫兄在。
金箍棒下受他降，低頭才把沙門拜。
背馬挑包做夯工，前生少了唐僧債。
鐵腳天蓬本姓豬，法名喚作豬八戒。(source)

1.4. Explanation

He was originally a pig-spirit with sharp tusks and powerful magic (fig. 4) who was appointed Marshal Tianpeng, commander of the 80,000-strong celestial navy. He enjoyed his new life among the godly ranks but later got drunk (at the Queen Mother’s banquet) and performed a number of forbidden deeds: mistreating a moon goddess, knocking over the Dipper-Ox Palace, and eating the Queen mother’s magic mushrooms. This resulted in a punishment of 2,000 strokes and banishment from heaven, with the added instruction to cultivate his spirit while on earth. But he once again became a monster, and at some point,  he took a wife in Gao Village. He was subsequently defeated by Monkey and forced to take the Buddhist vows, serving as Tripitaka’s disciple and luggage handler. His discipleship may have been the karmic result of a good deed that his master performed for him in a past life.

2. Which is True?

Both poems provide certain information that is consistent with internal narrative details, such as:

• Zhu originally serving as Marshal Heavenly Reed (Tianpeng yuanshuai, 天蓬元帥; lit: “Marshal of Heavenly Mugwort“), commander of the 80,000 soldiers of the celestial navy (and a historical deity) (fig. 5)
• Getting drunk at the peach festival and harassing a moon goddess
• Being beaten 2,000 times as punishment and exiled to the mortal world
• Mistakenly being reborn as Stiff-Bristles Hog, a bloodthirsty pig-monster in Fuling Mountain (Fuling shan, 福陵山)
• Eventually taking a wife in Gao Village (Gao zhuang, 高莊)
• Being defeated by Sun Wukong
• Becoming Zhu Bajie, a Buddhist disciple of Tripitaka
• Acting as a coolie carrying the luggage

But the real question is: was Zhu originally human or a pig-spirit? I think the first poem is likely true (within the narrative) given the amount of detail that he provides about the alchemical processes that eventually led to his immortality and ascension to godhood. The second poem is cursory in comparison and seems like something that was made up on the spot to embellish his might—perhaps influenced by stories of Sun Wukong’s past havoc in heaven—or monstrous pedigree in the face of a demonic opponent (refer to the events in chapter 85). One detail pointing to this is his claim of knocking over the “Dipper-Ox Palace” (Douniu gong, 斗牛宮), which references the stars of the Southern Dipper and Ox mansions (Stephenson, 2008, p. 517). He’s therefore asserting that he can collapse entire constellations. That’s definitely nonsense as Zhu is often overpowered and defeated in battle, even by groups of little fiends (Wu & Yu, 2012, vol. 2, pp. 102-103, for example).

3. Additional Info

The poems actually leave out several details about Zhu’s past and current lives.

1. The Chang’e (嫦娥) mentioned above is not the singular goddess but one of many such named divine maidens in the entourage of the “Star Lord of Supreme Yin” (Taiyin xingjun, 太陰星君), the aged devi of the moon. [1]
2. He mauled his sow mother and piglet siblings to death sometime after his mistaken rebirth in Fuling Mountain (Wu & Yu, 2012, vol. 1, p. 212).
3. His first wife, “Second Elder Sister Mao” (Mao erjie, 夘二姐), [2] a likely rabbit spirit, [3] was the original owner of his Cloudy Paths Cave (Yunzhan dong, 雲棧洞) (Wu & Yu, 2012, vol. 1, p. 212). But sadly, she died less than a year after their marriage (Wu & Yu, 2012, vol. 1, p. 212). Their tragic love story would be good fodder for fanfiction.
4. He was invited by the Crow’s Nest Chan Master (Wuchao chanshi, 烏巢禪師), a Buddhist sage, to practice austerities, but he passed on the opportunity.
5. Years prior to being called Zhu Bajie, he submitted to Buddhism at the behest of the bodhisattva Guanyin and was given the religious name “Zhu Wuneng” (豬悟能, “Pig Who Awakens to Power”) (Wu & Yu, 2012, vol. 1, p. 213).
6. Sometime after adopting a vegetarian diet, [4] he magically transformed into a “stout, swarthy [human] fellow” (hei pang han, 黑胖漢) in order to fraudulently arrange a marriage with his second wife, “Green Orchid” (Cui’lan, 翠蘭), a maiden from Gao Village in Tibet (Wusizang, 烏斯藏) (Wu & Yu, 2012, vol. 1, p. 372). [5]
7. The Gao family grew rich from his supernatural labors in the field (Wu & Yu, 2012, vol. 1, pp. 375 and 381).
8. But he was abusive to his wife, locking her inside a back building and not allowing her to see her family for half a year (Wu & Yu, 2012, vol. 1, p. 372).
9. Monkey tricked Zhu by magically taking his wife’s form and hiding in a dark room (fig. 6), [6] but he later overpowered the hog-spirit in combat (Wu & Yu, 2012, vol. 1, p. 380). Zhu eventually submitted when he learned Sun was escorting the scripture pilgrim to India (Wu & Yu, 2012, vol. 1, p. 384).

Lastly, I would like to suggest that the immortal teacher of Zhu’s past life also taught him divine military arts—like Master Ghost Valley taught Sun Bin in vernacular fiction—because why else would a random person be given command of the entire heavenly navy? I headcanon that he was once a brilliant military strategist and commander, but his mistaken reincarnation as a hog made him very dim and lazy.

Update: 03-04-25

Friend of the blog NingadudeXx has drawn a picture of Zhu Bajie as his past life, Marshal Tianpeng (fig. 7), based on the god’s historical iconography (refer back to fig. 5).

Update: 04-09-25

I forgot to mention that Zhu has some medical knowledge. In chapter 41, for example, he performs life-saving massage to resuscitate a dead Sun Wukong:

With a chuckle, Eight Rules [Zhu Bajie] said, “Brother, stop crying. This ape is pretending to be dead, just to scare us. Feel him a little and see if there’s any warmth left in his breast.” “The whole body has turned cold,” said Sha Monk [Sha Wujing]. “Even if there were a little warmth left, how could you revive him?” Eight Rules said, “If he is capable of seventy-two transformations, he has seventy-two lives. Listen, you stretch out his legs while I take care of him.” Sha Monk indeed straightened Pilgrim’s legs while Eight Rules lifted his head and straightened his upper torso. They then pushed his legs up and folded them around the knees before raising him into a sitting position. Rubbing his hands together until they were warm, Eight Rules covered Pilgrim’s seven apertures and began to apply a Chan method [anmo chanfa, 按摩禪法] of massage on him (emphasis added). The cold water, you see, had had such a traumatic effect on Pilgrim that his breath was caught in his cinnabar field and he could not utter a sound. He was lucky, therefore, to have all that rubbing, squeezing, and kneading by Eight Rules, for in a moment his breath went through the three passes, invaded the bright hall, and burst through his apertures. and burst through his apertures. “O Master,” he [Monkey] began to say (Wu & Yu, 2012, vol. 2, p. 232).

八戒笑道：「兄弟莫哭。這猴子佯推死，嚇我們哩。你摸他摸，胸前還有一點熱氣沒有？」沙僧道：「渾身都冷了，就有一點兒熱氣，怎的就得回生？」八戒道：「他有七十二般變化，就有七十二條性命。你扯著腳，等我擺佈他。」真個那沙僧扯著腳，八戒扶著頭，把他拽個直，推上腳來，盤膝坐定。八戒將兩手搓熱，仵住他的七竅，使一個按摩禪法。原來那行者被冷水逼了，氣阻丹田，不能出聲。卻幸得八戒按摸揉擦，須臾間，氣透三關，轉明堂，沖開孔竅，叫了一聲：「師父啊！」

Also, in chapter 69, he argues with Wukong about the attributes and usages of a medicinal ingredient:

“The flavour of badou [巴豆],” said Eight Rules, “is slightly acrid; its nature is hot and poisonous. Able to pare down the hard and the accumulated, it will therefore sweep out the submerged chills of one’s internal cavities. Able to bore through clottings and impediments, it will therefore facilitate the paths of water and grain. This is a warrior who can break down doors and passes, and it should be used lightly” (Wu & Yu, 2012, vol. 3, p. 274).

八戒道：「巴豆味辛，性熱有毒。削堅積，蕩肺腑之沉寒；通閉塞，利水穀之道路。乃斬關奪門之將，不可輕用。」

This might suggest that Bajie also learned these skills from his immortal master.

Endnotes:

1) Chapter 95 explains that the seemingly singular goddess Chang’e is actually a collective, and also that one of them was the maiden that Zhu’s former life had harassed in the past:

As they stared into the sky, they heard the Great Sage Sun crying out in a loud voice: “Your Majesty of India, please ask your queen and concubines to come out and look. Beneath this treasure canopy is the Star Lord of Supreme Yin of the Moon Palace, and the immortal sisters on both sides of her* are the Chang’e goddesses inside the moon (emphasis added). This little jade hare is the false princess of your household; she has now revealed her true form.”

The king hurriedly assembled the queen, his concubines, the palace maidens, and gaily-attired girls to bow to the sky and worship. He himself and the Tang Monk also expressed their thanks toward the sky by bowing low. All the households in the city also set up incense tables and kowtowed, chanting the name of Buddha.

As they looked up into the air, Zhu Eight Rules was moved to lust. Unable to contain himself, he leaped into the air and embraced a rainbow-skirted immortal, crying, “Sister, you and I are old acquaintances! Let’s go play!” (emphasis added) (based on Wu & Yu, 2012, vol. 4, p. 303).

眾擡頭看處，又聞得孫大聖厲聲高叫道：「天竺陛下，請出你那皇后、嬪妃看者：這寶幢下乃月宮太陰星君，兩邊的仙妹是月裡嫦娥。這個玉兔兒卻是你家的假公主，今現真相也。」那國王急召皇后、嬪妃與宮娥、綵女等眾朝天禮拜，他和唐僧及多官亦俱望空拜謝。滿城中各家各戶，也無一人不設香案，叩頭念佛。正此觀看處，豬八戒動了慾心，忍不住，跳在空中，把霓裳仙子抱住道：「姐姐，我與你是舊相識，我和你耍子兒去也。」

* Yu (Wu & Yu, 2012) calls the Star Lord of Supreme Yin “him” in his original translation (vol. 4, p. 303), but the deity has been portrayed as a woman for centuries. See, for instance, her depiction (2nd from the top left) in the Ink Treasures of Wu Daozi (Daozi mobao, 道子墨寶, 13th-century).

2) Yu (Wu & Yu, 2012) translates her name as “Second Elder Sister Egg” (Luan erjie, 卵二姐)” (vol. 1, p. 212). But this is based on a transcription error—i.e. 夘 (Mao; original edition) vs 卵 (Luan; modern edition).

3) The relationship of Zhu and Second Elder Sister Mao references the synergy between the elemental and animal aspects of the 12 earthly branches—i.e. Mao (夘; yin wood/rabbit) and Hai (亥; yang wood/pig) complete each other.

4) His vegetarian diet is mentioned in chapters 18 and 19 (Wu & Yu, 2012, vol. 1, pp. 372, 384, and 386).

5) Yu (Wu & Yu, 2012) translates “烏斯藏” (Wusizang), the location of Gao village, as the “Kingdom of Qoco” (Wu & Yu, 2012, vol. 1, p. 369). However, this phrase actually refers to Dbus-gtsang, or Tibet (Zhang, 2023, pp. 32-33; Wilkinson, 2000, p. 728).

6) I’ve previously suggested that this episode was influenced by a scene from chapter five of the Water Margin (Shuihu zhuan, 水滸傳, c. 1400). Both feature:

• Young, beautiful daughters in unwanted relationships (Green Orchid vs the unnamed maiden).
• Elderly fathers worried for their child (Mr. Gao vs Mr. Liu).
• Evil spirit-turned-inhumanly strong, hot-tempered, heavy metal staff-wielding martial monks who come to their aid (Sun Wukong vs Lu Zhishen).
• The monk takes the place of the woman in a darkened room.
• The villain is beaten (Zhu Bajie vs Zhou Tong) (Wu & Yu, 2012, vol. 1, pp. 374-377; Shi & Luo, 1993/2021, pp. 109-113).
