Zhāng Guǒlǎo (張果老) is the eldest and most eccentric of the Eight Immortals (八仙 Bā Xiān). A Daoist hermit and fāngshì (方士, occultist-alchemist) who lived on Zhōngtiáo Mountain (中條山) in Héngzhōu during the Táng dynasty, he claimed to be several hundred years old and to have served as a minister under the legendary Emperor Yáo (尧) in a previous life — placing his origins over three thousand years in the past. He is famous for riding a magical white donkey backwards, for his fish drum, and for his role as a symbol of longevity and the granting of offspring. The epithet Lǎo (老, "old") appended to his name is both honorific and descriptive.

Historical Basis

Zhāng Guǒlǎo is one of only three Eight Immortals (alongside Zhōnglí Quán and Lǚ Dòngbīn) who appear in official historical records as genuine figures. His existence is documented in the New Book of Tang (新唐书 Xīn Táng Shū) under the section on occult arts. He lived as a hermit in the Zhōngtiáo Mountains of southeastern Shānxī Province, wandering between the Fén River and Qín territories. By the time of Empress Wǔ Zétiān (武则天, r. 690–705 CE), he was already famous and claimed to be hundreds of years old.

Both Emperor Tàizōng and Emperor Gāozōng invited Zhāng to the imperial court, but he consistently declined. When Empress Wǔ finally persuaded him to come, he feigned death on the journey — his body immediately began decomposing in the heat. The envoys returned empty-handed. Shortly afterward, travelers in the mountains spotted him alive and well.

At the Court of Emperor Xuánzōng

In 735 CE, Emperor Xuánzōng (玄宗, r. 712–756 CE) succeeded in bringing Zhāng Guǒlǎo to the court at Luòyáng, where the immortal performed various feats of magic. The emperor appointed him chief of the Imperial Academy with the title "Master of Profound Comprehension" (通玄先生 Tōngxuán Xiānshēng).

During this visit, the Daoist necromancer Yè Fǎshàn (叶法善) was asked to reveal Zhāng Guǒlǎo's true identity. Yè replied that he knew, but warned that if he spoke, he would immediately fall dead — and could only be revived if the emperor went barefoot and bareheaded to beg Zhāng's forgiveness. The emperor promised.

Yè then revealed: "Zhāng Guǒlǎo is a white spiritual bat that came out of primeval chaos." With those words, Yè collapsed and died on the spot. The emperor kept his promise, approached Zhāng barefoot, and begged his pardon. Zhāng sprinkled water on Yè's face, and the necromancer returned to life.

Emperor Xuánzōng offered Zhāng the hand of Princess Yùzhēn (玉真) in marriage. Zhāng politely declined, and soon returned to his mountain hermitage.

The Magical Donkey

Zhāng Guǒlǎo's most distinctive attribute is his white donkey (or mule), an animal as extraordinary as its master. The donkey could travel a thousand lǐ (里, approximately 500 kilometers) in a single day. When the journey was finished, Zhāng would fold the donkey up like a piece of paper and tuck it into his pocket or a small box. When he needed to ride again, he would pour water from his mouth onto the folded paper, and the donkey would instantly resume its full living form.

His habit of riding the donkey backwards — facing the animal's tail rather than its head — became one of the most recognizable images in Chinese art and folklore. Various explanations are given for this eccentricity: that he considered it more polite to face people as he passed rather than turning his back to them; that it represented his rejection of conventional perspectives; or that it symbolized the Daoist principle of reversal — looking backward to the origin rather than forward into the illusion of progress.

The Fish Drum

Zhāng Guǒlǎo carries a bamboo tube-drum called a Yúgǔ (鱼鼓, fish drum), made from a bamboo cylinder with one end covered in prepared fish or snake skin, struck with two iron rods or mallets. This instrument, associated with Daoist mendicant wanderers, could allegedly predict fate and invoke rain. It also connects him to the tradition of Dàoqíng (道情), a form of narrative ballad singing that blends spoken recitation with melody, of which he is considered a patron.

Iconography

In art, Zhāng Guǒlǎo appears as a white-haired, white-bearded old man — the very image of extreme old age — seated backwards on his donkey, often carrying his fish drum. He sometimes holds a phoenix feather or a peach of immortality. His appearance emphasizes both his antiquity and his humor — he is depicted with a gentle, knowing expression, often appearing amused by the world around him.

His magical vessel is the fish drum.

Because he represents old age and longevity, his image is traditionally placed in the homes of elderly persons in Daoist Fēngshuǐ (风水) practice to promote long life and a peaceful death. His picture adorning a nuptial chamber — riding his donkey and offering a child to a newly married couple — reflects his role as a patron of fertility and the granting of male offspring.

The Bat and Primordial Chaos

The revelation by Yè Fǎshàn that Zhāng Guǒlǎo was originally a white bat from primordial chaos places him in a unique cosmological position among the Eight Immortals. The bat (蝠 Fú) is a symbol of good fortune in Chinese culture — the character is homophonous with 福 (Fú, blessing or good fortune). A being that emerged from the original undifferentiated chaos (混沌 Hùndùn), transformed through aeons into human form, and attained immortality represents the complete arc of Daoist cosmological possibility — from Wújí (无极) through manifestation to transcendence.

Daoist Teaching

Zhāng Guǒlǎo embodies the Daoist values of simplicity, eccentricity, and the refusal of worldly power. He repeatedly declined imperial invitations, feigned death to avoid court obligations, and ultimately rejected marriage to a princess. His backwards riding, his fish drum, and his paper donkey all carry the flavor of Daoist absurdism — a tradition that uses humor and strangeness to point beyond conventional thinking toward the freedom of the Dao.
