💡 Introduction:
When people enter a temple to pay their respects, the first figure they usually see is the smiling Budai Monk. But if you stand in an empty hall and stare at him for thirty seconds, does that smile begin to feel a little too perfect, a little too uncanny? Behind this most familiar “auspicious symbol” there may be a hidden legend erased by official history, and at its core, a deeply unsettling form of Chinese-style Cthulhu horror.

01 Don’t Stare at His Sack
In the Jiangsu-Zhejiang region, there has long been a faintly mysterious saying in popular religion: “You may worship the Budai Monk, but do not stare at his sack, and do not ask what is inside it. It is inauspicious.”
It sounds like nothing more than old-fashioned superstition. But if you have ever stood in an empty Buddhist hall and fixed your eyes on a statue of Budai for more than thirty seconds without looking away, you may have felt an unease that is difficult to name.
No matter where you stand in the hall, it seems that he is looking at you.
His belly is absurdly large, as if it could swallow the whole world.
And that sack, always slung behind him, what exactly does it contain?
We are told from childhood that Budai is an incarnation of Maitreya, a symbol of generosity, good fortune, and the famous ideal of “a belly broad enough to hold all things, a smile ever open.” But in fact, he originally had nothing to do with Maitreya at all.
As early as the Tang, even in the age of Wu Zetian, devotion to Maitreya was already flourishing, and the images of Maitreya from that period were all solemn and majestic. Budai, by contrast, first appears in the era of the Five Dynasties and Ten Kingdoms, in the Wu-Yue kingdom of what is now eastern Zhejiang. The historical record says only that he was a wandering monk, “unrestrained in form and strange beyond ordinary men.”
It was Song-dynasty Chan monks who forcefully bound Budai to Maitreya. In order to promote the faith, official religion deliberately softened the eerie qualities of this “uncanny monk” and repackaged him as a benign emblem of good fortune. Yet in the oral traditions of eastern Zhejiang, the disturbing details never disappeared: his sack swallowing things whole, and eyes growing across his back.
02 The Eyes on His Back and “Chinese Cthulhu”
The legend of Budai’s back covered in eyes exists in several versions from different periods.
The earliest, in the Southern Song text Fozu Tongji, says that he had a single “heavenly eye” on his back. By the Yuan, in Biography of the Great Master Budai, it had become four eyes splitting open across his back, flashing with light. In a later legend from Hangzhou’s Feilai Peak, a curious boy reaches out to touch Budai’s sack. The sack opens, and inside there are nothing but eyes. The boy is struck mute on the spot.
From one heavenly eye, to four eyes, to a whole sack filled with eyes, the horror escalates step by step.
Does that not sound very much like the Cthulhu mythos? Faced with a many-eyed being beyond human comprehension, the mind collapses at once. The difference is that the source of “Chinese Cthulhu” is not some unnameable thing from outer space. It is the deity you worship every day, the god at the corner of your own street. That feeling of the familiar becoming alien is precisely what makes it so chilling.
03 The Only Mortal Who Dared Look at His True Form
When ordinary people glimpse the true face of a higher being, both mind and body are usually unable to endure it. Yet history records one person who looked directly at Budai’s true form and did not break: his disciple Jiang Mohe, also known as Jiang Zongba.
Jiang Zongba had originally been a minor official in Mingzhou, present-day Ningbo, during the Five Dynasties. One day he received a report that a child had been swallowed by Budai’s sack. When the child was found, he had become vacant and dull, repeating only, “Inside it was all dark. There were eyes looking at me.” Jiang Zongba set out intending to arrest the monk, but Budai instead awakened him spiritually, and he immediately abandoned office to wander with him.
The strangest scene took place behind Xuedou Temple in Fenghua, Ningbo. In the dense fog of late autumn, master and disciple were bathing when Jiang Zongba noticed that Budai’s back did not resemble a human back at all. It looked more like old tree bark, marked with several dark red scars. When he reached out to touch one, the scar split open and revealed four eyes glowing with a blue-green light.
Jiang Zongba later said that in that instant his head rang, as if countless needles had driven into his temples, and his vision went black. Budai stopped him and told him that their karmic bond had reached its end. Jiang Zongba needed a full three days before his mind returned to normal. Before Budai died, he entrusted him with a wooden box containing a small cloth sack and left behind a prophetic line: “I do this in the hope that your descendants may endure like these objects I leave behind.”
04 The Hundred-Year Fate of the Jiang Lineage
A thousand years later, that sentence acquired an eerily concrete echo.
Readers with a feel for history may already have guessed where this leads. Jiang Zongba’s bloodline eventually produced a figure who would shape modern Chinese history: Chiang Kai-shek.
In 1948, Chiang personally oversaw the revision of the Genealogy of the Jiang Clan of Wuling, explicitly naming Jiang Zongba as the second-generation ancestor of the Wuling Jiangs. He took the Budai legend extremely seriously all his life. His diaries mention Jiang Zongba repeatedly, and he even had the “Mohe Hall” dedicated to him restored.
Popular rumor went further. It was said that when Mohe Hall was rebuilt in 1930, the statue of Budai inside had four eyes carved onto its back and normally concealed beneath a red cloth. On the eve of his retreat to Taiwan, Chiang allegedly visited Mohe Hall one last time and took away both a small Budai statue and the wooden box supposedly handed down from Jiang Zongba.
That line, “I hope your descendants may endure like these things I leave behind,” was thus given another deeply unsettling reading: that the descendants would be like objects stuffed inside the sack, unable to control their own fate, gathered and scattered only at the sack’s will. At the height of its power, the Jiang family seemed to hold the world in its hands. In the end it was confined to a single corner, as if trapped within that very sack.
05 Conclusion: An Endless Question Put to the Unknown
In truth, many Chinese folk deities that now seem wholly auspicious conceal a similarly terrifying underlayer.
Mazu is worshipped as a merciful sea goddess, yet there are also stories of fishermen who glimpsed her true form, half woman and half serpent, scaled from head to toe, and went mad. Many City Gods began as vengeful spirits who died with grievances unresolved. Even the character fu, pasted up for the New Year as a sign of blessing, originally carried an exorcistic force.
Beneath all these tales lies the fear ancient people felt toward an unknown world and a fickle fate. In an agrarian society, famine and plague were beyond control, and people needed a deity both dreadful and worthy of reverence to explain what surrounded them. Budai’s power to “swallow things” corresponds to famine. The eyes on his back correspond to pestilence.
When we look once more at that ever-smiling Budai Monk today, he may no longer be only a Buddhist image. He may also be the enduring question that Chinese culture has asked, for a thousand years, of the unknown itself.
