A friend of mine works in digital heritage preservation.

A while back, he told me something that stopped me cold. He said: “Crack open a Ming dynasty local gazetteer. You’ll see more of Quanzhou in one afternoon than in three days of walking the old city.”

I called bullshit.

He said: go read the Wanli Quanzhou Prefecture Gazetteer.

So I did. Not one volume. Thirty-three. From the Ming-era Wanli Gazetteer, through the Qing-era Qianlong Gazetteer, all the way to the modern Quanzhou City Chronicles series — administration, customs, religion, overseas Chinese, dialect, agriculture, education, water conservancy. One by one.

When I finished, I had one thing to say to that friend: you weren’t exaggerating.

I. In 2021, the World Looked at Quanzhou. They Only Saw the Tip.

July 25, 2021. “Quanzhou: Emporium of the World in Song-Yuan China” was inscribed on the UNESCO World Heritage list.

Twenty-two heritage sites. Kaiyuan Temple. Qingjing Mosque. Luoyang Bridge. Jiuri Mountain. The Shibosi ruins.

The world saw those 22 spots.

But after reading 33 gazetteers, I realized: the real Quanzhou isn’t in those 22 spots. The real Quanzhou is hidden in the grooves of stone inscriptions, in customs tax ledgers, in genealogies filled with names, in a single sweet potato that crossed the ocean from the Philippines.

Today, I’m going to show you that Quanzhou. The one you’ve never seen.

II. How Big Was This Port? Marco Polo Was Stunned.

Start with a cold fact.

Quanzhou’s international name during the Song-Yuan era was “Zayton.” Marco Polo wrote something in his travelogue that still blows my mind: “The pepper imports at Zayton are a hundred times those of Alexandria.”

A hundred times.

Imagine one port handling 100 times the foreign trade volume of another world-class port. That’s not exaggeration. That’s what Song-dynasty Quanzhou actually was.

How did they pull this off? One institution: the Shibosi — the Maritime Trade Office.

In 1087 CE, the Northern Song court established the Shibosi in Quanzhou. This was China’s fourth national-level maritime trade administration, after Guangzhou, Mingzhou (Ningbo), and Hangzhou. These four offices formed the institutional backbone of the Song Maritime Silk Road.

According to the Wanli Gazetteer, the tax system was shockingly sophisticated. Imported goods were subject to choujie — an in-kind levy — ranging from 1/10 to 1/15 of the cargo value. Every departing vessel had to obtain a gongping — an official permit listing crew names, cargo manifests, and destinations. No gongping? Your ship doesn’t leave.

Is that a customs office? Yes. That’s the Song dynasty’s customs office.

But the system’s fate was brutal. The Ming-Qing transition brought repeated flip-flops on the maritime ban. In 1757, the Qianlong Emperor decreed that Guangzhou would be China’s sole legal port for foreign trade. Quanzhou was officially out.

Officially.

The unofficial trade? It never stopped. The gazetteers are full of anti-smuggling memorials and local court disputes that give away the game. Ban on paper, boats on water.

Today, Quanzhou Customs has evolved from cargo inspection into the export backbone of Quanzhou’s hundred-billion-yuan industrial clusters — textiles, footwear, petrochemicals. The sneakers you’re wearing? They probably shipped through Quanzhou.

III. One Sweet Potato Rewrote Fujian’s History

If the Shibosi was Quanzhou’s “institutional code” for trade, then the traded goods themselves were the “physical carrier” of its influence.

Everyone knows Dehua white porcelain. Pure white body, translucent, the Europeans called it “Blanc de Chine.” The Wanli Gazetteer states plainly: “Dehua kiln wares are sold across the oceans.” And were they ever. You find them in Southeast Asian shipwrecks. In European castles. Everywhere.

Major exports also included Anxi Tieguanyin tea and Quanzhou satin (“Zayton satin”). Imports? Aromatics — frankincense, myrrh, ambergris — plus pepper, ivory, rhinoceros horn, coral.

But the thing that hit me hardest wasn’t any luxury good. It was a sweet potato.

The Quanzhou City Agricultural Chronicle records a small event: during the Wanli reign, a merchant from Changle named Chen Zhenlong brought a crop back from Luzon (the Philippines) — gan shu, the sweet potato. He trial-planted it at home, then spread it through Quanzhou across the entire province.

Do you understand what that meant?

Sweet potatoes are extremely drought-resistant and high-yield. Introducing them meant that the hilly, previously unfarmable inland terrain could suddenly support human life. Fujian’s population carrying capacity jumped a whole tier. One tuber traced a lifeline from Luzon to Zayton Port to the entire southeastern coast of China.

This wasn’t trade. This was civilizational gene exchange.

IV. Seven Religions, Three Square Kilometers, Zero Wars

Here’s something you probably don’t know.

Within less than three square kilometers of Quanzhou’s ancient city core, you’ll find relics of Buddhism, Islam, Daoism, Catholicism, Manichaeism, Hinduism, and Judaism — side by side. UNESCO calls Quanzhou a “World Religions Museum.” Not because of how many religious buildings it has, but because they’re right next to each other and nobody destroyed anybody.

The Quanzhou Religious Chronicle documents every one of them.

Kaiyuan Temple, founded in 686 CE. Its surviving twin stone pagodas, built during the Southern Song, are masterpieces — over forty meters tall, octagonal, five-tiered, their bas-reliefs blending Jataka tales with Hindu iconography. You’re looking at a Buddhist pagoda and spotting Hindu deities carved into it. That’s Quanzhou’s tolerance in stone.

The Qianlong Gazetteer calls Quanzhou the “Buddhist Kingdom of Southern Min.” Not an exaggeration. The temple registry alone lists over three hundred named sites.

The Islamic imprint is just as deep. Qingjing Mosque, founded in 1009 CE, bears Arabic inscriptions on its lintel recording its construction date and patrons. It’s China’s oldest surviving Arabic-style mosque. And the Sacred Tombs on Lingshan Mountain — traditionally the resting place of two of the Prophet Muhammad’s disciples — still draw Muslim pilgrims from China and abroad.

The maritime faiths are thick here too. Tianhou Temple, dedicated to Mazu, was founded in 1196 CE. The Qianlong Gazetteer painstakingly records every imperial canonization — from “Lady” to “Heavenly Consort” to “Heavenly Empress,” accumulating over thirty characters of honorific titles.

Every year, on Mazu’s birthday (23rd of the third lunar month) and ascension day (9th of the ninth lunar month), Tianhou Temple isn’t just a local worship center — it’s the most important spiritual bridge for cross-strait Mazu devotion.

V. Nine Million Overseas Quanzhou People, All on One Map

For the users of chinaroots.org, the Quanzhou Overseas Chinese Chronicle is the most direct bridge between past and present.

Quanzhou is one of the world’s most famous hometowns of diaspora. Over nine million people of Quanzhou descent live abroad, spread across more than 130 countries.

When I read the Overseas Chinese Chronicle, what hit me wasn’t the absolute numbers. It was how precisely mapped every migration route was — with clear spatiotemporal coordinates.

Starting in the mid-Ming, Quanzhou people moved out along two lines: one south to the Nanyang — the Philippines, Indonesia, Singapore, Malaysia — for trade and settlement; one east to Taiwan — after Koxinga recaptured the island, waves of Quanzhou soldiers and civilians relocated there. The chronicle estimates that over 200,000 Quanzhou natives migrated to Taiwan during the Kangxi-Qianlong period alone.

Go to Taiwan today. The dominant accent of Minnan there? Quanzhou dialect. Two hundred thousand people reshaped an island’s linguistic landscape.

And these people didn’t just leave. From the late Qing through the Republican era, overseas Quanzhou poured money into education — Peiyuan Middle School, Quanzhou No. 5 Middle School, Huiming Middle School, all founded or funded by overseas Chinese. The Water Conservancy Chronicle lists dozens of dams and canals built with diaspora donations.

The land raises the people, and the people give back to the land. These 33 gazetteers aren’t books. They’re ledgers — entry by entry, recording who did what for their hometown.

VI. Read Tang Poetry in Quanzhou Dialect and the Rhymes Just Work

Let me end with the thing that fascinated me most: the Quanzhou dialect.

According to the Quanzhou Dialect Chronicle, Quanzhou Minnan has 14 initials, 82 finals, and 7 tones — one of the most complex phonological systems in any Chinese dialect.

But that’s not the point. The point is that Quanzhou dialect preserves two defining features of Middle Chinese: a complete set of nasal codas (-m, -n, -ŋ) and entering-tone stop codas (-p, -t, -k, -ʔ), plus a unique evolutionary path where voiced obstruents devoiced into unaspirated voiceless sounds.

“Why doesn’t this Tang poem rhyme in Mandarin?” — because Mandarin dropped the entering tones. Read it in Quanzhou dialect, and the rhymes click back into place, naturally, without any annotation.

For diaspora root-seekers, this means something concrete: the accent your grandparents passed down — it corresponds to a specific county, a specific village, recorded in these gazetteers. It can be pinpointed.

That’s what digital humanities can do.

Closing

From the woodblock prints of Wanli, through the supplementary redactions of Qianlong, to the systematic 33-volume enterprise of the modern era — four centuries of inscription left Quanzhou an unrivaled civilizational archive.

I spent over a month reading all 33 volumes.

Honestly, I started with a “fact-finding” mindset. But by the end, I felt like I was reading a city’s actual biography. Not the glossy version you get in a travel brochure. A three-dimensional, complex, living Quanzhou — built from customs ledgers, stone inscriptions, phonetic charts, and remittance letters.

For chinaroots.org, this data isn’t dead. It’s waymarkers.

Whether you’re a scholar tracing the Maritime Silk Road’s trade networks, or a descendant following ancestral footsteps across oceans, every line in these gazetteers can lead you to a specific, tangible coordinate in space and time.

That coordinate is called Quanzhou.
