Do you know where Marco Polo’s “Greatest Port in the World” really was?

Not Venice. Not Alexandria. It was Quanzhou. Europeans called it “Zayton.”

In 1087 AD, the Northern Song court established the Maritime Trade Bureau (Shibosi) in Quanzhou. Before that, the city’s overseas trade was managed remotely from Guangzhou. One imperial decree, and Quanzhou became China’s first special economic zone.

I’m Chuke. Today, I want to flip through the Quanzhou Prefecture Chronicles and the Quanzhou Customs Records, and see how this city managed global trade across two dynasties.

I. 15 Departments for One Port

The Shibosi headquarters sat inside Quanzhou’s Suqing Gate. How large was it? 15 functional departments, covering everything from vessel registration to cargo inspection to tax collection.

By 1115 AD (the 5th year of Zhenghe), the bureau had expanded: one Superintendent, multiple inspectors and secretaries, over 20 resident officials in total.

But these officials didn’t just collect taxes. Every time merchant ships departed or arrived, they organized grand “Wind-Praying Ceremonies” at Jiuri Mountain. The 78 stone inscriptions still standing there record these rituals—the earliest dates back to 1174 AD (the 1st year of Chunxi of the Southern Song), showing officials burning incense and praying for safe passage.

The Shibosi was customs office, foreign ministry, and religious authority rolled into one. Today we’d call it a “multi-functional government super-agency.”

II. Tax Rates Down to the Decimal

Quanzhou’s tax system was far more sophisticated than you’d expect.

During the Shaoxing period (1131-1162 AD) of the Southern Song, imported goods were taxed by category: fine goods like ivory and rhino horn at 20%; coarse goods like pepper and sapanwood at 10%.

On top of the “Choujie” (tax-in-kind), there was “Bomai”—mandatory government purchase of precious materials. In 1127 AD (the 1st year of Jianyan), Bomai revenue alone accounted for over 30% of the entire national maritime trade income.

Why both tax AND purchase? Because the court needed to control strategic resources. Ivory, rhino horn, ambergris—these weren’t ordinary commodities. They were state assets.

In 1170 AD (the 6th year of Qiandao), Zayton’s annual maritime trade revenue hit 2 million strings of cash (Guan). The Southern Song’s total national revenue at the time ranged from 40 to 60 million Guan. One port was generating one-thirtieth to one-fortieth of the entire empire’s budget.

By the Yuan Dynasty, the scale grew even larger. In 1289 AD, Zayton’s tax revenue reached the equivalent of 1,500 silver ingots—funding the Mongol Empire’s sprawling military campaigns and construction projects.

III. 41 Categories and the World’s Shopping List

Zayton wasn’t just a port. It was the material exchange hub connecting East Asia, Southeast Asia, the Indian Ocean, and the East African coast.

In 1974, a Song Dynasty shipwreck was unearthed at Houzhu Port. Its capacity: roughly 200 tons, 33 cargo holds, over 2,300 kg of fragrant woods. That’s just one ship. How many were coming and going every day?

In 1225 AD (the 1st year of Baoqing), Zhao Rukuo—a Shibosi official—wrote a book called the Zhu Fan Zhi (Records of Foreign Nations). It recorded 41 major categories of goods imported through Quanzhou: 12 types of fragrances (ambergris, frankincense), medicinal materials (dragon’s blood, myrrh), gemstones (pearls, cat’s eye)…

This wasn’t a local port’s shopping list. It was a global luxury goods map.

The export side was even more astonishing. The greater Quanzhou region (including Dehua and Anxi) boasted over 50 export porcelain kilns during the Song-Yuan period. The “Shin’an Shipwreck,” lost in 1323 AD, contained tens of thousands of Longquan celadon and Dehua white porcelain pieces. Some were stamped with “Daji” (Great Luck) or “Shisi” (Trade Bureau)—proof that the Shibosi conducted official quality inspections.

These ceramics reached 58 countries and regions. By the 13th century, “Made in China” had already gone global.

IV. Foreigners Came and Never Left

Trade boomed so much that foreigners simply stayed.

The Shibosi established a “Foreign Quarter” (Fanfang) in the south of the city. In 1109 AD (the 3rd year of Daguan), the local government even founded a “Foreign School” (Fanxue) for the children of foreign residents. In the medieval world, this level of cultural tolerance was extraordinarily rare.

By the Chunxi period (1174-1189 AD), Quanzhou had introduced a “Foreign Official” system—respected overseas merchants were appointed to help the Shibosi resolve disputes within the expatriate community. Think of them as the earliest “community liaison officers.”

The material legacy these merchants left behind still stands today. The Qingjing Mosque, built in 1009 AD (the 2nd year of Dazhong Xiangfu), is a classic example of Arabic architecture in China. Hundreds of Islamic, Nestorian, and Hindu stone carvings are scattered across Quanzhou, dating from the 11th to the 14th centuries.

Quanzhou’s legal system (the Shibo Tiaofa or Maritime Trade Laws) was sophisticated enough to handle cross-border civil and commercial arbitration. By 1277 AD, when Kublai Khan formally restored the Shibosi, Quanzhou’s rule-of-law standards rivaled any port in the world.

V. Globalization in Numbers

String these numbers together, and a clear picture emerges.

Established in 1087. 15 departments. 20-plus officials. Tax rates at 20% and 10%. Annual revenue of 2 million Guan—one-thirtieth of the national budget. 41 categories of imports. 58 export destinations. 50 kilns. 2,300 kg of spices. 1,500 ingots of silver.

These aren’t isolated statistics. They form the evidentiary chain of China’s deep engagement with pre-modern globalization.

The dusty data in the Quanzhou Prefecture Chronicles—tax items, cargo manifests, official titles, stone inscriptions—read them together, and you’re reading a condensed history of global trade.

When Marco Polo called Zayton the “Greatest Port in the World,” he wasn’t exaggerating.

Next time you’re in Quanzhou, visit the Suqing Gate site. 900 years ago, inside that gate, twenty-something officials in robes sat managing the world’s business.
