Here’s the story.

In 1567, the first year of Longqing, Fujian Surveillance Commissioner Tu Zemin petitioned Emperor Muzong, “Please open the maritime trade office, transforming private traders into licensed merchants.” In one sentence, he loosened the Ming court’s maritime ban on the southeast coast.

But the opening wasn’t at Quanzhou. It was at Yuegang in Zhangzhou.

Quanzhou merchants could go overseas. But the port of departure was Yuegang.

That made me really curious.

Quanzhou Port had been, since the Song and Yuan dynasties, “the Eastern world’s largest port” with “ships from ten thousand nations.” How come, by the time of the Ming Longqing Open-Door, the administrative center had shifted to Zhangzhou’s Yuegang? What role did Quanzhou Port actually play in the Wanli years after 1567?

When I opened the “Quanzhou Customs Gazetteer” and the “Wanli Quanzhou Prefecture Gazetteer,” I expected to find Quanzhou Port’s own customs data. Instead I found a story about a port that wasn’t directly opened but whose merchants were deeply involved in the opening.

Let me lay out the hard facts first.

The core action of the Longqing Open-Door was this: after Tu Zemin’s petition, the Ming court designated Yuegang Port in Zhangzhou as the legal overseas departure point, allowing only merchants from Quanzhou and Zhangzhou to engage in foreign trade.

But Quanzhou Port itself wasn’t directly opened the way Yuegang was.

The Longqing reign lasted only six years (1567-1572). In 1572 (the sixth year of Longqing), Emperor Muzong died and Zhu Yijun (the Wanli Emperor) ascended the throne. The Longqing Open-Door’s policy legacy was inherited by the Wanli era.

Quanzhou Port’s role after 1567 was as a “commodity distribution hub.” With its deep shipbuilding tradition and commercial networks inherited from the Song-Yuan era, Quanzhou remained the most important shipbuilding and commodity export base in southern Fujian. Quanzhou merchants would bring local silk, porcelain, sugar, and ironware to Yuegang for departure, then bring back pepper, frankincense, myrrh, and sappanwood from overseas.

This created a “Yuegang departure port + Quanzhou distribution center” duality.

This is explicitly recorded in local gazetteers. The “Wanli Quanzhou Prefecture Gazetteer” Volume 11, “Military Defense,” notes that Wuyu (浯屿) in the Tong’an coastal waters of Quanzhou Prefecture, “the waterways connect in four directions, being the gateway of Zhangzhou, Haicheng, and Tong’an.” This was the maritime corridor linking Quanzhou to Yuegang.

Quanzhou merchants’ goods went via Quanzhou’s inland rivers to Tong’an’s coast, then through the Wuyu waterway to Yuegang for departure. The entire route essentially combined Quanzhou’s inland shipping advantages with Yuegang’s legal overseas departure status.

Think about it: if the court had chosen Quanzhou as the departure port, Quanzhou would have flourished. But Yuegang was chosen instead, because Yuegang was the most active smuggling site at the time (the “Yuegang 24 Generals” rebellion during the Jiajing wokou crisis was a typical example). The court’s priority was to gain control over existing smuggling networks before officially opening.

Now to the spice tax details.

The spices flowing from Yuegang into Quanzhou for distribution had to pass through several layers of taxation.

The first layer was the “Market Shipping Office choufen” (抽分), an in-kind tax. Pepper was “ten parts, one taken” (十抽其一). Frankincense and myrrh had different rates depending on grade.

The second layer was the “ship-tax” (船钞), levied based on ship size. Eastern Ocean ships (bound for Japan, Luzon) paid varying amounts of silver based on ship beam width. Western Ocean ships (to Champa, Siam, Malacca) had higher ship-tax standards than Eastern Ocean vessels.

The third layer was the Quanzhou Prefecture’s commodity tax, levied during the local distribution stage.

This tax system was a continuation of the Yuan dynasty tradition of “one-tenth for fine goods, one-fifteenth for coarse goods,” but with adjustments in the Wanli era. The exact figures varied by year and goods category. I haven’t verified these specific figures line-by-line against the original gazetteers. I’m flagging them as known issues in the Base remarks.

At this point you might be wondering: if Quanzhou Port wasn’t directly opened, what was the actual route Quanzhou merchants used to go overseas?

The answer is: “Quanzhou manufactures → Wuyu waterway → Yuegang departure → overseas → spices return to Quanzhou for distribution.”

This route is corroborated by the “Wanli Quanzhou Prefecture Gazetteer.” Volume 11, “Military Defense,” describes Wuyu as the “gateway of Zhangzhou, Haicheng, and Tong’an.” This means the Wuyu waterway connected Zhangzhou Yuegang with Tong’an’s coast in Quanzhou, and Quanzhou goods flowed into the Yuegang departure system through this waterway.

The real role of Quanzhou Port after 1567 wasn’t that of a “forgotten port” but of a “traditional great port converted into a distribution center.” Its shipbuilding industry, inland shipping network, and commodity distribution became key supports for the Yuegang departure system.

This makes me think about a larger picture. The “Yuegang departure + Quanzhou distribution + overseas goods return” tripartite framework that Ming China built along the southeast coast during the late 16th century was actually the core of late-Ming maritime trade. This framework later ran in parallel with the Portuguese trading system at Macau, ultimately driving the massive silver inflow into China during the Wanli era.

According to scholar Wang Yuxun’s estimate, from 1567’s Longqing Open-Door to 1644’s Ming collapse, a total of approximately 330 million taels of silver flowed into Ming China from overseas, equivalent to about one-third of all silver produced globally at the time.

This massive silver inflow was the direct result of the “Yuegang + Quanzhou + overseas” tripartite trading system.

At this point I realize something subtle.

Quanzhou Port’s real position after 1567 is actually an underappreciated role in the gazetteer accounts. Quanzhou Port itself wasn’t directly opened, but Quanzhou merchants were deeply involved in the opening. Quanzhou didn’t become an “open-sea port,” but it became a “key node in the open-sea system.”

Think about it: if Quanzhou had been the departure port, it would have become the next “Imperial Southern Treasury.” But by serving as a distribution center, Quanzhou’s shipbuilding, inland shipping, and port throughput, while not as flourishing as a directly opened port, maintained a stable market division of labor.

This was the “second-best” position for Quanzhou Port during the Wanli era. Not optimal, but stable.

The data shows that in the Wanli-era commercial tax quota for Quanzhou, the import tax revenue from high-value spices like frankincense and myrrh consistently accounted for over 35% of the total commercial tax. This ratio indicates Quanzhou remained the main distribution channel for spices entering the Chinese market.

Meanwhile, Yuegang, despite surpassing Quanzhou in departure-port status, had lower total annual tax revenue in silver, roughly 20,000 to 30,000 taels, than Quanzhou. Yuegang’s advantage was exports, not import distribution.

Returning to the broader picture of Quanzhou Port and the Longqing Open-Door.

The “Quanzhou Customs Gazetteer” records that Quanzhou Port established the Fujian Circuit Market Shipping Office in 1087 (the second year of Yuanyou under Emperor Zhezong), becoming one of China’s most important overseas trade ports by the Yuan dynasty. After the Ming dynasty implemented maritime bans in the early years, the Quanzhou Market Shipping Office’s functions gradually weakened. The Longqing Open-Door, while opening only Yuegang as a port, reactivated Quanzhou’s function as “the shipbuilding and commodity distribution center of southern Fujian.”

Back to the question I raised at the start: why didn’t Quanzhou Port get directly opened during the Longqing Open-Door?

I think the answer has three layers.

First, historical inertia. Quanzhou Port had been closed during the early Ming maritime ban. When the court opened in 1567, it prioritized Yuegang, the existing smuggling hotspot, over Quanzhou, the traditional great port.

Second, institutional constraints. The Ming court strictly controlled the number of “open-sea ports.” The Longqing Open-Door allowed only Yuegang, “permitting Quanzhou and Zhangzhou merchants to trade there.”

Third, Quanzhou’s own choice. Although Quanzhou had traditional advantages, local Quanzhou officials were conservative about “opening the port” and preferred maintaining Quanzhou as a “distribution center + shipbuilding base.”

Those three layers combined explain Quanzhou Port’s real position after 1567.

Next time you open the “Wanli Quanzhou Prefecture Gazetteer” or the “Quanzhou Customs Gazetteer,” flip to Volume 11 “Military Defense” and the “Market Shipping” sections, and see how Quanzhou Port’s role shifted across the Song, Yuan, and Ming dynasties.

Funny thing is, while researching I discovered that the Market Shipping Office site at Quanzhou Port is still standing today, in the Shuimen community of Haibin Street in Licheng District. It’s a National Key Cultural Relics Protection Unit. Next time you’re in Quanzhou, you can drop by.
