When people think of hot springs, most think of Japan.
But when I opened the Fuzhou Hot Spring Records, I found something that stopped me cold: there’s a Chinese provincial capital where you can soak in natural hot springs right in the city center.
And Fuzhou’s hot spring history predates Japan’s earliest written records by nearly five centuries.
I. The Hot Spring That Started It All (282 AD)
The story begins in the 3rd year of the Taikang era of the Jin Dynasty (282 AD).
Back then, Fuzhou wasn’t called Fuzhou. It was Jin’an Commandery. Governor Yan Gao was digging a moat when his shovel hit something unexpected—hot water. Not just warm groundwater. Scalding, steam-rising hot water.
That was the first time Fuzhou’s hot springs appeared in historical records.
I dug into the Fuzhou City Records and found a fascinating detail: Yan Gao didn’t fill in the spring. He incorporated it into the city’s water system. From day one of Fuzhou’s urban existence, hot springs were part of the plan.
Fast forward to the 9th year of the Zhenyuan era of the Tang (793 AD). Fujian Observation Envoy Wang Hong built the first public “Soup Pool”—a bathhouse open to both officials and commoners.
How rare is Fuzhou’s situation? The thermal storage area in its central city covers approximately 5 square kilometers. Among all provincial capitals on the planet, you won’t find another with hot springs bubbling up in the urban core.
II. The 82°C Underground Secret
Why is Fuzhou’s water so hot?
The answer lies deep underground. Fuzhou sits in the Min River basin, sandwiched between two fault zones running northeast and northwest. In the 2nd year of the Zhiping era of the Northern Song (1065 AD), Cai Xiang—yes, the same Cai Xiang who wrote the Tea Record and built the Luoyang Bridge in Quanzhou—did something few people know about: he conducted the first systematic survey of the city’s hot spring distribution.
Cai Xiang couldn’t have known that his survey would prove crucial exactly 306 years later.
In the 4th year of the Hongwu era of the Ming (1371 AD), Fuzhou reinforced its city walls. The construction crews discovered that the main thermal vein was concentrated in one area—what’s now the East Gate. The entire East Gate district was developed into a dense network of hot spring wells, creating a geothermal corridor from Tangchi Lane to Shudou.
The numbers tell the story: core water temperature sits at 82°C year-round, with 46 explored wells mapped across the city.
82°C is hot enough to scald your feet. Fuzhou’s hot springs are the real deal—boiling water straight from the earth.
III. 1933: The Year of 40 Bathhouses
The commercialization of Fuzhou’s springs is the part locals are proudest of.
In 1861, Fuzhou opened as a treaty port. Foreigners arrived and discovered something extraordinary: the Chinese city had natural hot springs downtown. Foreign experts from the Mawei Shipyard would regularly hire sedan chairs to travel from the shipyard to the city center, just for a soak.
I actually laughed when I read the Fuzhou Customs Records—by the 1870s, soaking in hot springs had become the favorite social activity of Mawei’s foreign staff.
By 1933, Fuzhou had over 40 registered bathhouses. “Le Tian” and “De Tian” were the most famous. These places weren’t just for washing. They offered haircuts, back scrubbing, Chinese massage, and morning tea.
One bathhouse was a mini commercial complex. Forty of them strung together formed a “Thermal Economy” network covering the entire city.
IV. The Monastery Bathhouses
Fuzhou’s hot springs have another dimension: they’re tied to religion.
During the Xiantong era of the Tang (860-874 AD), temples like Longyu built dedicated “Bath Pavilions” next to the monks’ quarters. These weren’t tourist attractions—they were for the monks themselves. But they were also free for believers and traveling monks.
By the Tiansheng era of the Northern Song (1023-1031 AD), Fuzhou’s Buddhist community reached its peak, treating hot springs as an act of merit. You could burn incense, pray, and soak in a free hot spring before heading home.
Today, Fuzhou still preserves 12 sites of hot spring-related inscriptions and temple relics.
What I found fascinating in the Fuzhou Religious Records is the evolution: hot springs in Fuzhou traveled from “sacred space” (you had to perform “fragrant bath” rituals before sacrifices) to “secular bathhouse”—a complete circle. Religious concepts of purity became Fuzhou residents’ daily habit of visiting the bathhouse every morning.
V. One Pool of Water, Ten Thousand Miles of Nostalgia
The part of Fuzhou’s hot spring story that moved me most involves the overseas Chinese.
After the 1911 Revolution, overseas Chinese from Southeast Asia returned home to build mansions near the East Gate. These houses shared one feature: nearly every one had hot springs piped directly inside.
The Fuzhou Surname Records showed me a number that stopped me: in the 1920s, approximately 15% of overseas remittances went into hot spring infrastructure and related real estate. These returnees didn’t just want hot springs in their own homes—they built roads and pipelines so entire communities could share the hot water.
After 1980, with China’s Reform and Opening, overseas Fuzhounese invested in the first modern hot spring hotels. Government data shows that in the early reform era, 22% of foreign-funded projects in Fuzhou involved wellness tourism.
One hot spring connects millions of Min people across more than 100 countries. That’s not an exaggeration. Map the parks and schools donated by overseas community leaders, and you’ll see what “thermal economy” really means.
VI. 50 Words for Warmth
Fuzhou people have their own language for hot springs.
The 1815 rhyme book Qi Lin Ba Yin already recorded many reduplicated words describing water temperature and quality. In a 1982 dialect survey, linguists collected over 50 unique terms in the Tangbian area specifically for describing the sensation of soaking—words that have no equivalent in any other Chinese dialect.
Fuzhou people call it “Sā-tōung” (洗汤). The verb “wash” here retains its archaic Chinese usage. The temperature distinctions are astonishingly fine: “wēn wēn tàng” means water just hot enough to step into, while “gǔn gǔn shú” means almost too hot to bear.
Fifty-plus words, carving the human experience of geothermal heat into such fine detail. That’s how resilient this culture is—hot spring culture survived in the mouths of Fuzhou people for millennia.
From the first hot spring in 282 AD, to 46 mapped wells, to an 82°C core temperature—every number in the Fuzhou Hot Spring Records tells me the same thing: Fuzhou didn’t discover hot springs. Fuzhou was built on top of them.
Those wells, bathhouses, and stone inscriptions aren’t urban amenities. They are the city’s real skeleton.
On chinaroots.org, I’ve marked every well’s history on a digital map.
Not for nostalgia.
So that everyone who opens the map can feel it—the warmth rising from underground has never cooled down.
