I. The Prescription Written in 1381

Here’s a number: 1381.

That year, Emperor Zhu Yuanzhang issued a decree. At the busiest intersection of Zhangzhou city, a “Huimin Pharmacy” — a public pharmacy — opened its doors. It treated epidemics. It gave out free medicine. It saved poor people’s lives.

Now open a map of modern Zhangzhou. That exact spot? Still a hospital. Four hundred years later, the coordinates haven’t moved.

According to the Zhangzhou Fu Zhi compiled in 1573 AD (1st year of Wanli) under Prefect Luo Qingxiao, medicine was serious business — integrated into the “Products” and “Biographies” chapters not as decoration, but as a pillar of population growth and social stability. The chronicle runs 32 volumes. Every volume has a medical footprint.

By the 1570s, all 7 counties of Zhangzhou had their own public pharmacies. Each one staffed with a quota of medical students and administrators. A Ming-era public health network, fully operational.

II. The Epidemic Year 1565

1087 AD, Northern Song. Zhangzhou recorded its earliest official health intervention — during school and waterway construction. A footnote in the chronicle.

The real test came in the Ming.

During the Jiajing and Wanli eras, epidemics hit the southeast coast hard. The chronicles record how Prefect Luo Qingxiao mobilized private doctors to help.

1565 AD, 44th year of Jiajing. A disaster. Post-epidemic prevention. The chronicles’ Seismic Records cross-referenced with disaster logs: dozens of famous physicians were deployed.

Dozens. A verifiable number, with names, hometowns, and biographies recorded in the “Miscellany” volume.

III. Three Names, Three Biographies

Zhangzhou’s medical heritage runs through families. This is the starting point for tracing Min-nan medical lineages.

The Wanli chronicle’s “Biographies — Specialized Skills” volume gives us three names.

Qian Guxun, active in the 15th century. His biography is short, but it tells you what he treated and which formulas he used.

Chen Qimo, Jiajing era. The chronicle says he specialized in “Damp-Heat Theory” — which makes sense for southern Fujian. The climate is damp and hot. Disease follows. His works dominated the local medical catalog.

Lin Sike, Wanli era. He was contemporary with the chronicle’s compilation, so the records on him are more detailed.

The medical book catalog recorded in the chronicle shows that “Damp-Heat Theory” texts held a significant share. This isn’t academic curiosity. It’s the raw data of local disease prevention.

IV. 78 Stone Steles and 88 Ships

Here’s a more tangible clue: stone.

A total of 78 Ming and Qing stone steles survive in Zhangzhou, recording medical inheritance and temple renovations.

The earliest is dated 1603 — 31st year of Wanli. From that point, the gentry started writing medical charity into their clan’s public ledger. They built Medicine King Temples. They erected steles to record it. Each stele has a date, a donation amount, the donor’s name. Each one marks the intersection of a clan with medicine.

But Zhangzhou wasn’t just using its own medicine. Its geography made it the pharmacy of the entire southeast coast.

The “Products” volume of the Wanli chronicle states: the mountains of Pinghe and Nanjing produced Amomum and Poria; the ports of Haicheng and Zhangpu imported frankincense and myrrh. During the Longqing and Wanli eras, the Yuegang port authorized 88 trade vessels per year. They sailed out with silk and porcelain. They came back with spices and medicinal herbs.

“No medicine is complete without Zhangzhou” — that old saying isn’t folklore. It’s customs data.

V. 31 Sites, 400 Years of Overlap

In the 1980s, Zhangzhou did something smart: it began digitizing the sites and medical records of its historical physicians.

The result surprised everyone.

Researchers mapped the 31 Ming-era medical sites recorded in the Wanli chronicle and overlaid them on Zhangzhou’s modern medical map. The overlap was striking — the public pharmacy site aligned with the TCM hospital. The physicians’ residential areas aligned with community health centers.

The 400-year-old urban layout is still operational.

This isn’t romantic nostalgia. It’s computable, verifiable spatial data.

Today’s Zhangzhou pharmaceutical industry — Pientzehuang, Babao Ink, and the rest — traces its export volumes back to that same “Maritime Silk Medicine Road” established in the Wanli era.

VI. One Prescription, 400 Years

The medical records in the Wanli Zhangzhou Fu Zhi are more than ancient formulas. They are the foundation of a pharmacy built in 1381. The names of the dozens of physicians deployed in 1565. The silver amounts inscribed on 78 stone steles. The exotic spices brought back by 88 ships.

We take the three threads — medical administration, physician lineages, and the drug trade — and weave them into a single map. Every data point marks a spot where a family once practiced medicine, distributed drugs, or erected a stele.

The medical cases sleeping in those chronicles, the names weathering on clan steles, the medical coordinates that have been running for 400 years without a break — this is the health baseline that chinaroots.org is reclaiming, one data point at a time, for every Min-nan family.
