One modest county-level city southwest of Shaoxing holds two unrelated global monopolies: about 70% of the world's freshwater pearls (in Shanxiahu) and roughly a third of all its socks (in Datang). It is also, by legend, the birthplace of China's most famous beauty.
Zhuji was made a county in 222 BC, in the very first years of a unified China. It is, by tradition, the home of Xi Shi, the legendary 5th-century-BC beauty said to have helped the Kingdom of Yue undo its rival Wu. Watered by the Puyang River, it spent two millennia as fertile rice-and-fish country. What it has quietly become is something stranger: a single county that dominates two entirely unrelated world markets at once.
In the northeast of the county, the town of Shanxiahu grows and trades about 70% of the world's freshwater pearls and 80% of China's, from a footprint under 50 square kilometres. A trade that began with farmers selling raw pearls from roadside stalls is now a multi-billion-yuan business sold largely by livestream.
A few kilometres away, the Datang district makes socks: more than 25 billion pairs a year, enough to give every person on the planet roughly three pairs, which is about a third of the entire world's supply. What was once a cottage trade of women knitting at home became, town by town, a complete hosiery supply chain, from yarn to packaging.
Zhuji is a textbook case of Zhejiang's "block economy" (块状经济): the provincial habit of a single town specialising so completely in one product that the town and the product become the same thing. The recipe repeats: a traditional craft rooted in local agriculture or textiles; thousands of family workshops; a government-built wholesale market to gather buyers; and now livestream commerce to reach the world directly. Pearls and socks share nothing as objects, but everything as systems.
It is tempting to think of a manufacturing place as a single factory town. Zhuji is better understood as a constellation of specialised villages, each a near-monopoly in its own narrow good, held loosely together inside one county border. It is the whole logic of this atlas compressed into one administrative unit: not one city one industry, but one county, several worlds.
