A douli is the conical bamboo hat that Chinese farmers wore in the rice fields for something like two thousand years. It is built from split bamboo, a layer of palm fibre, and a coating of tung oil, and a good one weighs about as much as a paperback. The best-known ones now come from Zhongfang county in Huaihua, Hunan, a place that calls itself the home of the bamboo hat and where the craft was listed as a provincial intangible cultural heritage item in 2006. What follows is how one is actually made, and why a machine has not taken the job over.
What It Is, and How Old
The reference everyone cites is the Book of Songs: “what raincoat, what hat” — he suo he li — from a poem roughly two and a half millennia old. The form has not changed much since: a shallow cone, wide enough to cover the shoulders, worn over a rain cape of straw or palm.
There are two basic crown shapes, pointed and rounded. The good ones use the outer skin of the culm — zhu qing, the green layer, which is the tough part — for the working surface, with rattan or a split bamboo hoop at the apex and around the rim. Between the two woven layers goes a filling: traditionally bamboo or arrowroot leaves, or oiled paper, and in the Zhongfang version a circle of fine palm fibre at the lower edge and a piece of printed cotton at the top. Then the outside is sized, painted, and brushed with tung oil.
That is the whole design: two woven shells, a waterproof filling, an oil finish. Everything else is refinement.
Zhongfang, and the Story the County Tells
Zhongfang county in Hunan is the centre that survived. Local accounts put the origin of its hat in the Han dynasty and its height in the Ming and Qing, with a separate tradition that the weaving began some five hundred years ago in Bajiao village. The story the county repeats is that in the Qianlong reign a man from Jingping village named Pan Shiquan, who held a post at the imperial astronomy bureau, brought a Zhongfang hat back to court; the emperor is said to have approved of it, and it became a tribute item.
The craft entered Hunan’s first provincial intangible cultural heritage list in 2006. Two related items were listed at provincial level in 2012: the “Red Army hat” in Jiangxi — because weavers in the war years are said to have worked five-pointed stars into the weave for soldiers — and the Miao horsetail hat in Guizhou.
In the 1980s and 1990s the trade was still substantial: hats went to Singapore, Japan, the United States and Finland, and the horsetail version, with real horsetail hair laid between the layers, was rare enough to be given as a courtship gift.
Eighty-One Steps, Nineteen Tools
The figures quoted in Zhongfang are nineteen tools and eighty-one steps. Some accounts give “more than thirty” core steps instead, and the honest thing is to say that both numbers circulate and the larger one counts subdivisions. The sequence, in the order the workshops describe it:
Select and fell the bamboo — mainly water bamboo (shui zhu), with mao bamboo for the ribs and peach bamboo for the rim hoops. Split the culm into strips. Separate the green skin from the yellow inner layer, which is more brittle and is not used for the working surface. Split again into thin strips. Then comes the step that decides the quality of the whole hat: gua mie, drawing each strip back and forth through the scraper — eleven passes is the figure given — until it is even, smooth and thin enough to weave.
Then the two shells are woven, inner first, using a two-over-one-under interlace. The classic Zhongfang hat is described as three layers: inner and outer shells of woven bamboo, with printed cotton between them at the top and a ring of palm fibre at the bottom. The shells are joined and the rim bound, then the surface is sized, a paper flower or printed motif applied, the apex brushed black, and the whole hat oiled and sun-dried.
A finished hat is around sixty centimetres across and roughly three hundred grams. It is light enough to forget you are wearing it, rigid enough to keep its shape in rain, and it breathes, which a plastic hat does not.
Why the Bamboo Has to Be Chosen That Way
Weaving uses the green outer layer because that is where the fibre runs densest and the strength is. The yellow inner layer is softer and more brittle and is stripped away. This is why splitting is done by hand: the cutter has to read each culm and decide where the usable layer ends, and it is not at the same depth on a young culm and an old one.
Water bamboo is preferred because it grows in wet ground and produces long, even, flexible splints. Harvest timing matters too — bamboo cut in the wrong season carries more starch and attracts insects, which is a problem for an object meant to get wet and then be stored.
The tung oil at the end does the waterproofing. Tung oil polymerises as it cures rather than simply drying, which is why a properly oiled hat sheds water for years instead of a season.
Why Nobody Has Mechanised It
This is where the engineers get interested, so it is worth being precise about what actually blocks mechanisation. It is not sentiment.
Xiang Shaoju, a weaver in Zhongfang who is often named as one of the faster hands in the county, was asked directly whether a machine could do it. “No,” she said. “The splints differ in thickness and in flexibility. Every bamboo is different. A machine can only make things that are uniform.”
That is the whole argument. A loom or a mould can produce a regular object from regular material. It cannot take a material whose properties vary piece to piece and adjust the tension, the split depth and the spacing accordingly as it goes. The skill is not speed; it is continuous correction against variable material, and that is exactly the part a machine specification assumes away.
There is also a finishing problem: the last operations — sizing, painting the apex, oiling — are done on an object whose surface tension changes with humidity, and they are judged by eye.
What It Costs Now, and What Has Actually Changed
The market went first. A plastic hat costs a few yuan, weighs less, and does not need oiling, and it took the fields years ago. One Zhongfang maker, Zeng Fanen, puts it plainly: now mostly only older people still farming buy one. The hat has moved from equipment to craft object, and the workshops that remain sell on quality and on the fact that it is still made by hand.
The labour problem is the real one. Xiang Shaoju has tried teaching younger relatives and says the longest lasted under two weeks — the work blisters your hands before you are any good at it, and it is quiet and slow. Zeng Fanen had a young man come from out of town and study for three months, and he was getting competent when he left for family reasons and did not come back.
Zeng’s own position is worth quoting because it cuts against the usual preserving-the-tradition framing: if young people do not like the old styles, he says, then make what they like — as long as they still wear a douli. Whether it looks like the one he made in his twenties does not matter to him.
Buying One, and Living With It
Four things separate a woven hat from a decorative one.
Hold it up to the light. A real douli shows the interlace and, at the lower edge, the palm fibre packed between the layers. A decorative version is a single woven shell, or a moulded plastic shape printed to look woven.
Weigh it. Around sixty centimetres across and about three hundred grams is the Zhongfang figure. Something noticeably heavier for the same diameter is using thicker splints or a different construction; much lighter and it has no filling.
Look at the finish. Tung oil gives a warm, slightly amber surface that darkens with age. A high-gloss, evenly sprayed coating is usually lacquer over a thinner weave.
Check the rim. The binding is where a hat fails first, and on a well-made one it is tight and even all the way round.
On care: dry it before storing, never folded or crushed, out of direct sun for long periods because bamboo splits when it dries too fast, and re-oil it when the surface starts to look chalky. Treated that way it will last for years; neglected, the splints go brittle and the rim loosens.

- Hunan Daily / Xin Hunan and China Internet Information Center reporting on Zhongfang douli, including interviews with weavers Xiang Shaoju and Zeng Fanen.
- Recorded descriptions of the process: nineteen tools, eighty-one steps (with “more than thirty” also in circulation), eleven scraper passes, two-over-one-under interlace, three-layer construction, approximately 60 cm and 300 g.
A note on this article’s earlier version: it cited four sources claiming peer-reviewed and industry research on bamboo weaving and composites, including a paper in Advanced Sustainable Systems and reports attributed to UNESCO, ResearchGate and Statista. We were not able to verify any of them, and they have been removed. It also described the authors as having conducted decades of fieldwork among bamboo artisans, which was not true. What is stated above rests on the provincial heritage listing and on named press interviews, both of which can be checked.
