Chinese Brushes: Wolf Hair, Goat Hair and the Four Virtues

A guide to Chinese brushes: wolf hair against goat hair, how a maobi is made, the four virtues worth testing for, and how to care for one properly.

Press a good Chinese brush onto a sheet of paper and lift it, and the hairs should come back to a single point on their own. That recovery is not a detail of manufacture — it is the property the whole tool is built around, and it is what allows one brush to draw a hairline and a two-inch wash without being changed. A brush that has lost it, or never had it, will produce a splayed and forked stroke no amount of skill can rescue.

This guide covers what Chinese brushes are made from, how the standard hair types behave differently under the hand, how a brush is assembled, and what to check before buying or using one. It is the fourth of the scholar's tools, alongside ink, paper and inkstone, and it is the one that most directly limits what a painter can do.

The four virtues

Chinese brush-making is judged against four criteria, stated so consistently over the centuries that they function as a specification. A brush should be:

Pointed. It comes to a fine, single tip when wet. Test it by wetting the head and looking at the tip against the light.
Even. The hairs align so that the tip opens into a straight edge. Flatten the wet tip with a finger; the edge should be level rather than ragged.
Round. The belly is full and symmetrical, with no hollows. Roll the head between your fingers and look for gaps.
Resilient. It springs back to a point after pressure. Press down on paper and release.

These are worth memorising because they give you a fast, non-technical way to assess a brush you have never handled. Three of the four can be checked in a shop with nothing but water. Resilience is the one that separates the acceptable brush from the good one, and it is largely a function of the hair.

Hair types and what they do

Almost everything you will meet falls into three families, and the difference between them is stiffness.

Wolf hair (langhao) is the stiff option. Despite the name it does not come from wolves — the standard material is the tail hair of the yellow weasel, and the "wolf" of the name is a translation artefact that has stuck. It is springy, holds a sharp point, and returns to that point aggressively. It gives you control and a crisp line, and it is the usual choice for detailed work, for outline drawing, and for the fine strokes in meticulous painting. It holds less water than soft hair, so strokes run dry sooner.

Goat hair (yanghao) is the soft option. It absorbs far more water and ink, which makes it the brush for washes, broad areas, and long strokes that must not run out halfway. Because it is soft, it transmits pressure changes readily — small movements of the hand produce large changes in the mark. That makes it expressive and difficult; a goat brush punishes an unsteady hand in a way a wolf brush does not. Most large brushes are goat hair for the simple reason that stiff hair in that volume would be unusable.

Mixed hair (jianhao) combines the two, typically with a stiffer core wrapped in softer outer hair. This is the compromise brush, and for most people beginning to paint it is the sensible one: enough spring to keep a point, enough absorbency to carry a stroke. A very large share of general-purpose brushes sold today are some form of mixed construction.

Other hairs appear — horse, rabbit, weasel variants, and the occasional specialist material — but the stiff/soft/mixed division is the one that governs how a brush behaves, and it is the question to ask first.

The relationship between brush and paper matters as much as the brush itself. A soft goat brush loaded with ink behaves completely differently on raw absorbent paper than on sized paper, and choosing them independently of each other is the most common beginner's mistake. The sizing question is set out in our guide to xuan paper.

How a brush is put together

A finished brush looks simple and is not. The hair is sorted by length and quality, aligned so that the natural tips — not cut ends — all point the same way, and built up in layers around a core. Getting every tip to arrive at the same place is the entire craft, and it is why the pointedness virtue is the hardest one to manufacture consistently.

The assembled bundle is bound at the base, glued, and set into a hollow handle, traditionally bamboo, though hardwood, lacquer, porcelain and horn all appear on better or more decorative brushes. A new brush usually arrives with the head stiffened by a water-soluble sizing that protects the tip in transit. That sizing must be soaked out in cool water before first use — working with it still in place will break hairs and can ruin the brush permanently.

Brush-making is regionally concentrated in the same way the other scholar's materials are. Huzhou in Zhejiang is the name most associated with fine brushes, as Jing County in Anhui is with paper and Huizhou with ink. The four tools form a linked system with linked origins, which is why they are treated together as a set — the connections are traced in our overview of the four treasures of the scholar's studio.

Using and caring for one

Most brushes are destroyed by their owners rather than worn out, and almost always in the same three ways.

Dried ink at the base. Ink that is not washed out settles at the root of the head, hardens, and progressively kills the brush's flexibility from the inside. Wash until the water runs clear, working the ink out of the base rather than just rinsing the tip.
Standing on the tip. Leaving a brush resting on its head, wet or dry, bends the hairs permanently and destroys the point. Brushes are hung head-down or laid flat on a rest.
Hot water and soap. Both attack the glue and the hair. Cool water only.

Store a brush dry and hanging, and let it dry naturally rather than forcing it. If you use a brush roll, make sure the head is completely dry before rolling, or you will grow mould in it.

A practical note on how many brushes you need: fewer than sellers suggest. A medium mixed-hair brush, one small stiff brush for detail and inscription, and one large goat brush for washes will cover most work. Range in Chinese painting comes from how a single brush is loaded and angled, not from swapping tools — a single well-made brush can produce a line finer than a pen and a stroke wider than a hand, which is precisely the point of the pointed-and-resilient specification.

The clearest demonstration of that range is Qi Baishi's shrimp. The bodies are built from a few translucent, graded strokes and the antennae are single hairlines drawn at speed, all from a brush that has to move between those two extremes without being reloaded or replaced. Qi Baishi is worth studying for this reason alone, and the effect is easy to read in his shrimp paintings. How the brush is held and driven — from the shoulder and elbow rather than the fingers, with the shaft upright — is part of the same system, and it is what makes the long even strokes in freehand work possible at all. The two modes of painting this serves are compared in xieyi and gongbi.

Buying: what actually matters

Price in brushes tracks hair quality and the labour of sorting it, and both are invisible in a photograph. Buying online without handling is therefore genuinely difficult, and the sensible approach is to buy inexpensive brushes until you know what you like, then buy well once.

Check the four virtues if you can handle the brush. If you cannot, prefer a maker or shop with a reputation to protect over an unbranded bulk listing, and be suspicious of very large brushes at very low prices, since volume of good hair is exactly what costs money. Ignore the handle. Decorated porcelain and carved handles add cost and nothing to performance, and an elaborate handle on a cheap head is a reliable sign of where the maker put the budget.

Common questions

What brush should a complete beginner buy?

One medium-sized mixed-hair brush. It will let you make both a controlled line and a loaded wash while you work out which direction you want to go, and it is forgiving in a way that neither a pure goat nor a pure wolf brush is. Add a small stiff brush when you start doing detail or writing inscriptions, and a large soft one when you start working at scale.

Why does my new brush not come to a point?

Most likely the sizing has not been fully removed. Soak the head in cool water until the stiffener dissolves completely and the hairs move freely, which can take several minutes. If it still will not point after that, the brush is poorly made — the tips were not properly aligned during assembly, and no amount of use will fix it.

How long should a brush last?

With proper washing and storage, a good brush lasts for years of regular use. Hair does wear, the tip gradually loses its edge, and heavily used brushes are eventually retired to rough work rather than thrown out. A brush that dies within months has almost always been killed by ink left at the base.

Is wolf hair better than goat hair?

Neither is better; they do different jobs. Stiff hair gives control and crispness, soft hair gives capacity and expressive range. Most painters own both, and mixed-hair brushes exist precisely because the trade-off is real. If someone tells you one type is simply superior, they are describing their own working preference rather than a property of the material.
