Artist Cai Jian / 蔡兼素描 (CJMSGZS): The Apple Drawn Without a Block-In
The paper is clipped to a wooden easel, and a tablet leans against its foot, showing a photograph: a skull, two apples, a folded cloth and a flat bristle brush on a worn plank. On the paper there is almost nothing yet — a few pale lines that place each object. Then the pencil goes to the skull’s eye sockets and presses them dark. Everything else in the drawing will be measured against those two holes.
The Artist
蔡兼 — Cai Jian — is a charcoal and pencil teacher from Guangdong who runs his own studio, 蔡兼美术. His work is 素描: the black-and-white drawing every Chinese art student has to master before anything else. He teaches it online and in person, travels around the country to lecture, and sums up his aim in one line: 让绘画变得简单有趣 — make drawing simple and fun.
A Teacher of the Foundations
Cai Jian’s students range from complete beginners who have never drawn to teenagers preparing for China’s art exams — the middle-school art test and the university entrance exam, where one still life in charcoal or pencil can decide which school they get into. That shapes everything he teaches. There is no mystery in his lessons and no talk of talent. Drawing is treated as a chain: geometry holds up value, value holds up the look of a material, and material holds up a complete picture. Break the chain anywhere and the drawing fails in a way that can be named.
He has also turned that chain into printed study material: 《蔡兼素描临摹本》, a copy book of his drawings for beginners, and sets of copy cards that start with single cubes and prisms and build up to full still lifes. A student can sit down with a card, copy it stroke for stroke, and see exactly where their version drifts.
Two Ways Into a Drawing
Chinese foundation training starts with 起形, the block-in: outline first, measure, correct, and only then fill in the tones. Cai Jian teaches that way, and he has a whole lesson on getting the block-in right in one move.
But he also draws an apple with no block-in at all. Working in charcoal powder with a charcoal pencil, he tones the sheet first, pushes the dark side in with more powder, lifts the light side back out with an eraser, and lets the outline appear last, as the place where two tones meet. Powder has no point, so it cannot make a line to begin with.
He jokes about the two camps — 炭笔派 and 炭粉派, the charcoal-pencil faction and the charcoal-powder faction — but the lesson underneath is serious. Nobody sees outlines in real life. Objects have edges where one tone stops and another begins. A student who has reached a shape from both ends, measured from the outside and found from the inside, understands what the block-in is actually for.
Drawing the Tools
He comes back again and again to brushes: a wide flat paint brush, and a Chinese writing brush lying across a stack of old books, next to a bowl of ink.
The writing brush shows his method step by step. On the top of the bristles, the hatching follows the direction of the hair. On the side, he lays vertical lines in one even pass to unify the tone. Then he takes a hard eraser cut into a triangle and draws light back into the bundle with its sharp corner. Last, a sharpened pencil cuts out the shapes of single hairs at the tip.
His one instruction for that tip is 注意画出参差不齐的感觉 — make sure it feels ragged. A beginner draws a neat tapered triangle, because neat feels like skill. But a real brush is thousands of hairs of slightly different lengths. Draw it tidily and you have drawn a shape. Draw it raggedly, with strays flying off the edge, and you have drawn hair.
Paper and Charcoal
Cai Jian draws with C先生 (Mr. C) charcoal pencils and paper, and he tells students so directly. It is more useful than it sounds. Charcoal powder needs paper with enough tooth to hold loose dust and enough surface strength to survive being rubbed and lifted again and again. A charcoal pencil that is too hard won’t lift with an eraser; one that is too soft won’t hold a crisp final accent. A student copying his method with different materials can get very different results and wrongly decide they can’t draw. Naming the tools removes that trap.
One Still Life, From First Line to Signature
Go back to the skull on the easel. The reference stays in view the whole time, on a tablet propped beside the drawing, so the drawing is always being compared with something real. That comparing is the easiest part of drawing to hide, and in his lessons it is the point.
The first lines are faint and few — just enough to place the skull, the two apples, the cloth and the brush on the plank. Then come the darkest accents: the eye sockets, the gap under the cheekbone, the shadow beneath the apples. With those fixed, he builds the big dark shapes of the whole group broadly, without stopping to finish any one object.
Only once the arrangement holds together does he move to surfaces. The apples get their roundness, the cloth its folds, the brush its bristles. The background goes in with long vertical hatching, darker behind the skull’s lit side so the white of the bone pushes forward. The edges of each object are not drawn first and shaded afterwards; they appear inside the tone, where light meets shadow.
In the last stage he works over the whole sheet, adjusting tones until everything sits together. The finished drawing is signed in the lower left corner: a skull, two apples, a brush and a cloth, all in shades of gray, and all clearly sitting on the same table under the same light.
Geometry First
Under every still life sit the simple forms, and he teaches them with the same care — cubes, cylinders, a many-sided block of pentagons, crosses and stars of intersecting blocks. For a plaster sphere he draws the circle, then goes straight to the band where light turns into shadow. The cast shadow goes in next, then the half-tones, and finally hatching in the background around the light side, so the sphere reads as white without any white being added.
For a hexagonal prism he works plane by plane. Light construction lines first. Then the darkest face and the cast shadow, in dense hatching. Then the background around it, and only then the middle planes, each a step lighter. The top face is left almost bare paper. Every plane gets one clear value, and the form appears from the differences between them.
The Things on His Table
His still lifes are the exam canon with the difficulty turned up. An apple with three deep dents in it. An apple drawn as if made of clear glass. A bell pepper, a tangerine still on its leafy twig, a baseball cap, a teapot with a woven handle. A woven bag of interlaced strips that have to shrink correctly around its curves. A Coca-Cola bottle that is glass, liquid, label and reflection at once. Pottery jars, a metal mug, bananas and a knife on a draped cloth, and a 人参果 — a ginseng fruit moulded into the shape of a human face.
He also sets himself a full still-life group, from blank paper to finish, in a hundred and fifty minutes — the kind of time limit an exam gives. Finishing is the skill students rarely practise. Over two and a half hours the light moves, charcoal smears under the drawing hand, attention fades, and every relationship — is the jar darker than the cloth, is the mug taller than the fruit — has to be held in mind to the end.
Why Did You Choose Art?
Over one of his drawings of a writing brush, worked in charcoal until the hairs separate at the tip and the metal ferrule catches the light, he asked his students a simple question: 你当初是因为什么选择学美术的？ — what made you choose to study art in the first place?
He didn’t answer it for them. Some of his students have drawn since they were small and could not be talked out of it. Others chose the art route because it opened a door to a school that their other subjects would not. Both sit in the same studio, drawing the same apples against the same clock. Asking the question treats them all as people rather than as exam candidates.
And it fits the way he works. Whatever brought a student to the easel, the brush is the thing they will now spend their days with, and it deserves to be looked at closely enough to draw — hair by ragged hair.
