PRODUCTION REVISION: Use crisp deliberate print strokes and bounded flat colours, not a textured low-resolution painting. No fuzzy contour, photographic shading, painterly haze or opaque landscape panel. All exterior and interior empty space is transparent alpha zero. Keep all letterforms and complete objects inside x100..3740 and y120..1160 on the native canvas. Render the main region title clearly; if a tiny caption would be unreadable, omit that caption rather than duplicate or distort it. The white surface in the reference is a viewing aid and must not be drawn.

Create one exceptional, completely flat regional ceramic-print artwork. This is the actual printable illustration, never a cup, product photograph, mockup, presentation board or simulated ceramic surface. The collection reference controls drawing language only: invent a new composition for the specified region and replace all Guangdong-specific objects. The source map supplies a regional inventory, not a paper texture or a layout to trace literally.

TECHNICAL CONTRACT: native canvas exactly 3840 x 1280 pixels, true RGBA PNG. Keep every visible mark, letter, ornament and antialiased edge inside x=60..3780 and y=110..1170. The final delivery will use a centered 3840 x 1152 export for a 250 x 75 mm wrap; leave the native safety area completely transparent. Compose for a long horizontal physical print, not a conventional poster. Nothing is cut off at either end. All exterior space and meaningful holes between objects must have alpha zero. No painted background, white underpainting, sky rectangle, tinted paper, land silhouette, colour fog, opaque backdrop or checkerboard. The wearer-visible ceramic supplies the unprinted space. Use the specified colours as ink, with normal edge antialiasing; do not invent extra white, black or metallic ink. Never print dimensions, crop marks, palette swatches, filenames, reference names or instructions.

ART DIRECTION: create a memorable hierarchy, a major focal scene and a quieter counterweight; alternate large close forms with medium stories and a few small discoveries. Let tea life interact with the region. Connect selected objects through a real roofline, tabletop, lane, ridge or river contour; retain clear breathing channels so each gesture and vessel is legible. Do not impose any percentage of empty space. Avoid both a cramped rectangular carpet and timid isolated stickers. Use confident, intentional linework that will survive the 75 mm print height. Limit texture to useful material clues. Any water, snow, steam or clouds are sparse outlines with transparent interiors, never washed fills. No photographic gradients, glow, heavy grunge, blurred edges or tiny illegible hatch fields.

FACTUAL DISCIPLINE: the scenes below distinguish cultivation, processing, trade, hospitality and non-tea infusions. Do not turn imported tea, berries, ginseng, barley, trees or grasslands into tea plantations. Do not invent a local tea cultivar, a named historic tea shop, medical effects, a precise trade route or archaeological evidence. Landmarks are cultural/geographic motifs, not assertions that tea was grown or traded at their gates. A contemporary tea pause next to a landmark is an authored scene, not a documentary historical claim. Keep people natural and respectful, with plausible hands and gestures; use no decorative pseudo-script.


C4: INTIMATE DRAWN REGIONAL ATLAS. Use the Guangdong garden-atlas reference as a collector-illustration benchmark: fine lively contours, locally observed architecture, nature, animals and tea. Three inks, selected wood, stone and textile marks; delicate tall serif regional title nestled among roofs or ridges. Two unequal scenic anchors and smaller discoveries share a curved geographic backbone. Draw a believable regional journey, not a dense medieval engraving or a diagram of isolated objects.

REGION: Gansu. Exact ink palette: #564238, #B97D2E, #428A99. The first colour supplies the main line; the others have deliberate separate roles, not gradients.

AUTHENTIC SUBJECT MATTER:
Gansu is an extraordinary transition from desert corridor to humid southern mountains. Include a compact Jiayuguan gate and short crenellated wall, two Bactrian camels with a guide, a crescent spring and sparse oasis tree, a few striped Zhangye Danxia ridges, the angular Qilian skyline, and the curved steel-truss bridge across the Yellow River at Lanzhou. Counterweight these dry northern forms with the wooded Longnan tea valley. Add a small Maijishan cliff facade, a modest Labrang roof group, and one yak near a pastoral tent. Use these as recognizable geographic objects at deliberately unequal sizes, not every monument as a giant equal hero. Mogao may be suggested by a small arched cave entrance rather than a large sacred portrait. No painted desert or river fill. Tea appears through actual people and vessels, integrated into the journey.

Tea anchors that remain visible: Wenxian green-tea picking, a Sanpaotai gaiwan with a pouring hand, Tianshui clay-pot tea on a stove, and a small Gannan butter-tea bowl/churn; the first is cultivation, the others are drinking customs.

SPECIFIC COMPOSITION:
Build an S-shaped collector journey whose large left anchor is the Jiayuguan gate with two camels passing below, while the larger right anchor is a humid Wenxian tea-picking hillside. Between them the spring crescent, striped Danxia and Qilian ridge diminish to far distance. The Lanzhou bridge enters as a medium low arch toward the viewer; a Sanpaotai table touches its riverbank contour. A Gannan yak, tent and small Labrang roofs make a compact upper-right counterpoint. Tuck Maijishan into a gap below the skyline as an architectural cliff detail. Place GANSU in elegant narrow serif letters above the bridge, not in a blank header. Leave sky and river openings wholly transparent.

VISIBLE TYPE: exact main title "GANSU" once. The regional title is the only printed text. Do not add small location labels. No Chinese characters, bilingual captions, pseudo-calligraphy, gibberish, slogans, logos or signatures. Prioritize visual storytelling over words. Do not allow letters to merge with foliage or buildings. The design must feel like a collectible regional artwork that a tea professional would want to handle and study.
