rendered in Chinese ink brush calligraphy style. Letterforms painted with a fully loaded sumi ink brush — deep black ink, visible bristle marks along stroke edges, wet ink pooling at stroke starts, feathered dry-brush trailing ends. Authentic ink density variation: thick rich black cores fading to grey at thin passages. Rice paper texture visible behind. Traditional Chinese calligraphy energy — each stroke confident, intentional, irreversible. LETTERFORM PRIORITY: when the chosen font carries its own treatment, that font's letterform shapes take priority and own the letters; this style governs the sumi ink medium, the bristle and ink-density behavior and the rice-paper ground. FALLBACK MATERIAL: if the font carries no material of its own, render the letters as deep black sumi brush strokes with visible bristle marks, wet ink pooling at stroke starts and feathered dry-brush trails on rice paper. COLOR PRIORITY: keep the font's own colors if specified; otherwise rich black ink fading to grey at thin passages. Create a refined traditional Chinese calligraphy artwork featuring exactly the four characters “劉永生堂,” arranged in a single vertical column, read top to bottom. Give the characters a clear, generous scale and place the column slightly right of center, with ample luminous negative space around it. Set the composition on warm ivory xuan paper, its delicate fibers and softly uneven handmade surface visible throughout. Let confident brush marks carry rich black ink, with expressive shifts from wet, dense pools at stroke beginnings to lighter grey, bristled dry trails at the ends; allow thin passages to reveal the paper beneath. Keep the ink variation organic and distinct, with a restrained, natural feathering into the paper rather than clean, uniform edges. Add a faint, atmospheric ink wash behind the lower portion of the column, soft enough to support the writing without obscuring any character. Place one small vermilion seal impression near the lower right as a quiet accent, separate from the requested text and not legible as additional lettering. The overall piece should feel balanced, contemplative, and complete, with the brushwork as the sole focal point.
