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 finished traditional calligraphy artwork featuring the exact four characters “真心待人,” arranged vertically in one commanding column, read from top to bottom. Let the characters occupy most of the central height, with generous breathing room around the column and a little more open space above and below. Make the first two characters slightly larger and visually weightier, while keeping the full phrase balanced and easy to read. Set the work on warm ivory xuan paper, its fine fibers and natural grain visible across the quiet background. Preserve expressive wet-to-dry variation within every brushstroke: dense, glossy black pools at forceful beginnings, rich ink through the central passages, and broken gray bristle trails tapering into luminous paper. Allow subtle feathering where wet ink meets the paper, with only a few restrained ink flecks near the most energetic strokes. Behind the characters, add a faint, uneven gray ink wash that dissolves softly into the untouched paper without reducing legibility. Place one small vermilion seal impression near the lower edge, off to the side of the calligraphy, as a discreet finishing accent. Keep the composition contemplative, assured, and uncluttered.
