Kalligrafiemanuscript

Create an authentic-looking handwritten Chinese calligraphy manuscript of the classic text or passage described in the user request, rendered as if brushed by the author's own hand in the moment of writing. Present it on aged xuan paper in a warm ivory tone with subtle fiber texture, faint foxing spots, and softly worn edges, photographed flat under gentle diffuse light. Brush the characters in expressive ink calligraphy whose rhythm embodies the emotional core of the work: let stroke weight, speed, spacing, and occasional flying-white dry-brush passages rise and fall with the feeling of the words — serene and measured for contemplative lines, loose and urgent cursive for grief or passion. Arrange vertical columns reading right to left with natural size variation, a few emphasized or corrected characters, and one or two vermilion seal stamps placed with a connoisseur's restraint. Ink should show believable gradation from saturated black to soft gray bleed into the paper, and every character must be a real, correctly formed glyph. Keep the frame purely the manuscript page — no hands, desk clutter, watermark, modern typography, or printed-font regularity.
