โปสเตอร์พู่กันจีนซีอาน

An exquisite Chinese cultural tourism poster with a textured, off-white Xuan paper background and ample whitespace. The composition employs elegant ink wash brushstrokes that meander diagonally from the lower left corner to the upper right, resembling a flowing river of ink. At the far left edge, display 1 traditional Chinese writing brush entering the frame, its tip as if outlining the entire scene. Within the flowing brushstrokes, depict miniature historical landscapes of {argument name="city name" default="Xi'an"}: arrange 3 major architectural landmarks along the curved path, including 1 ancient city gate on the lower left with gray stone walls, arched entrance, battlements, and a double-eave hip roof; 1 magnificent traditional pavilion or palace in the middle with green tiles, red wooden beams, a high platform, and steps; and 1 towering brick pagoda on the upper right standing on a stepped base, surrounded by sparse trees. Interweave a narrow turquoise river or canal throughout the scene, complemented by earthy tones, scattered rocks, winding paths, small shrubs, and scattered soft autumn leaves. The entire landmark miniature presents a texture combining a handmade 3D miniature model with Chinese ink painting and relief art, with delicate ink splatters along the edges of the brushstrokes. Below the ink wash scene on the lower left, place 1 prominent line of bold black calligraphy “Xi'an”. Below that, include 2 neat lines of Chinese characters: “Spring breeze favors swift horses, see all the flowers of Chang'an in a day” and “Thirteen Dynasties Ancient Capital · Starting Point of the Silk Road”. Add 1 red seal near the text. Overall style: poetic, high-end, museum-quality city promotional artwork, Chinese traditional aesthetics, soft warm light, high detail, balanced composition, vertical poster layout.
