Chinese Narrative River Poster

Goal: Create a vertical Chinese literary metaphor concept poster about a river made of written language, titled main_title. The image should feel like a high-resolution ink-wash editorial poster, poetic, solemn, and philosophical. Canvas: Portrait 3:4 composition, muted gray-green rice-paper background with subtle grain, stains, and aged print texture. Monochrome black ink and misty gray tones, no bright colors. Layout: Place the large distressed Chinese title at the top center, with bold rough woodblock-print texture. Directly below it, set the centered subtitle subtitle_text. Around the upper and middle margins, add exactly 5 small poetic text blocks: 1 at upper left, 1 at upper right, 1 at lower left, 1 at middle right, and 1 at lower right, each in delicate vertical-feeling Chinese typography with a short horizontal divider line beneath or above. Scene: A vast traditional Chinese ink landscape fills the poster: towering dark cliffs on both sides, distant layered mountains fading into fog, a pale sun near the horizon, scattered pine trees, a tiny pavilion or house on a cliff, birds flying in a small flock, and thick mist drifting through the valley. A wide serpentine river flows from the far distance down to the foreground in an S-curve. Central metaphor: The river surface is not water; it is densely composed of countless Chinese characters, punctuation marks, and fragments of prose. The characters should follow the river current, becoming tiny and dense in the distance and huge, bold, broken, and scattered in the foreground. Make the typography look like it is flowing, eroding, and dissolving like sediment. Include larger readable words embedded in the river such as foreground_keywords. Add splashes and ink debris made of loose characters along the riverbanks. Human element: In the middle-lower river, place exactly 1 tiny lone boat with exactly 1 seated figure holding an oar, silhouetted in black, emphasizing scale and solitude. Small text blocks: Use these 5 visible poetic captions, arranged as described: upper left default text upper_left_caption; upper right text reads “所有的故事\n终将汇入一条河，\n而河流从不忘记\n它走过的每一个字。”; lower left text reads “有些字沉下去，\n有些字浮起来，\n而时间始终向前，\n像一条不回头的河。”; middle right text reads “一条河\n流过无数人的沉默，\n也流过我们\n共同的生存。”; lower right text reads “故事未完，\n河流仍在。” Visual style: Chinese shan shui landscape mixed with contemporary typographic poster design, lithograph and screen-print texture, distressed ink edges, layered fog, high detail, cinematic depth, balanced negative space, crisp legible title, naturally integrated Chinese characters in the river. Constraints: Use exactly 1 main title, 1 subtitle, 5 small caption blocks, 1 boat, and 1 person. Keep the design vertical, elegant, and poster-like. Do not add logos, watermarks, borders, modern buildings, color gradients, or extra Latin text.
