Create a minimalist new-Chinese aesthetic poster in 9:16. Use an elegant pale gray-white background with a three-dimensional paper-cut silhouette feeling. An S-shaped winding torn-paper edge divides the composition, as if one paper layer has been peeled open to reveal a colorful Eastern landscape inside. Within the opening, a winding river flows from top to bottom through the whole composition, rendered in layered blues like a flowing silk ribbon. Place lush hills and terraced fields along both riverbanks, using soft greens and reds to show quiet pastoral beauty. Arrange ancient-style buildings along the river with staggered placement, upturned eaves, white walls, and dark tiled roofs, looking simple and elegant under light and shadow. Add leafy trees on the banks and a small boat resting quietly in the water. The overall composition follows an S-shaped curve with rhythm, suggesting harmony between nature and culture. Use torn-paper edges to create a relief-like dimensional visual experience. At the bottom, write “东方美学” in black kaishu-style calligraphy, include the date “2026/04/18” with a red seal, place the word “CHINA” prominently, and finish with a subtle signature “@LIYUE”. The atmosphere should be quiet, deep, poetic, and contemplative.
