Create a 16:9 educational literary poster inspired by Du Fu's classical poem "Song of the Thatched Cottage Destroyed by Autumn Wind". Use a horizontal composition: the upper band contains selected large Chinese calligraphy lines from the poem with small Hanyu Pinyin above each character, while the lower and middle area becomes a dramatic Chinese ink-and-wash illustration. Show a storm-dark autumn sky, slanting rain, wind-torn reeds and bamboo, and a poor thatched cottage with its roof damaged by the gale. The mood should feel solemn, humane, and poetic, with cream paper texture, black ink calligraphy, blue-gray watercolor washes, and restrained classical scholar-painting atmosphere. Keep the Chinese text clear, aligned, and poster-like, but treat it as selected excerpt text rather than the full poem. Avoid modern logos, creator handles, unrelated captions, fake signatures, or decorative text outside the poem and pinyin.
