Create a 9:16 ultra-long vertical educational infographic introducing the chronological progression of Chinese dynasties. Include the full dynasty sequence as completely as possible, from the earliest dynasties through Xia, Shang, Zhou, Qin, Han, Three Kingdoms, Jin, Southern and Northern Dynasties, Sui, Tang, Five Dynasties and Ten Kingdoms, Song, Yuan, Ming, Qing, and later historical transition context where appropriate. Use a clear central timeline with stacked era sections, dynasty name labels, date ranges, branching parallel periods when needed, small symbolic palace, artifact, landscape, scholar, soldier, and map icons, restrained traditional Chinese patterns, and a warm parchment, ink, cinnabar, jade green, blue, and gold palette. Keep the layout structured, educational, balanced, and suitable for public learning material, with legible hierarchy and clean spacing. Avoid missing major dynasties, random modern symbols unrelated to the timeline, political persuasion, caricatured history, messy typography, unreadable microtext, watermarks, logos, and low-resolution artifacts.
