Chinese Red University Anniversary Poster

Goal: Create a grand Chinese red anniversary celebration poster for a university centennial-and-beyond milestone, combining government-style ceremonial design with elegant campus line art. Canvas: Wide horizontal poster, 16:9 ratio, deep China-red background with subtle vignette and glowing gradients. Use a premium red-and-gold palette: crimson, scarlet, dark wine red, warm gold linework, and ivory-gold typography. Layout: Dominant oversized outlined number anniversary_number spans the upper half of the poster, drawn with many thin parallel gold contour lines. Integrate delicate gold architectural line drawings into the number and around it: an open book at the lower left of the 1, a campus clock tower and academic buildings inside the 2, and a ceremonial university gate inside the 0. Across the middle and lower half, create layered flowing red silk waves like a national flag, with luminous highlights and realistic satin folds, partially covering the bottom of the large number. Add small decorative elements in the sky: exactly 7 flying birds in pale gold, and exactly 4 radial firework/starburst ornaments placed around the upper left and upper right areas. Main text: Centered vertically over the silk waves, set large vertical Chinese title text main_title in an elegant Song/Ming-style serif font, ivory-gold with a soft glow. To the left of the title, add a smaller vertical line anniversary_subtitle. To the right of the title, add a small outlined vertical seal-shaped label reading seal_text. Beneath the main title, place a thin rectangular gold-outline date plaque reading date_range. Lower information area: Include exactly 3 event information blocks across the lower third, separated by two thin vertical divider lines. Left block: simple gold outline icon of a classical building, with two lines of Chinese text: “百廿校庆 · 共襄盛典” and “2025年10月18日-20日”. Middle block: simple gold outline icon of celebratory linked circles, with two lines: “全球校庆 · 闻贺华诞” and “线上线下 · 共赴未来”. Right block: simple gold outline play-button icon, with two lines: “云端校庆 · 精彩直播” and “关注官方平台观看”. Along the very bottom center, add widely spaced small gold Chinese values text: “传 承 · 创 新 · 卓 越 · 担 当”. Visual style: High-end official Chinese institutional poster, festive but refined, cinematic lighting, clean symmetrical composition, delicate thin gold lines, realistic red silk texture, no people, no watermark, no extra logos, sharp readable typography.
