Spring Tsing Hua Arts Festival Poster Design

Create a split-screen graphic design poster for the '2025 Spring x Tsing Hua Arts Festival'. The left side features a clean white background with vibrant, flat vector-style illustrations of flowers including a large daisy, pink lilies, blue hydrangeas, and purple lilacs. Vertical Chinese text on the far left reads '2025 春之清華藝術節' alongside English text 'Spring x Tsing Hua Arts Festival'. The bottom left contains four distinct event categories: '音樂會暨大師班', '創作展覽', '藝術工作坊', and '研討論壇', each with specific dates (4/15-5/28) and small QR codes. The right side displays a soft-focus, dreamy version of the same floral arrangement against a warm, hazy cream background. Large serif typography at the top reads '2025 Spring x Tsing Hua Arts Festival', accompanied by smaller text 'ART CULTURE PEOPLE IN BLOOM'. The bottom right shows the dates '4.15 — 5.28' and the logo 'TSING HUA UNIVERSITY'.
