Chuānghuā (window flower) is a traditional Chinese folk art form consisting of intricately cut paper designs, typically pasted on windows during festivals—especially Spring Festival—to bring good luck and festive cheer. The character 窗 (chuāng) means 'window', and 花 (huā) means 'flower', but together they refer not to actual flowers, but to decorative patterns—often featuring flowers, animals, auspicious symbols, or scenes from folklore—that resemble blossoms in their delicate, symmetrical beauty.

These paper-cuttings are usually made from red paper, symbolizing joy and prosperity, and are hand-cut with scissors or knives. Though 'flower' appears in the name, chuānghuā designs frequently depict birds, fish, dragons, or characters like 福 (fú, 'good fortune'). They’re deeply rooted in northern Chinese rural culture but are now appreciated nationwide as intangible cultural heritage and seasonal decorations.
