Huaya ("flower seal"; Chinese: 花押; pinyin: Huā Yā; Korean: 화압, romanized: Hwaap; Japanese: 花押, romanized: Kaō, Vietnamese: hoa áp, chữ Hán: 花押) are stylized signatures or marks used in East Asian cultures in place of a true signature. Originating from China, the huaya was historically used by prominent figures such as government officials, monks, artists, and craftsmen. The use of stamp seals gradually replaced the huaya, though they are still used occasionally in modern times by important people.
