U+53E4 "古" CJK Unified Ideograph-# Unicode Character
Unicode Version 17.0
古
U+53E4 "古" CJK Unified Ideograph-# is a Chinese character that represents the concept of "old," "ancient," or "antiquity," and is commonly used in East Asian languages including Chinese, Japanese, and Korean. Its visual composition combines the radical for "ten" or "complete" with a component suggesting a mouth or enclosure, often interpreted as the idea of passing down stories or traditions across many generations. In modern usage, this ideograph appears frequently in words related to history, archaeology, and traditional culture, such as 古代 (ancient times) or 古典 (classical), and it carries a sense of timeworn wisdom and enduring legacy.
