U+5366 "卦" CJK Unified Ideograph-# Unicode Character
U+5366 "卦" CJK Unified Ideograph-# is a Chinese character that primarily means "divination symbol" or "trigram," and it holds deep significance in the I Ching (Book of Changes), where it represents one of the eight fundamental trigrams or the sixty-four hexagrams used for philosophical and oracular purposes. This ideograph is composed of the radical 卜 (divination) and the component 圭 (a jade tablet), reflecting its association with ancient Chinese methods of predicting the future and understanding cosmic patterns. Beyond its mystical roots, the character also appears in modern usage to denote categories, situations, or phases in various contexts, such as in the word 八卦 (bāguà), meaning "gossip" or "the eight trigrams," and it remains a key element in East Asian cultural, philosophical, and linguistic traditions.
