U+6613 "易" CJK Unified Ideograph-# Unicode Character
U+6613 "易" CJK Unified Ideograph-# is a foundational Chinese character with rich historical and philosophical significance, primarily denoting "change," "easy," or "exchange." Its earliest attested form appears in oracle bone script from the Shang dynasty, where it was used in divination contexts. Over time, the character became central to Chinese thought through its association with the "I Ching" (or "Book of Changes," Yijing), one of the oldest and most influential classics of Chinese philosophy, which explores the constant transformations underlying reality. Beyond philosophy, "易" is commonly used in modern Chinese to indicate simplicity (as in "容易" meaning easy) or transactional concepts (such as "交易" meaning trade or exchange), illustrating its evolution from a divinatory symbol to a versatile and enduring element of the written language.
