U+588E "墎" CJK Unified Ideograph-# Unicode Character

U+588E "墎" CJK Unified Ideograph-# is a Chinese character that historically refers to an outer wall or a defensive rampart, often used in the context of ancient fortifications to describe a secondary or outer city wall. This character is composed of the radical "土" (earth or ground) on the left, suggesting its association with earthen structures, and the phonetic component "郭" (guō, meaning outer wall or enclosure) on the right, which reinforces its meaning. It is relatively rare in modern usage, appearing mainly in classical texts or historical references to military architecture and urban planning in ancient China.
