U+6731 "朱" CJK Unified Ideograph-# Unicode Character
Unicode Version 18.0
Source: Browser Default
U+6731 "朱" CJK Unified Ideograph-# is a Chinese character that primarily means "vermilion" or "bright red," historically derived from the color of the cinnabar pigment used in ancient China. It also serves as a common surname in Chinese culture, famously held by figures such as the Ming dynasty founder Zhu Yuanzhang. In classical texts, "朱" can denote the southern direction, associated with the vermilion bird in traditional cosmology, and it appears as a component in compounds like "朱砂" (cinnabar) or "朱门" (literally "vermilion gates," referring to wealthy households). The character's structure combines the tree radical "木" with an additional stroke, reflecting its etymological link to the color of the tree's heartwood or sap.
