辉（hui）
Name meaning
辉 (hui) means radiance and reflected brilliance. In names it is confident, bright and familiar, often suggesting honor that shines outward.
Practical naming use
辉 (hui) is a strong light character with a warmer, reflected quality than 光 (Guang). It can suggest moonlight, honor, talent or a person's ability to brighten their surroundings. Because it is familiar in Chinese names, the use needs to stay specific: radiance should become character, learning or public usefulness, not just shine.
Pair 辉 (hui) with culture, clarity or sincerity: 辉文 (Huiwen), 辉明 (Huiming), 辉诚 (Huicheng) or 辉远 (Huiyuan). Avoid stacking too many light characters together.
辉文 (Huiwen): Hui contributes radiance, brilliance; Wen adds culture, writing.
