百（bai）
Name meaning
百 (bai) means hundred, many and broad abundance. In a name it should suggest breadth and gathered capacity, not a bare number.
Practical naming use
Use 百 (bai) when the name should feel broad, abundant and capable of holding many things together. It suits education, research, commerce, diplomacy, design, public service or any image where range and accumulation matter. The character needs a second character with clear human direction, because by itself it can sound numeric rather than personal.
Pair 百 (bai) with 明 (ming) for broad clarity, 文 (wen) for many-sided learning, 安 (an) for settled abundance, or 雅 (ya) for refined breadth. Avoid a second character that also means many or large, because the name can become slogan-like.
百明 (Baiming): Bai contributes hundred, abundance; Ming adds brightness, clarity.

Use notes
Use carefully; can feel numeric if paired poorly.
