Xiaowei is from the Chinese 小薇 (Xiǎowēi — xiǎo small/little + wēi rose-mallow/great — little rose-mallow, small but great). Xiaowei is one of the Chinese feminine names — central to traditional Chinese Confucian heritage.
Xiaowei does not currently appear in the US Social Security Administration's top 1,000 girls' names, so we don't publish a US rank or birth count for it. That says nothing about the name's standing elsewhere in the world — only that it sits outside the ranked US data we rely on.

In Pythagorean numerology the letters of Xiaowei reduce to 5, The Seeker. This is a traditional interpretive system, not a factual claim about the name.
