Bao (寶) is the Mandarin Chinese word for "treasure" or "precious." Used in compound names (Baozhu "precious pearl") and as a term of endearment.
Bao Tong (1932-2022) was the Chinese reformist political figure.
Bao 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 Bao reduce to 9, The Giver. This is a traditional interpretive system, not a factual claim about the name.
