Xiaoting is from the Mandarin Chinese xiǎo (小 — small) + tíng (婷 — graceful, slender). Princess Xiaoting — modern Chinese-Korean heritage naming.
Xiaoting 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 Xiaoting reduce to 9, The Giver. This is a traditional interpretive system, not a factual claim about the name.
