Lee Sun-hee (born 1964) is the legendary Korean singer often called the "National Voice of Korea."
Used widely across Korea.
Sun-hee 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 Sun-hee reduce to 9, The Giver. This is a traditional interpretive system, not a factual claim about the name.
