Mei-ling (美齡) combines the Chinese měi (beautiful) and líng (jade tinkle, age). Soong Mei-ling (1898-2003) — "Madame Chiang Kai-shek" — was the First Lady of the Republic of China for over four decades. The first Chinese national to address the U.S. Congress (1943) in fluent English, she became the international face of China during WWII.
Lived to 105.
Mei-ling 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 Mei-ling reduce to 6, The Nurturer. This is a traditional interpretive system, not a factual claim about the name.
