Princess Pingyang (平陽, c. 600-623) — daughter of Li Yuan, founder of the Tang Dynasty — *personally raised and commanded the Niangzijun ("Army of the Lady") of 70,000 troops during the founding of the Tang. She held the strategic Niangzi Pass that bears her army's name — the only pass in the Great Wall named after a woman. Died young at 23; honored with a full military funeral by her father — the first time in Chinese history a princess received one*.
Featured in Tang dynastic histories.
Pingyang 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 Pingyang reduce to 3, The Communicator. This is a traditional interpretive system, not a factual claim about the name.
