Wan'er (婉兒, 664-710) means "graceful child." Shangguan Wan'er was the Tang court poet, stateswoman, and confidante of Wu Zetian — orphaned as a child when her grandfather was executed, she was raised in the palace, rose to become Wu Zetian's secretary, *drafted imperial edicts, and held the title of zhaorong (high-ranking concubine). Her tomb was discovered in 2013 near Xi'an*, with an epitaph detailing her remarkable life.
Subject of the 2014 Chinese TV drama The Glory of Tang Dynasty.
Wan'er 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 Wan'er reduce to 7, The Seeker. This is a traditional interpretive system, not a factual claim about the name.
