Daoyun (道韞, c. 340-c. 410) was the Eastern Jin Dynasty poet — niece of the famous Prime Minister Xie An. At a family snowfall gathering, when her uncle asked the assembled children what the falling snow looked like, she famously answered: "It is like willow catkins lifted in the wind" — a metaphor that became the canonical literary image and earned her the nickname "Mistress of Snow." Featured in the Shishuo Xinyu (5th c.) and beloved as a model of female literary wit.

Daoyun 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 Daoyun reduce to 8, The Visionary. This is a traditional interpretive system, not a factual claim about the name.
