According to Baidu Encyclopedia, "What is a Woman Flower" is a song sung by Situ Lanfang, with lyrics written by violet for snow and music composed by earthly elves.
Lyrics from What Flowers Does a Woman Bloom: A fragrant flower, picturesque. With spring, summer, autumn and winter, quietly reveal the fragrance of Zhenhua. Flowers blooming in my heart are shy. Beauty is charming and flawless. What a beautiful woman she is. Women's flowers, women's flowers, 10 thousand kinds of tenderness for no one can let go. Fragrant petals wither, whose care falls quietly.
