From
李商隐 (Li Shangyin, Tang, 9th c.), a poem praising the ten-year-old prodigy
韩偓 (Han Wo):
十岁裁诗走马成,
桐花万里丹山路,
雏凤清于老凤声 (the young phoenix's song is clearer than the old phoenix's). Phoenixes nest in paulownia trees and dwell on Cinnabar Mountain in Chinese mythology, so the line maps out the glorious path ahead of the young Han Wo.
