Literature Reference: 画弦素管声浅繁，花裙綷䌨步秋尘。桂叶刷风桂坠子，青狸哭血寒狐死。古壁彩虬金帖尾，雨工骑入秋潭水。—— 《相和歌辞 神弦曲》 李贺 Strings and pipes play soft and varied tunes, as flowered skirts tread the autumn dust. Cassia leaves brush the wind, and cassia seeds fall, while green foxes weep blood and cold foxes die. On ancient walls, colorful dragons with gold-tipped tails, as rain workers ride into the autumn pool. Source from 'Xianghe Ge Ci Shen Xian Qu' by Li He.
