紫色の玉（ぎょく）で作られた優美なる龍笛。
琵琶と並び楊貴妃の愛用していた楽器のひとつ。
月の仙女“嫦娥”より楊貴妃に贈られた品と伝わる。

「この一本の笛をふたりで一緒に吹いてみたり……
　そんな戯れもまた愉しげな調べとなるものです」

An elegant flute made from purple jade.
It is one of the instruments that Yang Guifei was versed in playing, along with the pipa.
It is said that the instrument was gifted to her by the Chinese goddess of the moon, Chang'e.

"The two of us trying to play this single flute together...even a playful attempt like that surely will yield a melodic tune."
