《汉书·志·礼乐志》
纷纷树立的羽葆像树林一样，像云影一样高远难见，黄金装饰的乐器羽葆，像草木一样华秀，像用旎牛尾和翠羽装饰的旌旗一样漂亮。
芬树羽林，云景杳冥，金支秀华，庶旄翠旌。
The colorful feather feathers are like forests, and they are as far away as clouds and shadows. The feather feathers of the golden musical instruments are as gorgeous as plants and trees, and as beautiful as the flags decorated with yak tails and green feathers.
