《新唐书·列传·卷五》
承乾还派宫奴数十上百人学习音乐歌曲，学胡人模样梳椎形发髻，剪裁彩绸做舞衣，爬竿舞剑，击鼓声日夜不停。
又使户奴数十百人习音声，学胡人椎髻，剪彩为舞衣，寻橦跳剑，鼓鞞声通昼夜不绝。
Chengqian also sent dozens or hundreds of palace slaves to learn music and songs, and to dress up like the "Hu" people, combing their hair into a comb-shaped hair bun, cutting colorful silk to make dance clothes and climbing poles while dancing swords, the drums never ceasing day and night.
