In the Tan dynasty it cultural style was very international and its culture actively absorbed other foreign culture. Moreover it was the time when the concept of barbarians(胡, hu) was applied widely and its culture got the tremendous influence from other foreign culture The influence from the barbarians were tremendous in Tang dynasty so that among the ten elements of the Sipbuak(十部樂) in Tang period only ChungSangAk(淸商樂, Qingshangyue) and YenAk(燕樂, Yenyue) were from their own Chinese culture(漢, Han). I wanted to discuss the influences of the Barbarians cultures on the dancing costumes in Tang period for it appeared to me that especially the dancing costume with the introduction of new foreign dances and their distinct styles in costumes would make a great impact on the dressing styles in Tang dynasty On the dancing costumes in tang dynasty we dan find the strong influences by the Barbarian style(胡風, hufeng), and even the authentic Chinese dressing styles of han period appear to be change quite a bit.
