This essay is to examine the commonly accepted view of the prohibition on Hu-style(Xianbei-style) garments in A.D. 494, which banned Xianbei-based nomadic or pastoral people from wearing Hu-style(Xianbei-style) dresses and hats. I overturned conventional wisdom of the prohibition on Hu-style(Xianbei-style) garments in 494, which was not observed thoroughly. I set forth evidence that after the ban of the emperor Xiaowen in A.D. 494 Xianbei people wore their traditional Hu-style(Xianbei-style) dresses and hats. In this essay, I examine the dress and hat of the pottery figurines in excavated in tombs of Northern Wei period in Beimang Mountain, which is located in north of Luoyang, the capital of Northern Wei period. If the dresses and hats of the pottery figurines in excavated in tombs of Northern Wei period was reflected to that of Luoyang residents, ratio of Hu-style(Xianbei-style) dresses and hats is 13.9%(or 10.8%), but that of Han(Chinese)-style garments and Western Region-style garments is 18.6% and 8.3% respectively. The mixture of Hu-style(Xianbei-style) and Han(Chinese)-style garments is 46.7%(or 49.8%). This showed that after the ban of the Xianbei-style garments, Hu-style(Xianbei-style) dresses and hats were dressed both Xianbei-based nomadic or pastoral people and Chinese, Xianbei and Chinese costumes were mixed and influenced mutually. I don`t deny the fact that there was Xianbei people to wear Chinese costumes but it was applied in their public lives and they wore Xianbei costumes in daily lives. I brought forward a reason to break partly the emperor Xiaowen`s ban on weaing Hu-style(Xianbei-style) dresses and hats that there was the decrease drop in temperature in period of Nanbeichao(Northern and Southern Dynasties) why Luoyang residents wore the Hu-style(Xianbei-style) dresses and hats, which was better to protect them from the cold.
