《资治通鉴·晋纪·晋纪三十四》
只有安国将军勿仑说： 我们国家自从祖先到现在，都习惯于披散头发，左边开衣襟，从来没有帽子腰带之类的装饰，只是追逐选择有水、有草的地方不断迁徙居住，没有城郭家室居所的拖累，所以我们能够在沙漠的各部族中称雄，与中原的汉族人相抗衡。
安国将军鍮勿仑曰： 吾国自上世以来，被发左衽，无冠带之饰，逐水草迁徙，无城郭室庐，故能雄视沙漠，抗衡中夏。
Only General of Pacification Wulun said: our country, from our ancestor down to the present day, has always been accustomed to unbraided hair and left-sided robes, and has never known of such decorations as hats and belts; we have merely sought out places with water and grass, kept moving our abode, without the encumbrance of city walls and family dwellings, and this was what enabled us to stand supreme among the tribes of the desert and rival the Han of Zhongyuan.
