《淮南子·齐俗训》
北方的胡貉和匈奴，衣服胡乱缠裹，披头散发，又是席地叉腿而坐，说话叽哩呱啦，但国家不会灭亡，这是因为我们看似无礼，实质他们有他们的礼节。
胡、貉、匈奴之国，纵体拖发，箕倨反言，而国不亡者，未必无礼也。
The Hu and Huns in the north wear their clothes haphazardly, disheveled and unkempt, and sit on the ground with their legs crossed, speaking gibberish, but their country will not perish, because although we seem to be rude, they actually have their own etiquette.
