Xunzi said in the chapter "Cultivation of the Body": "The body is respectful but the heart is loyal, the etiquette is righteous and the heart is loving, and it is rampant in the world. Although it is trapped in the barbarians, all people are noble." What he means is that the heart is pure. A person who is respectful, loyal, and loves others sincerely according to etiquette can travel all over the world. Even if he is in a barbaric land, people will still respect him.
