外論曰。夫華夷禮隔。尊卑著自典墳。邊正道乖。勝負存乎史冊。戎狄之主。不許僭號稱王。楚越之君。故自貶之為子。豈可獯鬻之小匠。匹我天王之大師。此華夷之異四也。

The external treatise says: Ritual separates the Chinese and the barbarians, and high and low are evident in the classic canons. The difference between fringe and central ways, and who prevails or falls, is recorded in the historical annals. The lords of the Rong and Di are not permitted to usurp the title of king; the rulers of Chu and Yue thus demoted themselves to the rank of viscount. How can the petty artisans among the Xiongnu be matched against the great teachers of our Heavenly Kings? This is the fourth distinction between Hua and Yi.
