Сын Неба
"The Son of Heaven in the land where the sun rises addresses a letter to the Son of Heaven in the land where the sun sets. We hope you are in good health." When the Emperor saw this letter, he was displeased and told the chief official of foreign affairs that this letter from the barbarians was discourteous, and that such a letter should not again be brought to his attention. (tr. Tsunoda 1951:32)
