It is said that, in those days when there was only one copy of "Bai-Shi Wen Ji" (a collection of poem by Bai Letian, a famous Chinese poet) in Japan, when the emperor showed that book to Takamura after changing a character in a poem written by Bai Letian for fun, Takamura returned the book after correcting the character modified by the emperor.
まだ日本に『白氏文集』が一冊しか渡来していない頃、天皇が戯れに白楽天の詩の一文字を変えて篁に示したところ、篁は改変したその一文字のみを添削して返したという。
