《文心雕龙·颂赞》
到楚国三闾大夫屈原作《橘颂》情感和文采都很美好，用类似的物作比，寄托自己的情意，颂又推广到细小的物品上了。
及三闾《橘颂》，情采芬芳，比类寓意，乃覃及细物矣。
From the third house doctor of Chu State, Qu Yuan made the "Orange Song", which is very beautiful in emotion and style, using similar things as analogies,寄托ing his own affection, and the song extended to small objects.
