Transcription of Qianlong emperor's Imperial "Painting of Inspecting Horses by the Yangximu [River] Song"

成扇

坰人校所司。日下駐金支。忽變雲為谷。爭傳種是獅。秋風鳴處勁。電影驟時追。獨憶詩人詠。奚官總未知。閱馬。肥壤挾川河。名駒恣寢訛。魯詩空賦駉。唐牧漫誇多。比色猶鋪錦。分馳似捲波。太平無戰伐。憑眺意如何。閱馬。坰場亘瀋野。芻牧接遼濆。養息良駒盛。調閑眾圉分。三千突騋牝。五色耀卿雲。驟似波鋪地。看如錦叠紋。無邪思古訓。斯作喜今羣。敢忘馳驅際。用兹佐六軍。養息牧閱馬。御製詠馬詩。臣彭元瑞敬書。
