This poem comes from Fang Bing Cao Xu's Poem written by Du Fu in the Tang Dynasty.
Original text:
Fang Bing's horse is a horse of Dawanguo, and its thin bones are as clear as a blade.
Its ears are as sharp as a piece of bamboo, and it runs like four winds, as if its hoof had not been trampled.
The horse galloped, never in an open way, riding it all very comfortable, dare to roam the battlefield, and even share life and death.
So fast, so fast, it is a good horse that can live up to life. It can commit crimes for the country.
This is a poem that eulogizes things and expresses one's heart. Du Fushan rode horses and loved them. He wrote many poems about horses. The style of this poem is super vigorous and powerful, which embodies the enterprising spirit of young Du Fu.
