This is a passage from a junior high school textbook, Ma Shuo.

There are often swift horses, but Bole is not often. Such a horse, even if it has the ability to travel thousands of miles a day, is short of food and physical strength, and its talent and excellent quality cannot be exerted. If it wants to be as impossible as an ordinary horse, how can it be required to walk thousands of miles a day?

I hope you can adopt it.
