Is it a poem that an old horse crouches and aims at a thousand miles?

This is a poem. From the fourth time of Cao Cao's Yuefu poem "Out of the Summer Gate"-"Although I return to my life". The whole poem is as follows:

Although the tortoise has a long life, it still has its time. The snake rides the fog and eventually turns to dust.

The old horse crouches, aiming at thousands of miles; The martyrs were full of courage in their later years.

The surplus and contraction period is not only in the sky; Blessings that nourish grace can last forever.

I am glad to use this poem to express my inner desire.
