A poem describing the realm of literati

Although the tortoise has a long life, it still has its time.

A poisonous snake flew in the fog and was finally covered with 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.

Fortunately, even! Sing with ambition.
