What is the content of Cao Cao's poem "Gui Si Shou"?

Although turtles live long?

Han dynasty? Cao Cao?

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

The snake rides the fog and eventually turns to dust.

An old horse crouches, aiming at a thousand 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.

Guithough Shou is a four-character Yuefu poem by Cao Cao, a writer and politician in the Eastern Han Dynasty. This poem is the fourth in the series "Out of Xiamen". The author compares himself to an old galloping horse. Although he is old and weak, he has been relegated to a lower position, but his chest is still full of lofty sentiments and ambitions, showing a positive attitude towards life, full of real experience of life, and has sincere and strong emotional strength.

The whole poem combines poetic sentiment and philosophy, with ingenious conception, clear and vigorous language, philosophical thinking and impassioned, and artistic image, which realizes the perfect combination of reason, ambition and emotion in concrete artistic image.
