2. This poem comes from Cao Cao's "Although a turtle is a longevity", so the answer is Cao Cao.
3. Original text: Although the tortoise has a long life, there is still 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.
