In May of the 12th year of Jian 'an, Emperor Xian of Han Dynasty, Cao Cao defeated Yuan Shao in the battle of Guandu. Since then, the military strength has been greatly enhanced, and Cao Cao has become more ambitious. In July of this year, Cao Cao led his army out of Lulong Village with the ambition of unifying the north, and made an expedition to Wuhuan day and night. When the army arrived in Liucheng, it defeated the Wuhuan cavalry and killed Khan Tatun. Yuan Shang and Yuan Yuan, the sons of Yuan Shao, fled from Liucheng to Gongsun Kang, Pingzhou. When Cao Cao's generals learned of this incident, they suggested that Cao Cao attack with 56 victories, take Pingzhou and destroy the Yuan brothers. Cao Cao knew that Gongsun Kang and Er Yuan were at odds. If they were in a hurry to attack Pingzhou, they would definitely join forces to resist. If we wait a little longer, they will kill each other. So he ignored the generals' advice and ordered to retreat. A few days later, Gongsun Kang sent Yuan's brother's head. In this way, Cao Cao's northern expedition to Wuhuan and the great cause of unifying the north was completed.
Just after the Mid-Autumn Festival, Cao Cao ordered the team to return to the DPRK. After more than ten days of arduous trekking, the army finally walked out of the desolate Liucheng and came to Changli, Hebei. There is Jieshi in the east and the sea in the west. Cao Cao stood on the top of the mountain overlooking the sea. At this time, the sun sets, blue sea and golden light; The islands in the distance are looming, and the waves in the vicinity are rolling forward. Seeing such a magnificent scenery, Cao Cao couldn't help but feel poetic again and blurted out:
See the sea
On the east coast, climb Jieshi Mountain to see the vast sea.
The sea is so vast that the islands stand high on the sea.
Trees and paraquat are very lush. Autumn wind makes trees make sad sounds, and the sea is surging.
The movement of the sun and the moon seems to come from the vast ocean.
Journey to the sun and the moon, if you go out.
Han is a talented star, if you take him by surprise.
I am glad to use this poem to express my inner desire.
After returning to the barracks, Cao Cao was still ups and downs and could not be calm for a long time. He thought: Although Yuan Shao and Ta Dun in the north have made peace, Sun Quan and Liu Biao in the south are still on the side. The great cause of the motherland's reunification has not yet been realized. At this time, Cao Cao is 53 years old, but the important task of history is on his shoulders, and the mission of reunifying the motherland is still calling him. Thinking of his passion and lofty sentiments, he strode to the front of the case and wrote:
Although turtles live a long life.
Although the tortoise has a long life, it still has its time.
The snake rides the fog and ends in dust.
The old horse lurks, aiming at a thousand miles.
The martyrs were full of courage in their later years.
Surplus and contraction periods are not just in the sky.
Blessings that nourish grace can last forever.
I am glad to use this poem to express my inner desire.
These two poems show the enthusiasm and enterprising spirit of Cao Cao, who loves nature, despises fate, is vigorous and vigorous in his old age, and aims at a thousand miles, and expresses his lofty desire to change reality and unify the motherland.
