The ancient Korean Peninsula was connected to the landscape of the Central Plains Dynasty and had a deep historical origin.
In the late Period of the Northern and Southern Dynasties, the Korean Peninsula was in a confrontation between Goguryeo, Baekje, and Silla. Goguryeo, on the other hand, resembled Cao Wei during the Three Kingdoms period and was the most powerful. A sentence in the Old Book of Tang sums up the attitude of the Han people toward the Korean Peninsula: "The Goryeo people, the border yi and the lowly, are not enough to be benevolent and righteous, and cannot be blamed for common etiquette." "Seeing them as barbaric untouchables, or even as fish turtles, there is no need to stir up the masses. But if: "If you violate the Festival of the Lost Lord, you can also be cursed; Disturb the people and destroy them. ”;
In 597, Goguryeo joined forces with the Jurchens, the ancestor of the Jurchens and later the Manchus, to attack the western Liao military garrison, only to be repulsed.
After the Sui Dynasty Emperor Yang Guang ascended the throne, he realized the seriousness of the problem on the side of Goguryeo, "This is tolerable, but what can not be tolerated?!" "Three successive wars against Goguryeo were waged.
In 612, the Sui Emperor sat in Zhuo Commandery and commanded the generals. The army was divided into twenty-four roads on the left and right, a total of 1.13 million, and one army was sent every day, connecting more than 900 miles before the army was completed for more than 40 days. The Book of Sui "The grandeur of the late ancient masters, but the untouched".
However, in order to avoid the greedy and adventurous advance of individual generals, the Sui Emperor ordered them to communicate with each other and report to the emperor on their march and retreat; and the enemy surrendered immediately and was not allowed to attack.
This was already a taboo for soldiers, because of the constraints of the emperor's orders, the warplanes were fleeting, and Goguryeo repeatedly surrendered.
The generals were sluggish, morale was low, and the cold weather made it difficult for the imperial army to feed, and the first expedition to Goguryeo ended in failure.
Because the empire was not long after its founding, the foundation was not solid, and there were serious internal and external troubles, and the last two attacks on Goguryeo were also fruitless.
The Sui Empire continued to use troops against Goguryeo, which increased the burden on the people and boiled over the people's grievances.
In 611, Wang Bo revolted in Zhangqiu, Shandong, and composed "The Death Song of the Endless Liaodong Wave"
"Changbai Mountain Former Zhi Shiro, pure red Luo Jin back crotch... Go up the mountain to eat roe deer, go down the mountain to eat cattle and sheep... For example, Liaodong died, beheading what hurt. ”
The death knell of the demise of the Great Sui was sounded.
"The bamboo of the South Mountain is endless, and the sins of the book are endless; the waves of the East Sea are determined, and the evil is difficult to exhaust."
The Sui Emperor was a great evil man who concentrated almost all the evil varieties of mankind, and committed almost all the crimes that human beings can commit...
In 618, the Right Tun Wei general Yu Wenhua, who was in charge of the Janissaries, launched a rebellion at Jiangdu, and the Sui Emperor was killed.
After Yang Guang ascended the throne, he opened canals, created keju, built the Great Wall, placed granaries, attacked Tuguhun, and conquered the Khitans... Wenzhi martial arts were not inferior to those other emperors in the annals of history.
Not only that, Yang Guang's literary talent is also remarkable. For example, "Drinking Horse Great Wall Cave Line", this poem:
The autumn wind rises and travels thousands of miles. Whatever you do, build the Great Wall across the desert.
Some people believe that the gas is powerful and has the wind of Wei Wu.
Let's look at the poem "Spring River Flower Moon Night":
The twilight river is not moving, and the spring flowers are in full bloom. The flow waves will go to the moon, and the tide will bring the stars.
Zhu Qian: "The Tang people are capable of being superior." ”
How to evaluate the Sui Emperor, Pi Rixiu's "Bian River Huaigu", more representative:
The Sui Dynasty died in this river, and it is still thousands of miles away from Tongbo. If there is no Water Temple Dragon Boat Matter, there is not much Gongyu Theory.
History, or to leave it to posterity to comment.
