His Majesty Emperor Taizong Xiaowen

November of the first eleventh winter. The emperor is fortunate to represent the country. In the first month of spring, the capital has been returned since the generation.

In the summer of June, Liang Huaiwang Liu Yixu. Childless. Jia Yifu said: "Since Your Majesty can't customize it, the current situation is just a matter of passing it on again and again, and the princes are still uncontrollable, arrogant and powerful, so that the Han law cannot be implemented." His Majesty can only use it as a wall, only Huaiyang and Dai Erguo. Generations of the Xiongnu in the north. Be neighbors with strong enemies. It's a blessing to be able to protect yourself. Although Huaiyang is larger than the princes, it is enough to become the bait coveted by the princes. And it is not enough to help His Majesty to have a ban. Fang Jin's system is in His Majesty, and with the foolish tricks of the ministers, Huainan will be exchanged for Huaiyang. and set up a queen for the king of Liang. Cut the two or three cities and Dongjun in the north of Huaiyang to increase the strength of Liang, if His Majesty feels that it is not feasible, he can make the king move the capital to Juyang, and Liang starts in the north of Xinyun and ends at the river. Huaiyang Bao Chen southward. It is connected to the Great River. Even if the great princes have different intentions, they dare not have a conspiracy to lend him a gut. Liang is enough to protect Qi Zhao, Huaiyang is enough to ban Wu Chu, Your Majesty can sit back, and there will be no worries about Shandong. This is the benefit of the second. It can be peaceful today, because the princes are still young at this time. In a few years, His Majesty will see you. At the beginning, Qin worked hard day and night to get rid of the Six Kingdoms. Now His Majesty is trying to control the world, and he is wishful, but he arches high to form the shape of six countries, which can hardly be said to be wise. Even if His Majesty is fine, but he has a chaotic vendetta, and he is familiar with it, and after 10,000 years, passing the country to the old mother and weak son will make the country restless. It cannot be called righteousness. ”

The emperor then moved Liu Wu, the king of Huaiyang, to the king of Liang from Jia Yi's plan, with Mount Tai in the north and Gaoyang in the west. There are more than 40 cities in Deda County. After the year, Jia Yi also died, and he was only thirty-three years old when he died.

Liu Xi, the king of Yang, was the king of Huainan.

Xiongnu Kodi Dao.

When the number of Huns was a border trouble. The prince's family ordered Chao to mistakenly talk about military affairs. He said: "In the art of war, it is said that there are generals who will win, but there are no people who will win. From this point of view, the security border and meritorious fame lie in the good generals. Don't choose carefully. The minister also heard that there are three prerequisites for using troops to fight together, one is to obtain the terrain, and the other is to make the soldiers accustomed to uniform. Third, it must be sharp. The Art of War says that infantry chariots, bows, crossbows, spears and arrows must be appropriate. If it is not suitable, it is not one in ten. If the soldier does not choose to practice, the pawn does not obey the practice, the daily life is not fine, the movement is not collected, and the profit is not in time, then the front hit and the rear solution, and the finger of the golden drum is lost. This is the fault of not being accustomed to the soldiers, a hundred is not ten, and the army is not perfect, which is the same as empty-handed. The nail is not dense, which is the same as the flesh. The crossbow cannot be far away, and it is the same as a short hand. Shooting can't hit, the same as no arrow. Medium can not enter, the same as no cluster. This is all because the general will not be able to save troops. Five is not one. Therefore, the art of war says that the weapon is not good, and the pawn is not available to the enemy. With its generals against the enemy, they will not know the soldiers. These are all important things for soldiers, and they must be done cautiously.

The minister also heard that the small and big are alien, the strong and the weak are obsessed, the danger is different, and the humble body is strong, which is the situation of a small country. Joining forces with small to attack big is forced by the situation of the enemy's conquest. Attacking barbarians with barbarians is again a decision made in accordance with the situation in China. The topographical skills of the Xiongnu today are different from those of China. Up and down the hillside, in and out of the stream, the Chinese horse can't do it. The dangerous road tilted sideways, and galloped and shot, the Chinese cavalry could not do it. Fatigue from wind and rain, hunger and thirst, Chinese people can't do it. This is the long skill of the Huns. If you change places in the plains, the Huns are easy to scratch. If the crossbow halberd shoots far away, the bow of the Huns cannot be blocked. Sharp armor, mixed long and short, crossbows come and go, soldiers are in front, then the Huns' soldiers can not be. Dismount and fight, hand-to-hand combat, and the Huns' soldiers cannot be used. This is China's long skill. From this point of view, the long skills of the Xiongnu are not comparable to the long skills of China, and His Majesty has raised 100,000 people to punish tens of thousands of Huns. It's a many. Despite this, the soldier is the murder weapon. War is a dangerous matter. Therefore, the big is small, the strong is weak, only between the admiration, the death of people is to win, once the frustration is sluggish, it will be too late to regret. The way of the emperor, everything is based on the principle of perfection, and now there are thousands of people who have returned from the barbarians of Hu Yiqu, and their food and drink skills are the same as those of the Huns. If you give them strong armor and strong bows and arrows, and give them good horsemen from the border counties, and let them choose those who can learn their customs and control their hearts as generals, and lead them with the express covenant of your majesty, there are dangers and obstacles, and let them send troops as they deserve. The flat passage is based on the official system of light vehicles, and the two armies are inside and outside. Each uses its own strengths, this is a perfect technique. ”

The emperor admired his idea very much and gave him a letter to reward him.
