In this battle for the direction of strategic development, Zhao Yu has always been at a disadvantage, but he still insists on his view of taking the southeast first, and constantly tries to convince the ministers. Pen ~ fun ~ Pavilion www.biquge.info people who have played Go, especially beginners, often like to occupy the corner, form a stable situation and then develop to the center, so there is a 'golden horn and silver edge'. From the perspective of military geography, China's geographical pattern is also like an irregular Go board, on which Guanzhong, Hebei, Southeast and Sichuan are its four corners, Shanxi, Shandong, Hubei and Hanzhong are its four sides, and the Central Plains is its central hinterland.

The four corners of the land have their own unique geographical conditions, generally have a relatively superior situation of mountains and rivers, have a relatively stable rear and can rely on the mountains and rivers to rely on, can be a kind of attack, retreat can defend the situation; There are superior economic conditions, which are sufficient to support and support a huge political and military group; It has a certain social foundation and is prone to forming a certain social and political force. Therefore, at the beginning of the rise of a kind of force, occupying the dangerous land of the four corners of the mountains and rivers can establish a base area, operate calmly, accumulate strength, and lay the foundation for entering the world in the future.

In the four sides, there are generally more dangerous mountain and river situations, but the comprehensive conditions of these regions are not as good as those in the four corners. They are all sandwiched between two corners, they can come, they can go, they are not only the link between the two sides, but also the focus of contention between the two sides when they confront. Their topographical characteristics are also consistent with their status, with both traffic passages for both sides to enter and exit, and dangerous points to be defended; Moreover, they have a relatively close passage with the Central Plains. Therefore, although the males were in the Central Plains in history, the males who could really participate in the deer competition were not as good as the Central Plains, but tended to be four horns.

Historically, most of the forces that finally completed the great cause of unifying the world tended to be in four corners. And most of the forces that finally completed the great cause of unifying the world also started from the dangerous places of the mountains and rivers in the four corners. First according to the four corners of the mountains and rivers of the dangerous land, because of the time, according to the geographical advantage, win people, calmly operate, the accumulation of violence can often achieve a hegemon. However, this is only the stage of accumulating the completion of life, and if we want to unify the world, we must complete the accumulation stage, and the principle of forging ahead depends on the management of the Central Plains.

Therefore, in the stage from governance to chaos, from integration to division, it is often difficult to divide the land of the four wars in the Central Plains, and it is easy to build up strength in the four corners of the mountains and rivers, and then expand to the two wings, and then develop to the Central Plains and enter the world; In the stage of moving from chaos to rule and from division to convergence, only those who go out of the four corners to fight for the Central Plains have the opportunity to fight for the world, and the upper ones can pacify the Quartet and unify the world; The second can be divided into one side and dominate for a while. When the conditions for reunification are not ripe, local order can also be established in the four corners of the land, and one side can achieve hegemony.

From this point of view, Xichuan and Southeast are on an equal footing, but Zhao knows that history can be used for reference, but nothing is set in stone. With the evolution of the general trend of history, in fact, the status and strategic significance of different regions are not fixed at any time, but are different with the differences in the overall political and military situation at that time, and the status and strategic significance of different regions have changed, which is illustrated by the trend of China's political center of gravity moving from west to east.

In the era when the political center of gravity is in Guanzhong, the status of Guanzhong goes without saying; Later, after a period of vacillation, the political center of gravity shifted to Hebei. This process was accompanied by a decline in the status of Guanzhong and an increase in the status of Hebei. This change has also had a certain impact on the status of other regions, the political center of gravity is located in the era of Guanzhong, Hubei is the link between the northwest and the southeast, and the status is more important; After the political center of gravity was moved to Hebei, with the decline of Guanzhong's status, Hubei's status also declined, while Shandong became the hub of the political center of gravity and the economic center of gravity between the north and the south, and its status became pivotal.

At present, the capital of Mengyuan and Yuanding, that is, modern Beijing, is within the scope of Hebei, and Shandong is the wing of the southeast. However, to occupy Xichuan and seek the Central Plains, we must first capture Guanzhong, and then go down to Hebei, and Shaanxi and Gansu are close to the old capital of Mengyuan and Yuan, so they will be in a situation of being flanked by the enemy on both sides. Moreover, it was also very difficult tactically for the troops to attack on the back during the attack, and few of the Northern Expeditions in Sichuan were successful, but most of them were destroyed by the enemy.

When Zhao Yu was trying to persuade the ministers, everyone was also trying to make him follow the advice, and also advised him from many aspects such as humanities, products, and folk customs. He thought that there was no reason to say that there was a bias, and many of the situations had changed dramatically.

They said that the ancients often said that the southern folk customs are weak and can be peaceful. It is true that at that time, the people in the south did not have much intention of resisting, and the people in the north were fierce, especially in the northwest and Hebei. Moreover, the northern nomads mostly live by hunting, mainly eat meat, exercise more, and have a relatively robust body; Since the Han Dynasty, the Han people have admired Confucian culture and advocated the pursuit of fame and fortune, which can be seen in their quality.

Zhao Yu disagreed with this, the people in the southeast in ancient times were brave and martial, which was also a condition that the regime based in the southeast could rely on. The geographical chronicle of the Book of Han records the customs of the southeast: the kings of Wu and Yue are all brave, so their people are still good at using swords, and they are prone to death. In the Spring and Autumn Period, Wu Yue was able to compete for hegemony with Qi and Jin and other Central Plains powers, Xiang Yu led 8,000 Jiangdong disciples and made the Qin people fearful, and Xie Xuan and Liu Yu led the Beifu soldiers who repeatedly defeated the strong enemies in the north during the Eastern Jin Dynasty.

The eastern part of Zhejiang and Jiangxi are also quite the same, especially the Huainan area, which is the place where the displaced people have migrated back and forth for generations, and the displaced people have formed many clans, and the human nature is restless, the atmosphere is decisive, and the scourge is hidden, and the death is like home, the war is expensive, and the war is expensive, and the people are accustomed to the chaos of war, and they are displaced from the chaos, and they form an armed force to protect themselves, which is a potential armed force that can be used. In later generations, there were even Guangxi wolf soldiers who were known as the strongest soldiers in the world.

In terms of material supply, Zhao Yu also admitted that in terms of available mineral resources and mineral development capabilities, the most relevant to cold weapons is coal and iron resources, which are superior in the north, and have continued until modern times. For the supply of grain and meat, the traditional crops in the north include millet, millet, millet, wheat, sorghum, etc., which have a relatively strong ability to adapt to natural conditions, and the output is relatively stable, which is conducive to making strategic reserves.

However, after the Song Dynasty, the introduction of Champong rice has changed this situation, and double cropping a year has become common, unless there is a large-scale disaster, military food is guaranteed. The supply of meat is a problem, and Zhao Yu also has a deep understanding in Caiqiongzhou, but he successfully used the fish in the rivers and seas to solve the dilemma of protein deficiency, and eating fish has also become a habit among the armies. However, the dense water network in the south naturally does not lack fish replenishment, and the cost is much lower than that of raising livestock.

In addition, due to geographical factors, the north is suitable for horse breeding, especially in the Mongolian steppe and surrounding areas. In the era of cold weapons, the role of war horses is great, the cavalry in the field has an absolute advantage in the face of infantry, the infantry can not beat the cavalry is difficult to escape the result of the annihilation of the whole army, it is difficult to pursue and expand the results of the war, Zhao Yu admits that the role of the cavalry is great, and also knows that it is difficult to obtain war horses, and now the Qiongzhou army is also difficult to further expand because of the insufficient number of war horses.

However, it is probably not a good idea to use the infantry army to go out of Xichuan to compete with the enemy's cavalry, and the Qiongzhou naval army dares to say that the world is invincible, so it can go on an expedition in the sea and be unimpeded in the inland rivers. However, the lack of water in the Guanzhong area is the norm, and the southeast is indeed full of rivers, so why should we attack the enemy's strengths with our own shortcomings? In addition, there are abundant water and grass in the Jianghuai region, although it is not as suitable for horse grazing as the north, but it can also solve the risk of lack of horses.

In addition, the difficulties mentioned by the ministers also exist whether they take Xichuan or occupy the southeast. Geographically, the northern plains are predominant, which is conducive to marching and fighting, so it is relatively easy to unify the north. However, the high mountains and rivers in the south are densely forested, and there are many natural barriers, which are not conducive to marching and fighting, so it is relatively difficult to unify the south. The northern region, which is easy to reunify, is prone to form an advantage in concentrating forces and resources, and to the south, it is easy to break through each other.

The north is relatively cold and has a relatively long winter, while the south is relatively warm, with short and almost no freezing. This difference in climate makes the climate influence relatively small when attacking from the north to the south, and the climate influence is huge when attacking from the south to the north, especially after the arrival of winter, it is very difficult for the southerners, who have rarely seen snow in the north, in the middle of winter, let alone fighting. Moreover, the logistical replenishment in winter will be very difficult, and it is easy to cause very serious failures.

Zhao Hao believes that now the Mongols have unified the whole country, which is a false proposition, and it must be faced no matter what. And the division of the southeast is not useless, he remembered that some people in later generations once said that 'the elders of the south are not as good as the southeast'. The southeast is located in the subtropics, with more rain and vertical and horizontal rivers. The Yangtze River and the Huai River flow in an east-west direction, between the north and the south, and together with their tributaries, they form a dense river water network, which is enough to absorb the impact of the northern iron horse. In terms of blocking the momentum of the northern iron cavalry, the Yangtze River is indeed an insurmountable moat.

The south can make use of these rivers and waterways to build military strongholds, hold some major passages, and give full play to its expertise in water warfare and city defense warfare. In the entire South, there is no other region with as many rivers and waterways as the South-East. In addition, the rainy season in the south is humid and hot, and people and animals in the north are not adaptable. In this way, if the northern forces cross the Huai River and continue to penetrate southward, they will face great difficulties in terms of climate and environment, and find themselves in the unfavorable situation of abandoning their strengths and making use of their shortcomings.

The economic conditions in the southeast region are also relatively good. The development of Jiangnan was originally relatively later than that of the north, but the successive turmoil in the north will lead to a large number of displaced people moving south, and the displaced people will bring advanced production technology to the south, and the turmoil in the late Eastern Han Dynasty caused the first peak of the southward migration of displaced people in Chinese history, and after the Yongjia Rebellion, the Central Plains clans and people moved south in large numbers again. In particular, the southward migration of the Song Dynasty forced the northern displaced people to move south one after another, which further promoted the development of Jiangnan and the economic development of the southeastern region.

The Taihu Lake area in the lower reaches of the Yangtze River is a wealthy economic zone with dense population. During the Sui and Tang dynasties, the southeast wealth was relied on by Guanzhong, and the wealth of Yangzhou was often the best in the world, and it was called "Yang Yi Yi Two" at that time. The opening of the Grand Canal in the Sui Dynasty and the Cao Yun in the Tang Dynasty all had the intention of transferring the wealth of the southeast to supply Guanzhong. The Yuan, Ming and Qing dynasties built the capital of Beijing, and also relied on the southeast economically, and the re-dug Grand Canal was transferred to the southeast to supply the Beijing division. There are many rivers and waterways in the southeast, and the transportation is convenient, and the scarce things are also easy to be replenished, and the scope of its transportation and trade is more extensive.

Most of the regimes established in the southeast were able to unify half of the southern part of the Yangtze River, while a situation of confrontation between the north and the south was formed with the north, and this also had a great deal to do with the social foundation of the southeastern regime. Most of the regimes in the southeast were housewarming regimes, and they were the preservationists of the Zhengshuo in traditional Chinese politics and the advanced culture of the Central Plains. After the Central Plains regime moved to the southeast, the advanced social and political culture of the Central Plains constituted an important foundation for its rule, and the Song Dynasty moved south again, and the southeast once again became the gathering place of the Central Plains social, political and cultural circles.

These conditions provided the economic basis for the political and military status of the southeast. However, it is not without its weaknesses, and the housewarming regime itself is the product of forced migration by a strong enemy, so it inevitably has the characteristics of being partial to peace and not wanting to make progress. Historically, most of the regimes based in the southeast took the Northern Expedition and the recovery of the Central Plains as the slogan, but most of the regimes based in the southeast were able to unify half of the south of the Yangtze River and form a situation of north-south confrontation with the north......

Zhao Yu knew that the war was fought for money and food, and the people's aspirations, and the southeast was the best counteroffensive base. This made it difficult for him to understand why the courtiers of the Xing Dynasty were bent on going to Xichuan, and later thought that perhaps it was the overthrow of the imperial court that made them lose the confidence to run the southeast again. As for the capture of Guanzhong, they are afraid that they themselves will not believe it.

Timidity and cowardice, as well as the existence of Gou An's thoughts, made westward expansion the mainstream of the Xing Dynasty. And Zhao Yu is 'addicted' to being the emperor at the moment, of course he doesn't want to be just the lord of Xichuan, but he wants to restore the old land and return to the Central Plains. However, the two factions quarreled and discussed for a long time without success, and he was not in a hurry before, he could sit on the mountain and watch the tiger fight, thinking that it would be healthier for everyone to quarrel. However, at the moment that Kublai Khan is about to die and the civil strife in Mengyuan is about to start, he naturally can't wait any longer, but it is not easy to form a unified opinion in such a situation.

Now that Yang Lian Zhenjia is here, he has a chance, and Zhao Yu believes that in the case of the theft and excavation of the imperial tomb, the westward party can still endure this shame. And if they are still stubborn, they are afraid that their officials will also come to an end, although what they have done is not honorable, and it can even be said to be very despicable......
