"If we want to develop Jiangnan, then naturally we must let Jiangnan be able to reap the benefits of Jiangnan. If we can't get benefits, then there is no need for us to develop Jiangnan. And the primary interest is all kinds of money as a manifestation. And we can't just spread all the investments evenly, so we can't make development at all. And in some places, the development conditions are not good, so no matter how much we throw money, it is impossible to make them what we want, and this will also cause a huge waste. We might as well set up a few local center counties so that we can use them to develop the surrounding state capitals as well. We can put the main funds into a few key places that can drive the development of the surrounding states and counties. ”

Eldest Sun Wuji listened to these theories, and couldn't help but feel that this theory was a bit level! Although the eldest grandson Wuji also had this rough idea, he was not as thorough as Jingwen said. The eldest grandson Wuji also knew that the investment cost of the imperial court could not be spread evenly, so it must be used centrally. But where to use it, this is also particular. The eldest grandson Wuji can also roughly know that if a developed state and county are erected in one place, this can drive the development of the surrounding area. Since ancient times, all the states and counties around the capital of a country have had a relatively developed economy. The reason why several accompanying capitals were set up in ancient times was actually an extension of Jingwen's idea of erecting a local economic center. It's just that in ancient times, this kind of economic development could only be understood, and if they were to sum up a set of theories, I am afraid that they would really not be able to do it. They just know that they deliberately develop a few cities, and then they can drive the development of the surrounding areas. Now Jingwen can clearly say the local central city. That's a very good word! Even the eldest grandson Wuji has to say that Jingwen's theory can be said to be a string of those things in his heart, and it is completely enlightened.

However, the eldest grandson Wuji will never admit that this is Jingwen's ability. In his eyes, Jingwen is also a chef who relies on some small cleverness to get to the top of the position, and he doesn't understand other real wisdom at all. But now this little chef can give such direct guidance to the country, which makes him, a person who has been from a famous family for many years, feel very faceless. If a chef can give any direction, then what else do they need them to do? Could it be that every chef is Yi Yin?

"Do you have any plans? For example, if you can't say what states and counties are chosen as so-called 'local center cities', what will be relied on for development. Then you are incompetent. A guy who only talks about it. The eldest grandson Wuji said.

Jingwen pointed to the Yangtze River basin, probably the later generation of Hunan and Hubei, and said: "Here, the land is fertile. Able to grow rice. Rice is a grain product. The taste is much better than our corn. And the yield is also higher. If rice can be planted here, it can be said that it is much safer for my Datang grain. I'm sure that as long as the rice generation here is fully ripe. The current population of our Datang, even if it quadruples, is enough to eat. ”

Li Chengqian and Eldest Sun Wuji's eyes widened, obviously not expecting this. None of them had heard of rice before, and the main food in Datang was corn before. And listening to Jingwen say that rice is not only more delicious, but also has a higher yield, of course it is tempting. Although the eldest grandson Wuji and Jingwen are not in harmony, he is still loyal to the Tang Dynasty and the emperor Li Shimin. If this kind of food can be obtained and can be grown in the south of the Yangtze River, then even if the world's population reaches hundreds of millions, it will be enough?

Of course, Jingwen knows that the generation of Hunan and Hubei is a treasure land of feng shui, and there is a lot of grain production. In ancient times, there was a saying called Suhu ripe, the world is full. Later, there was a saying, called Huguang is familiar with the world. More than 1,000 years later, the grain of the Huguang generation can be said to have supplied tens of millions of people in the north. Even in the 21st century, it is the main grain producing area in China. Therefore, the first article of Jingwen points to this, food is the lifeblood of the country's stability, and if enough food can be grown, then the country's prosperity is just around the corner.

"In such a small area, as long as rice is grown, will there be enough food for the whole world?" Li Chengqian asked excitedly.

Of course, it is unlikely that he will have enough to eat, but he is enough to feed more than half of the world's population. And with the current population of Datang, it is enough to supply the entire population. Jingwen said.

And Li Chengqian stroked this small piece of land on the map, obviously treating him as a treasure. Even Li Chengqian, an eleven or twelve-year-old child, knows that when people are hungry, they have to eat, and the more food, the better. I don't know why, Li Chengqian is very fond of eating. It was even more exciting to hear about a place where everyone in the world could be fed.

"However, because it is close to the Yangtze River, it is often prone to flooding! Therefore, we have to come up with a lot of money to build water conservancy. And building water conservancy is the biggest expense. But as long as the water conservancy is repaired, then this is the granary of our Datang. Jingwen said.

Li Chengqian nodded again and again, and immediately apparently agreed to spend money to build water conservancy here. And the eldest grandson Wuji is not stupid, of course he knows that although the construction of water conservancy costs a lot, as long as the water conservancy is repaired, it can be said that it is a granary with a profit of 10,000,000 years. This kind of investment, no matter how big the investment, is worth it.

"Moreover, we can requisition people to build water conservancy, and once it is repaired, we can arrange for them to farm nearby. And the level of water conservancy construction will affect their future farming income, so they will definitely work hard. We can use this method to replace the land in many places in Guanzhong and reduce the population pressure in Guanzhong. If Guanzhong has maintained such a large population, I can guarantee that within 40 years, my Datang will move the capital. Jingwen said.

"What? Moving the capital? Li Chengqian exclaimed.

"That's right, if you still maintain such a large population, and when the time comes, more and more, I'm afraid Datang will have to move the capital." Jingwen said.

Jing Wen had studied history, and of course knew that after Li Shimin's death, Tang Gaozong Li Zhi had set up a political center in Luoyang for a long time. Even, during the Wu Zetian period, the capital was set up in Luoyang. In fact, isn't this because the population pressure in the Guanzhong area of Chang'an is too great? For ancient times, the population of a capital was not always better. If the population of the capital is too large, then the officials of the imperial court, the families of the officials, and the countless garrisons will have to compete with the local people for food. However, in ancient times, the problem of road transportation was even more difficult, and it was difficult for road transportation to allocate grain from outside. This caused population pressure, and the capital was forced to move during the reign of Emperor Gaozong of the Tang Dynasty. Although there is no justifiable relocation of the capital, in fact, the political center has been transferred to Luoyang, and the capital has been moved without moving the capital.
