The price of salt has been pressed to death by the three envoys, and for salt merchants everywhere, the profit margin is very small, and the quality of official salt is very high today, which also makes the trade of smuggler salt completely disappear.

With the widespread promotion of the three treasures of home life, such as carboniferous, honeycomb coal and coal-saving stoves, the Great Song Dynasty, the Western Xia Kingdom and the Dali Kingdom greatly reduced the demand for wood, which of course polluted the environment and air quality around the city.

However, if the demand for trees is reduced in these three countries, it will not only improve the environment, but also reduce soil erosion.

This is particularly important for the Great Song and Western Xia Kingdoms, as reducing the cutting down of trees will slow down the desertification process in the Western Xia Kingdom, and at the same time, since the Western Xia Kingdom is located in the upper reaches of the Yellow River, reducing the cutting of trees will also play a role in curbing soil erosion. If this policy can continue for a hundred years, the Yellow River will eventually be cleared one day.

With the end of the Song-Xia war, the border markets were opened, and the economic exchanges between the Song and Xia became more and more.

Although the Song State received huge economic benefits, the Western Xia Kingdom also got a lot of sweetness from it.

In order not to desert the soldiers in the kingdom and lose the battle, Li Qianshun, the ruler of the Western Xia state, accepted Cai Dao's suggestion and concentrated his forces to attack the remnants of the Ganzhou Uighurs in Guazhou and Shazhou, also known as the Yellow-headed Uighurs.

To completely open up the Hexi Corridor, Cai Dao did not want to take the opportunity to restore the overland Silk Road, but to completely drive out the Uighurs, so that these people would later merge with the Uighurs in Xizhou. If Li Qianshun had the ambition and ability to do what Yelu Dashi did, he would also have vigorously assisted the Western Xia Kingdom in destroying the entire Xizhou Uighurs.

After all, a Dangxiang kingdom that embraced Buddhism was much stronger than a country that embraced other religions to be a neighbor of the Great Song Dynasty.

In terms of clothing,

Cotton cloth and quilts made of cotton have begun to spread widely in the Great Song Dynasty, and it seems that this new material has completely replaced hemp. In addition, with the transfer of a large amount of cultivated land in Jiangsu and Zhejiang to cotton, mulberry and tea trees, cotton cloth poured into the Xixia and Dali kingdoms, and even the Great Liao Kingdom.

Of course, with the increase of mulberry trees in the south, the price of silk also decreased a lot, and some of the more affluent people began to consume clothing made of silk. Of course, most of them are lady-brand lingerie.

This is a deal that Cai Dao found for several princesses.

All the underwear of later generations was made of silk, and these novel styles of clothes were very popular with the ladies of large families in Bianliang City.

If there is a woman, there must be a man, the Cai family first began to do this unique business, and later the silk merchants saw that it was very profitable, they did not dare to the idea of a big lady, but they dared to dare the idea of a big Cai family's ready-to-wear store. Therefore, there are more copycat men's silk underwear on the market, in fact, this is exactly what Cai Dao wants to see.

For silk, the expansion of domestic demand will further bring about great changes in the economy of the coastal areas in the Great Song Dynasty. The first thing to eat is the Jiangsu and Zhejiang regions around the canal, and then the entire coastal area of Shandong, and finally the entire coastal area of the Great Song Dynasty, so that silk becomes more and more. Then the Maritime Silk Road will become more prosperous.

In terms of living, the new brick-making method has been invented by the craftsmen under Cai Dao. However, he did not take it into his own hands, but trained many young brick makers in Bianliang City. After they left the school, Cai Dao drove them out of Bianliang City and let them go to various state capitals and counties.

Because, as the people gradually became richer, these people had a great desire to improve their living conditions.

Later, brick houses will gradually replace straw and mud houses, or houses made mainly of wood.

Okay, not to mention. The large-scale construction of the road made it faster and more convenient for the people to travel, and as the people gradually profited from the private breeding of horses, the current situation of the lack of war horses could not be changed for the time being, but those horses that were only used for transportation were still very good to feed. Therefore, in the county capitals and counties, the business of carriage and horse dealers has gradually increased.

However, with the smooth flow of roads, many people in the Great Song Dynasty will only choose the same place when they leave home - Luoyang City, and these people have poured into Luoyang City with their families and mouths, precisely for the title of the new capital.

In terms of population, with Cai Dao's emphasis on and training of doctors, as well as the rigid definition of the age of marriage for women, ordinary people can afford to see doctors when they are sick, and the birth rate and survival rate of babies are also improving.

Moreover, there were no endless wars with neighboring countries, no robbers and bandits rampant in the region, no large-scale famine in the northern land, and the death of the people was further reduced.

It took less than three years for a population explosion to occur, and it's not hard to imagine.

In terms of military affairs, Cai Dao recommended two chief officials of the three ya, Cao Hu and Pan Xiong began to conduct a rectification training of the forbidden army in the capital in the first year of Tianyou, and many soldiers of the forbidden army who remained in the Shaosheng period were eliminated.

In the years when Cai Dao was lurking, except for the Liao-Song border, the war progressed very smoothly in all directions, which also made Zhao Xu and Zhang Dian a little complacent. They have always looked down on the warriors, so the supervision of the forbidden army has been relaxed.

This also led to the rapid slackness and degeneration of many soldiers and officers of the forbidden army who remained in office, because they themselves were old fritters in the forbidden army, and they all knew how to perfunctory officials, plus other people's lack of attention. Most of these people were junior officers.

When discussing any disposition of them, there were many deputy privy councillors who disagreed with Cao Hu and Pan Xiong for making such a big deal out of it. Because, a big war is imminent, and if these low-level officers are dealt with rashly, it will not only cause unease among the soldiers, but also greatly weaken the combat effectiveness that the forbidden army has just formed, and the gains outweigh the losses.

But Cai Dao still overrode public opinion and agreed to Cao Hu and Pan Xiong's training plan, and the soldiers he wanted from the forbidden army were not for them to fight in the field with the Liao Iron Cavalry, but only for them to be able to hold the city on the border.

However, Cai Dao also assigned Cao Hu a task, that is, to select the elite among the 300,000 standing forbidden troops, specialize in training key points, and select more archers who are good at archery.

In today's Bianliang City, there are 300,000 soldiers in the standing forbidden army, and the number of Tuntian soldiers has reached 700,000. Moreover, the average age of these million-strong proscribed soldiers was no more than thirty years old.
