Due to the investment of metal axles and bearings, today's four-wheeled baggage trucks can carry up to 30 stones, or even more, which is twice as much as the old models in the early days, greatly reducing the pressure on logistics and transportation.

With more cars on the road, more goods are transported, caravans become more frequent, cities prosper, and chaotic traffic makes the streets more chaotic, and tragedies are common.

In order to facilitate the management and reduce traffic accidents, at the end of 644, the capital county implemented the practice of acting on the right, and set up public carriage and horse farms and private parking spaces in large cities such as Chenling and Yongxing.

Seeing Bailiyan's arrival, the big shopkeeper explained the situation in detail, and his brother-in-law Qiao Cheng also arrived, and was discussing countermeasures with Jiang Rong, Lord Qiao and others with Ding Su on the second floor.

After talking with the big shopkeeper, Bai Liyan turned around and said to the young man beside her:

"Wei Qi, go feed Feiyu some food."

"No!"

Wei Qi was a teenager who was adopted from Dekang that year, and entered the Hou Mansion with his sister Ning Ning, and their grandmother worked in the Hou Mansion for several years and passed away before last year.

In view of the harsh environment of Sun State, Baili Yan played the King of Xian, collected orphans, and filled in the Xianguo territory to supplement the national population of Xianguo.

The 20-year war and the five-year rebellion caused the Xianguo to lose more than 2 million people, and the population of its own people plummeted to more than 5.5 million.

On the one hand, the orphans in the war zone were systematically relocated to the territory of Xianguo and placed in foster care in various parts of the relatively wealthy prefectures, and on the other hand, official orphanages were set up to take in children under the age of 12 and young people between the ages of 12 and 16, and semi-military management was carried out, labor camps were set up to engage in simple agricultural manual labor, literacy and popular science literacy courses were arranged, or they were sent to Guangxin, Ruitian, Yongxing, and Shanling to become apprentices to learn industry skills and expand the scale of basic work.

As for the female baby, it has basically become a big welfare at the moment, for those who have a boy in the family, the girl will become a daughter-in-law after she is raised, and she will be a maid and maid when she enters a large family, and the Xianwang Palace has absorbed more than 800 female babies for this purpose to enrich the employment in the palace.

Some of them are over the age of 12 and are sent to Ruitian to work as simple female workers, especially in food, textiles, and medicine, and cultivate good habits from an early age, which will help them achieve professional production in the future.

In order to encourage adoption, the imperial court successively introduced preferential policies, not only reducing some taxes, but also issuing monthly food subsidies until the policy automatically expired after the age of eighteen.

Since the beginning of the year, a total of nearly 600,000 orphans of all ages have been resettled, and the state treasury has spent more than 2 million new dollars in money and grain for this purpose.

Bailiyan was unmoved, and not only did she stop allocating funds, but also added more than 800,000 yuan of money and food from Yongxing and Houfu every year to increase the supply and collect more children.

And it turns out that five years later, teenagers between the ages of 12 and 16 are now generating far more socio-economic benefits than the millions of dollars they have invested.

For this reason, since three years ago, various localities have successively implemented a system of "regular meals", and all subsidies are not distributed to local governments, and the government runs government-run canteens, and adopted children go to the government-run canteens to eat.

Even so, it is often the policies and countermeasures that still can't stop the impostors.

However, the world is like this, it is impossible to be exhaustive, and it is the norm in any era to ensure the relative basic fairness within the greatest scope, and there can never be absolute fairness and justice.

After Xiaoqi and Ning Ning entered the house, Bailiyan gave the brother and sister the surname "Wei" and arranged for them to study. After Jiang Jie was promoted to the governor of the capital, Bailiyan ordered him to command the military battalion and supervise the exploration of new tactics.

In 642, after Sikong Nan, Bai He, Su Hong, Fang Liang, Tian Peng and others were promoted, Su Hong was transferred to Yongxing and Lu Zhao was in charge of Yongxing secrets, Fang Liang and Tian Peng were stationed in Zhongxing, Tailai, and Longsheng, Bai He was in Ruitian, and Sikong Nan was transferred to Guangxin to supervise Lincheng. In particular, Ruitian, Lincheng, and Yongxing are involved in military secrets, and non-cronies are in charge.

At the same time, King Xian intends to reduce power, except for Jiang Jie, Sikong Nan, Su Hong and others have no actual military power, and they have followed Bailiyan to conquer the south and the north for more than 20 years, and most of them are more than half a hundred this year, Bailiyan feels very guilty, Ruitian and Guangxin are fat, and they can be regarded as compensation for so many years of battlefield killing.

Sent Wei Qi away, Bai Liyan went to the second floor alone, the second floor of the department store is still forbidden to outsiders, and outsiders can't easily come up.

Following the sound to the council hall, Jiang Rong, Qiao County Lord, Xiao Er, Qiao Cheng, and Ding Su gathered around the square table to drink tea and chat, and there were sumptuous snacks and pastries on the table.

Seeing Bai Liyan appear, without waiting for Jiang Rong to speak, Qiao Cheng stood up and stepped forward and said:

"Brother-in-law, you are finally here, and you are the only one missing."

Bai Liyan closed the door casually, and said as she walked inside:

"It's for the lack of gold and silver."

Lord Joe answered:

"But no, my father is almost blind, and he lives in Qianfang all day and orders all the people to pass the scales, but I don't know, I'm scared."

The lord of Qiao County danced with his hands and his expression was exaggerated, and Bai Liyan could completely imagine what kind of mood Qiao Lian was in, just imagine that a million silver was less than a hundred thousand overnight, and who could stand it in his heart.

And not to mention less, you have to exchange the full amount of silver, this back and forth is hundreds of thousands of inverted price differences, and the loss is lost.

The Xuanting Marquis Mansion, one of the best in the world, where has he suffered such a huge loss, Bailiyan pondered that Princess Lanyuan would soon have to kneel and cry in the palace.

After waiting to sit down, Bai Liyan continued:

"Brother in-law, how serious is the situation of the inventory of the Qianfang vault."

"There is a shortage of silver by one and two cents, and gold is nine cents less, and this is less than forty percent of the scales, and there is a loss of nearly 100,000 inches of silver, and a small inch of gold of 5,000.

300,000 roots, Xianguo 20 years ago, the treasury couldn't save more than 300,000 roots, these bad profiteers. Brother-in-law, has the cabinet come up with a solution? Qiao Cheng screamed and raised three big fingers, as if cutting his flesh.

"At present, there is no effective means to prevent the shortage of gold and silver from flowing into Xianguo, so we can only produce more balance scales as soon as possible for trading in various markets and commercial markets. You have been discussing for a long time, have you come up with a good idea? ”

"What else can be done about each full amount of scales."

Lord Qiao said in frustration, and it seemed that there was nothing he could do. At this time, Jiang Rong took over and said:

"Swallow, Yongxing City is so powerful, can you use any means to make the gold and silver stay and not out of shape?"

"Anyway, I haven't thought about it, there is a way, but I can't do it right now."

It is not impossible to prevent the acquisition of precious metals by acidolysis and substitution, and it is possible to gild one-third of the length of the inch of silver, and silver two-thirds of the inch of gold.

Because the metal layer plated with gold and silver is thinner, and the process of acid corrosion replacement is uniform corrosion, so the gold plating and silver plating will disappear in the corrosion, so that the gold and silver plated inch silver, inch silver has a certain anti-counterfeiting, long-term use of wear still has a high degree of discrimination, in addition to plating other metals anti-counterfeiting, anti-corrosion.

However, metal plating, or electroless plating, electroplating is not yet available, and electroless plating has the problem of metal activity.

Both can only use inert metals to electroless plating of active metals, and gold is more inert than silver, and the chemical value is high, and the chemical method is used to plating gold with silver, carbon disulfide is useless, and highly toxic cyanide must be used.

Due to the constraints of the above two technologies, it is difficult to coat gold and silver at present.

The only physical means is to strictly control the imports, and all the gold and silver are weighed one by one, but after the scales are passed out, it is difficult to ensure that the precious metals issued by the Xianguo will flow into the country and be stripped of a layer of skin after a few years. Moreover, the transaction will be more cumbersome and easy to cause economic and financial obstruction.

Seeing that Bailiyan was also helpless, the atmosphere immediately fell a lot quieter, and then Xiao Er said on the side:

"Master Hou, Xiao Er has a way, but I don't know if it's useful."

"Oh, let's hear it."

"At present, dining, bathing, and teahouses are all issued with tickets, and a ticket is written with a quota, and a signature is also used at the checkout, so that customers can know how much they use, and then settle the bill. If the gold and silver deposited in the money mill and the treasury can also be used to sign tickets, not only does it save the gold and silver from being passed over many times, but also can use the signed tickets instead of gold and silver, wouldn't it be more convenient. ”

After Xiao Er's words were finished, Qiao Cheng said first:

"The third lady thinks very well, but now the gold and silver deposited in the money shop are all short of two catties, but what is spent is a full amount of gold and silver, how can the ticket be used instead."

"That's right." Jiang Rong affirmed, and then said: "The ticket is marked by the price, which is dead, and the gold and silver are innumerable, and there is always a shortage for several years and more than ten years. ”

Everyone went on for a while, and Ding Su interjected:

"Master Hou, the old man has a sentence that I don't know if I don't know what to hear."

"Ding Caidong, please speak."

"The old man used to go to the West Sea to trade, and every time he carried tens of thousands of gold and silver, he could be described as rich and rival the country. With the fame of these years, hundreds of people on the road are still worried for fear of being robbed. Therefore, there are many private gold and silver belts, which are not only inconvenient to carry, but also unsafe. And there is a shortage of gold and silver traded in various places, and it cannot be weighed one by one.

The old man thought that it might be a good thing if he could link gold and silver to the signing of tickets, but what the eldest lady and Qiao Shaohou said also made sense. There is always a shortage in the circulation of gold and silver, and the face is a fixed amount of dead tickets. It is not a big problem in the private circulation, but if it goes into the national treasury, there are not many people, but ten hundred thousands, that is an incredible amount. ”

"I understand what Ding Caidong and Xiao Er mean, you want to use tickets instead of money, so that the money is equivalent to the signed tickets, and there will be a shortage of money in circulation, so the signed tickets of the same price and the gold and silver of the same price cannot guarantee sufficient amount, but this means."

"Exactly."

Ding Su nodded, and Lord Qiao answered:

"Brother and Sister Rong also mean this, I just thought, at present, Yongxing City is so capable, thousands of white paper every year, and it is printed with newspapers and postal stickers, and other countries can't imitate it, if the city signs the ticket for money, and gold and silver are linked, just like Ding Caidong said, it not only eliminates the handling and loss, but also convenient to use, wouldn't it kill two birds with one stone."

Lord Qiao said that Baili Yan's heart was in the heart, and he invisibly pushed Jingrong to a new height.
