After solving the problem of the subject country, there will be an important meeting in the next step, that is, currency reform, which is mainly the reform of the currency value, the reform of the exchange rate, and the reform of the silver standard.

In recent years, Zhang San has been hoping to change the copper standard of currency to the silver standard, Zhang San doesn't know why, he just thinks that the silver standard is better than the copper standard, so in recent years, Zhang San has been crazy to mine various gold and silver mines, buy gold and silver to increase gold and silver reserves.

Now Zhang San has occupied Shandong again, obtained the gold land of Zhaoyuan, plus the reserves of the past few years, the conditions for changing the silver standard system have been ripe, and the currency value of Zhang San has been changed with the Great Song Dynasty, including the consistent 770 Wen is the same as the Great Song Dynasty.

That's because the Great Song Dynasty is the most developed economy, Zhang San is only a small country, after several years of development, now Zhang San has the ability to go his own way, and the Great Song Dynasty economy is getting worse, Jiaozi collapsed, copper coins depreciated, and now Tokyo's cooking cakes have risen to seven cents a piece, so the monetary system of the Great Song Dynasty is basically finished.

The new monetary system, based on silver, is equal to one thousand wen money, ten taels of silver is equal to one tael of gold, as for the relationship with the Great Song Dynasty currency, it is not directly linked to the Great Song Dynasty coins, but linked to silver, according to the Great Song Dynasty coins and silver currency changes to exchange the Great Song Dynasty coins.

In this way, the state of Qi completely got rid of the impact of the collapse of the financial system of the Great Song Dynasty on itself, and the smallest unit of paper money was one yuan, one yuan was equivalent to one tael of silver, and the largest monetary unit was one hundred yuan.

As for the small denomination banknotes that are not being issued now, the first is that everyone's panic about Jiaozi has not yet dissipated, and the second is that Zhang San is now an exporter of copper and copper coins, and the paper currency of copper coins will do more harm than good to him.

Because now the Ryukyu subject state has been upgraded to a vassal state like Qi and changed its name to Qi, then the words Ryukyu on the previous currency need to be modified, and the new currency needs to be redesigned and cast, and these things have to be Zhang San's final idea.

However, it is still very troublesome to change it, so Zhang San plans to directly mint Han Yuan and Han coins, and now the name is the coins of the Han people, and the next step is where Zhang San will set the capital after occupying Beiping, and then the newly established country will be named Dahan.

In this way, there is no need to recycle and reprint the currency in the future, Zhang San attended the meeting this time to look at the template of the new coin, and finally determine the place where the new currency will be minted, and then there will be the first batch of silver and Han Yuan to be issued.

In the end, after calculation, Zhang San decided to put the first batch of 100 million taels of silver and 100 million yuan into the market, first let everyone be familiar with the currency, and then slowly increase, in fact, the amount of 200 million is really a lot, converted into the Great Song Dynasty copper coin, nearly 600 million yuan, which is expected to be equivalent to one percent of the currency in circulation on the market.

In the past, Zhang San was also worried that the currency reform would face the risk of being run, but with the increase of national strength, now Zhang San is not worried about this problem at all.

Now Zhang San's treasury has more than 400 million taels of silver, and more than 100 million taels of gold, which is completely capable of dealing with the run of any force, and there is no such force that can run on it.

Now after the copper coin is pegged to silver, in the exchange of Song coins, it completely avoids the change in the value of the currency Some people are opportunistic, and after the new currency is issued, it will be parallel to the old currency, and the value of the old currency is the same as the new currency.

Economics is a new discipline for Zhang San and his subordinates, everyone is crossing the river by feeling the stones, and Zhang San does not dare to take too big steps, for example, Zhang San used to read newspapers, and the reserve of paper money only needs one-fifth.

Just like Zhang San issued a 100 million yuan banknote, he only needed a reserve of 20 million taels of silver, but Zhang San did not do this, and still insisted on a one-to-one reserve, as for the future after the country's prosperity and stability, this method can be properly considered.

The new mint will be located near Tai'an, Shandong, where a medium-sized coal mine has been discovered, where there is no need to worry about raw materials, and the mint factories in other regions will be closed one after another, and the country will maintain three to five large mint centers.

After all, the right to mint coinage is a major national matter, or put it under your nose to be a little more assured, after participating in the coinage meeting, Zhang San went to participate in the construction and design of the new embankment of the Yellow River.

After an investigation by the Ministry of Water Resources, on the basis of repairing the existing embankment, the Ministry of Water Resources proposed to build a new embankment, because according to Zhang San's requirements, the design of 50 years or even important river sections should reach the level of once in a century, and the current embankment simply cannot meet the demand.

Because the current promotion was urgently built according to the flow direction of the Yellow River at that time, and later strengthened on the original embankment, there is a problem, that is, the widening of the river runoff during the flood season is not taken into account, and the reserved riverbed is too narrow to be used.

Therefore, instead of continuing to increase the height and width of the existing embankment, it is better to expand the width of the river, and after calculation, the height of the embankment can be reduced by one-third as long as it is moved back one mile, and the amount of earthwork saved can be used to build a semi-existing dam.

For such a huge project for the benefit of future generations, Zhang San of course hoped that the design would be as full as possible, so after the proposal to rebuild a dam came out, a new question arose, that is, whether to return to the river.

Since it has been rebuilt, some people have proposed to simply rebuild it on the original Shandong River and directly let the Yellow River return to the river, so as not to reverse the Yellow River back to the ancient road, but most of them feel that since it has flowed north, it should be built on the Yellow River flowing north, so that it is convenient to defend.

In the end, Zhang San did not hesitate to support the plan of the north stream, because Zhang San knew that there would be a serious shortage of water in the north, although the Yellow River was often cut off in later generations, but there were times when the water was abundant, and it was better to have more than less.

Moreover, Zhang San plans to set the capital in Beiping in the future, so the northward flow of the Yellow River is not equivalent to adding a natural waterway there, which can save a lot of time and resources for the capital's water and grain transportation.

Due to transportation restrictions, there are only more than 200,000 slaves on the construction site at this stage repairing the river, and in the next stage, there will be 2 million slaves divided into more than 10 sections. Each section will be divided into ten battalions, each with 20,000 slaves.

The location of these slave camps also needs Zhang San's final nod to be built, and a hundred slave camps still need a hundred battalions of soldiers to guard, which is 100,000 soldiers, and it also needs the cooperation of the military.

In addition, since the expansion of Heti, the villages around Heti will definitely have to be relocated, and these migrations involve more than 100,000 people, and they will eventually be sent to the Americas, so it is necessary to do a good job of mobilization.
