Wang Haichao took the piece of colored paper, the printing is very exquisite, there are several prints on the front and back, the title is "Huainan - Dongdu - Shangdu boundary", the following is the year name Xingyuan a certain year and a certain month and day, and then the next is stamped with the seal of "Huainan Yangzhou Metropolitan Governor's Mansion", and then the back is the drawing of Shun as a five-stringed pire singing the south wind, and there are denomination numbers and the blank of the requester's payment.

"This, this is flying money and exchange!" Wang Haichao lost his voice.

"That's right, in fact, it's more straightforward, it's called a coin." Gao Yue replied.

Of course, at this stage, the currency is only a commercial bill.

The monetary economy of the Celestial Empire was not actually developed in ancient times, and commercial bills of exchange first appeared in the Babylonian era, which came into being in the context of the flourishing Mediterranean trade, but the Celestial Empire was a bumpy road, and the first peak period of its currency issuance was in the Han Dynasty, but after the fall of the Han Dynasty, the society took the initiative to regress to the era of physical economy.

The second sub-peak is the Sui and Tang dynasties.

Why is it a sub-peak? Because during the Tang Dynasty, although currency has penetrated into all aspects of society, the whole country still has a strong physical economic color. It was not until Yang Yan's two tax laws were implemented that the economic model of the Celestial Empire had earth-shaking changes, and there was a core criterion of the two tax laws, that is, all taxes must be paid with money (or converted into money), that is, the copper money currency standard, and monetary finance. Then, after the Middle Tang Dynasty, there was an era of monetary economic explosion, which lasted until the Song Dynasty.

During the Tang Dynasty, the country did not lack cloth and rice grain (Du Fu said that 'rice is fat and corn is white, public and private warehouses are abundant', and the physical goods are abundant, and even surplus), so the private money is very rampant, because everyone began to understand the benefits of money at that time.

But after the Anshi Rebellion, the Tang Dynasty had a period of time, which belonged to a serious "currency devaluation", popularly speaking, "money is not worth much", the reason is also very simple, the war directly destroyed Heshuo, Henan and other regions, and a large number of young and strong laborers were forced to join the army, production was sluggish, rice was gone, cloth was gone, so the real thing was very expensive all of a sudden (Du Fu 'how could I hear a silk straight ten thousand money'), so that Emperor Daizong Xuan Guo Ziyi went to Beijing to comfort him, not to give money, but to give Guo two hundred silk silk.

Then to the two tax laws, the state through the compulsory policy of "tax payment", the world of money into the hands, the situation immediately changed, the market for circulation of money became less, money more and more expensive, while grain and cloth are cheaper and cheaper, merchants are inconvenient to buy and sell, agricultural workers are also very difficult to live, the formation of a "deflation" that lasted for decades, that is, money shortage.

In the past, the currency depreciated, and the Tang Dynasty wanted to add a large number of smelting furnaces and mint more money, hoping to exchange more physical goods.

Now deflation, the Tang Dynasty still has to mint more money to put into circulation and alleviate the money shortage.

But the Tang Dynasty also minted about 200,000 yuan a year, which really couldn't meet the demand, and finally made a killing move - Tang Wuzong destroyed the Buddha, and melted many Buddha statues at one time to issue new money (the refined copper proposed by a big Buddha statue can create two or three hundred million copper coins), so as to solve this problem.

However, the good times did not last long, and after Tang Xuanzong, the "good emperor of five generations", succeeded to the throne, he once again believed in Buddhism, and returned the bronze to the furnace to make Buddha statues......

Then there is the second peak, to the founding of the Great Song Dynasty, Yunkai Yueming, the first good thing is to inherit the five dynasties and ten kingdoms, the feudal towns and the secession of the regime of the scavenging technique intact, and even integrate and renovate the patterns, so the Great Song Dynasty may be the only dynasty in the history of the Celestial Empire that has not implemented the "light and thin endowment" in the early years of the founding of the country (1) (if there are students who disagree with this, you can directly refute me), two taxes, miscellaneous collections, and the prohibition of the goods of the mountains and seas, as well as commercial taxes, mining and smelting money, selling official beards, selling degrees, Speculating on official land, there are many tricks, so the heavier the tax, the more money is needed, the Great Song Dynasty played with his life to mint money, and tried his best to mint two or three million yuan a year, but it was not enough, so he began to engage in paper money, and the initial paper money was OK, but after all, the Song Dynasty was a "exhausted previous dynasty to accumulate wealth", and its additional currency and paper money were basically not used in the growth of production (2), but were swallowed up by the three redundancies without limit, Wang Anshi's change was intensified, and the purpose was to loot more money into the hands of the emperor. Therefore, the Song Dynasty was still tormented by the shortage of money and the depreciation of paper money, and it was even more fierce in the Cai Jing era, and the fiscal policy of "weak outside and inside" (playing hard to loot from the place and concentrate on the emperor) reached its peak.

Facts have proved that there is no good end to accumulating money from the people.

Therefore, Gao Yue was reluctant to hand over the money collected from the Huainan two taxes to the imperial court, because this would make the money hoard in Beijing, and the entire Jianghuai would be even more short of money, and the money shortage would hinder the transfer of commerce and trade, and it would also cause the grain to hurt the peasants and the cloth to hurt the workers.

He simply used the Cao River to ask the merchants of Huaiyang to sell the goods to the Jingshi, and after selling the money, he sent them directly to the Jinju Yuan, and received the same amount of "coins", that is, bills of exchange, and then returned to Yangzhou with the coins to receive cash.

In this way, the money in Beijing is actually transferred within Beijing, and the money in Huainan is still transferred in Huainan.

Gao Yue also set up a special money exchange agency in this regard, and he took part of the cash in this year's two taxes into shares, plus the wealthy businessmen of Xingyuan, Jiannan, Kuifu, and Huainan, as well as the funds raised by Xingyuan Huguo Temple, to establish a "convenient money warehouse".

In kind, that is, cloth and rice, some of which Gao Yue left in the Changping warehouse or military treasury to be responsible for disaster relief and military rations, or sent to brew wine, and the rest were also entrusted to merchants to sell to other places, buy low and sell high, in exchange for cash.

In the end, in front of the backyard of Yangzhou City, one by one into the Feng ship set sail, the ship was full of loads, in addition to the Hudou rice offered on the regulations, it was Huainan's specialty tea, medicine, woodware, jewelry, as well as silk yarn, wine, porcelain, etc., which were transferred from the south of the Yangtze River.

This is less like a tax-paid fleet and more like a large merchant fleet.

Xuanwu Army since Dong Jin took charge, the style is still greatly improved, Dong Jin is the minister of the imperial court, after he arrived in addition to stabilizing the people's hearts, and then he hired soldiers and people, dredged the Bianshui channel, and abolished the Daitang along the road, so when Yangzhou's fleet arrived at the Bianzhou Transfer Hospital, the entire military city was a sensation.

Many people, soldiers, and women flock here to form a natural grass market, and the brocade of Yangzhou, the silk of Runzhou, the paper of Changzhou, and the porcelain of Suzhou are particularly popular, and there are also many rich and noble families who are eager to try and are particularly interested in the jewelry made by the Hu people.

Even Luo Zhen was on a high-rise building and knew that the "Huaiyang goods" were coming, so he asked the maid to buy a few pieces of good color silk, a few strings of tea, and some paper.

Soon some of the goods were sold, in fact, before coming to Bianzhou, a lot of them were sold in the key places of Chuzhou and Sizhou.

At the Yin of the River, the entire caravan changed to ships entering the Yellow River, carrying money and remaining goods, and set off for Chang'an City.
