The precious metals such as gold and silver were not circulating currency in the Tang Dynasty. The silver standard era would not gradually appear until the Song Dynasty, and the real formation was in the distant Ming Dynasty.

Although it is not a circulating currency, the value of gold will not deteriorate at all. Anyone will recognize this thing if it is used. Yan Fei is planning to exchange gold for money.

Although other things in the cargo box are not valuable, they are materials that cannot be provided by this era before the time and space channel is reopened. Although gold is valuable, it is also owned in this era. At this time, it is naturally necessary to exchange gold for money first.

A few years ago, Li Yuan issued the Tang Dynasty's standard copper coins Kaiyuan Tongbao. Because it was related to his own face, Li Yuan's Kaiyuan Tongbao was well-made and very good. Each copper coins were standard one qian, and ten qian was one liang. The usual money was 1,000 qian and four liang. Because one jin in the Tang Dynasty was 16 liang.

The eight hundred guan coins that Yan Fei exchanged for two bottles of human heads and horses before filled a whole cart with a full chariot. The copper coins were very heavy.

Due to the chaos in the world, many people are displaced, and the constant wars are constantly happening all day, which directly leads to the reduction of production of various products and insufficient materials. The corresponding prices are also followed by the trend. Of course, this price refers to physical goods, such as food and cloth.

Although Guanzhong has abundant resources, it still needs to import a large amount of grain cloth from outside. With the invasion of the Turks, the price of grain rose rapidly, and the price of rice had exceeded 500 cents. One stone of ten dou, and one stone of grain was more than five jin of copper coins, which would force people to death.

It was also because of the Turkic invasion and the turmoil in the court after the Xuanwu Gate that a large number of rich people fled to the south of the Guandong and Jiangnan. The result was that the land and housing prices fell. Yan Fei chose a good opportunity to buy a manor outside the city. However, Changsun Chong took advantage of it. However, this advantage was not easy to make. Yan Fei was actually a very stingy person, and one day he would let Changsun Chong spit out the capital and profit.

In addition to food, cloth is also used to make clothes. A piece of cloth is four meters long, one foot and eight inches wide, and weighs about twelve taels. Such a small amount of cloth can't be used to make a few pieces of clothing. Moreover, the quality of cloth in this era is not good, and the clothes are damaged very seriously.

At this time, the value of a piece of cloth was more than 500 cents. The first two of the four essential daily necessities of food, clothing, housing and transportation were so high that the direct result was life difficulties.

Although valuable items such as gold and silver are not circulated, they are still used. They are usually used by the emperor as rewards, or by merchants as bottoms. However, because the quantity is small, the value is very high.

Yan Fei pulled out his travel bag, reached out and threw more than a dozen heavy gold nuggets into the bag. He closed the cabinet door and zipped it up and left with the bag.

This back and forth run made the Huang Pima very tired. Fortunately, Yan Fei also knew a lot about this. He controlled his speed and horsepower and did not run desperately to make the horse sweat and lose its use.

‘Ba!’ Back in the manor, Yan Fei threw a gold nugget weighing one kilogram and threw it into the butler’s arms. “Go to the city to exchange for copper coins, grain and cloth, each accounting for one-third.”

The housekeeper had seen gold when he was doing things with noble people, but he had never seen such a heavy gold nugget. This was too scary.

According to the court's regulations, the exchange ratio between gold and silver was ten to one, and silver was always worth copper coins. However, this was just the superficial price. Because gold and silver were sparse and the value was always high, the actual exchange ratio was very high. At this time, one or two silver taels were enough to exchange for 1,600 coins of copper coins.

It is recorded in the New Book of Tang that the ten coins of Kaiyuan Tongbao are 2. In other words, the weight of ten coins of Kaiyuan Tongbao is one liang. It is converted into a modern unit, which is 425 grams. The gold thrown by Yan Fei weighs one kilogram, which is 25 liang. It is converted into a silver price, and it is 76 jin when it is converted into a copper price.

The rice price in Chang'an before Xuanwu Gate was actually not too high, roughly around a hundred ciders of rice. Although it is not cheap, most people will not starve to death after eating.

But after Li Shimin launched the Xuanwu Gate Incident, the rice price in Chang'an City soared like a somersault. When the news of the Turkic invasion came, the rice price soared to the sky. When the Turkic army arrived at the banks of the Weishui River, the rice price in the city was even hyped up to the point where the rice price in the city exceeded 1,000 liters.

As for those masters who have promoted grain prices, they are all families that have been passed down for many years and are known as scholarly families.

With their promotion, a dou of rice is more than once a day, and a dou of rice is ten liters, which is less than ten kilograms in the modern world. This is equivalent to selling less than one kilogram of rice for a hundred cents. Most people in Chang'an City in this era definitely earn less than one hundred cents a day. But they all have family members with old people and young children to eat.

He has a very strong personality and always uses a knife instead of a mouth to deal with the enemy. The only reason why Li Shimin, who has not even let his brothers go to Jie Li to seek peace was that the internal turmoil was too great. He really couldn't fight. The people were almost forced to death by the price of food. How could they fight?

However, with Li Shimin's strong personality, those who take the opportunity to hoard food and provoke food prices will definitely not have a good ending.

After Li Shimin and Jie Li killed the Baima to form an alliance and signed the Weishui Alliance, the grain prices fell rapidly and had already fallen to 500 mug of rice. And they would definitely continue to fall in a few days.

Judging from the current grain prices, Yan Fei gave one-third of the gold that he bought was able to buy about twenty stones of grain.

"I dare to ask my husband." The housekeeper did not go directly to the city to exchange money for food, but instead asked respectfully with gold nuggets in his arms, "Would you like to buy millet, wheat, yellow rice or millet."

"Huh?" Yan Fei was stunned by the question. In his impression, grain was rice. Even in the time and space of the Song and Ming dynasties, let alone the modern world. "What is millet, what is wheat, what is yellow rice and what is millet? What is the difference."

"Reply to your words." The housekeeper was puzzled in his heart that Yan Fei could not tell the difference between food, but he soon gave Yan Fei a respectful popular science.

Milk is corn, which is commonly referred to as millet. It is yellow in color and is suitable for cooking porridge. Everyone may know millet porridge. Wheat is noodles, ground into flour and made flour. Yellow rice is millet and made into big cakes, but it will irritate the throat. As for millet, it is rice rice.

Different grain crops have different prices. For example, rice is now 500 cents per dou, which is the standard price. And corn is much cheaper, and you can buy one dou for just over 300. The price of millet is similar to corn. Wheat is a little more expensive than rice.

"Yeah, I understand." Yan Fei hadn't paid attention to these before, and now he nodded slightly after knowing it, "You just look at buying."

Rice and wheat were eaten by rich people or noble people at home. Ordinary people and servants mainly used corn and millet. In this feudal era, even grain was divided into high and low. After all, rice and wheat tasted good, while corn and millet were a little worse.

However, what surprised Yan Fei was that the matter was not over yet.

"Mr.," the housekeeper continued to say, "The cloth, silk, hemp is different, and there are all kinds of silk, silk, satin. The government has the value of the silk for the goods, so I wonder how much should I buy?"

One of the most prominent features in the feudal era is that the shortage of various materials. Neither food cloth nor copper, iron and precious metals could meet the demand. It was not until the outbreak of the industry that this shortage of goods that lasted for thousands of years was alleviated.

Because of the lack of copper, the amount of copper coins is very small. Otherwise, it would not appear as five or ten cents. So at this time, the government used silk with large output and high demand as supplementary materials for currency. In a word, silk is used as money.

Yan Fei said that he would buy cloth and silk, but the housekeeper couldn't figure out whether he wanted to buy clothes or silk for money or just ask clearly.

The wealthy and noble families naturally have silk and satin, and it would be nice for ordinary people and servants to wear linen and silk. How much these things should be bought as the owner Yan Fei.

To be honest, Yan Fei did do his homework before, and he had read some of the various materials from all dynasties. But he really didn't know about these things.

"You can do the specific matters by yourself." Yan Fei thought about it and handed over the matter to the butler to handle it. Since he didn't understand, he would leave it to the person who understood it. Even if he messed up, it would be just a gold nugget.

When the butler hurriedly drove the car to Chang'an City, Yan Fei also left the manor and wandered around the nearby village.

This is a village outside Chang'an City, and Chang'an is the core of the entire Tang Dynasty. Everything you see here can at least represent the situation in most parts of the Tang Dynasty today. Because if you can't even have a village under the feet of the emperor, the place thousands of miles away will definitely be even worse.

This village is not big, and it doesn’t take much effort to walk from beginning to end. The whole village gives Yan Fei the impression of being poor.

The dozens of families in the village are all thatched huts, none of which are brick and tile houses. They are all that kind of adobe houses, with roofs covered with thatch. A hole in the south wall is considered a window to be a home. Occasionally, several families have pigpens and chicken coops, which is considered a wealthy family. As for large animals such as mules, horses, and oxen, Yan Fei walked around the village for a long time but didn't see them.

As for the roads in the village, there are simply no roads. They are all dusty and bumpy paths. Once it rains, mud and water can flood your ankles.

Finally, there are people. Most of the people here are wearing patched linen clothes, and most of the feet are straw sandals, but a few of them have cloth shoes. They have dark complexion and rough skin, and they are typical farmers with a face facing the loess and back facing the sky. Moreover, there are not many young people in the village, most of them are elderly people and children.

"Didn't it mean that the soldiers of the government are all small landlords and self-cultivated farmers selected from various villages?" Yan Fei walked to the entrance of the village and looked at the village in confusion. "Who can buy armor, armor, ordnance, mules and horses in such a poor place? Just kidding."

Yan Fei's idea was not wrong. Although the burden on the government soldiers was very heavy in the early Tang Dynasty, it was also a rare opportunity for ordinary poor families to enter the government and enter the upper class by relying on military merits. Therefore, many people still competed to become government soldiers.

The owner of the village was mixed with Li Yuanji, and after Xuanwu Gate, he brought a group of soldiers from the village to the end. Later, Jie Li invaded, and most of the young people in the village were summoned into the army, but they were not soldiers but strong men in the civilians.

Only when these people make contributions on the battlefield can they have the opportunity to change their identities and become soldiers. The battlefield that can make the civilians make contributions will collapse and collapse. At that time, there will be no chance to make contributions, and it will be too late to escape.

Fortunately, Jie Li had retreated, and these civilians would not be able to go home soon.
