NT digital currency

1. There are thousands of digital currency exchanges all over the world. In order to meet the needs of investors, the proct experience and main business of different platforms are also different. Without understanding, many investors who have just entered the circle may be fussy. At this time, we might as well communicate more with professionals in the circle. We must choose a formal digital currency exchange. We'd better choose a digital currency exchange that is developing and growing, which is trustworthy and has certain strength, such as fire currency and man currency.

In 2016, the global ranking of virtual currency is respectively as follows:

< H2 > bitcoin, Leyte, Ecuadorian, reborn, bitstock, doggy, Diablo, futurecoin, diandiancoin and Xingxing < H2 > first place: bitcoin

since its release in 2009, bitcoin has become the most well-known virtual currency. This virtual currency was developed by indivials or organizations under the pseudonym of "Nakamoto Tsung" (whose real identity has always been unknown), and is mainly used by online merchants. However, in recent years, some small physical merchants have begun to accept bitcoin payment. Through complex algorithms and a large number of computing resources, users can obtain bitcoin through "mining". Of course, they can also purchase bitcoin through exchanges or services like bitinstagnt and coinbase. The total amount of bitcoin that can be mined is about 21 million, while the current mining amount has exceeded 11 million. Bitcoin has attracted the attention of Western Union, MoneyGram and paypal. It is reported that these services are evaluating whether users are allowed to use bitcoin on their respective platforms

< H2 > second place: lightcoin

lightcoin is inspired by bitcoin (BTC) and has the same implementation principle in technology. The creation and transfer of lightcoin is based on an open source encryption protocol and is not managed by any central organization. Lightcoin aims to improve bitcoin. Compared with bitcoin, lightcoin has three significant differences. First, the lightcoin network can process a block every 2.5 minutes (instead of 10 minutes), so it can provide faster transaction confirmation. Second, the lightcoin network is expected to proce 84 million lightcoins, four times the amount of money issued by bitcoin network. Thirdly, the scrypt encryption algorithm first proposed by Colin Percival is used in lightcoin's workload proof algorithm, which makes it easier to mine lightcoin on ordinary computer than bitcoin. Each Leyte coin is divided into 100000000 smaller units, and the third place is defined by eight decimal places: Ecuadorian currency. In December 2014, Ecuador launched the "electronic currency system"

Ecuadorian currency, or EDC, which is a digital currency issued by the Central Bank of the government of Ecuador. In December 2014, the Ecuadorian market was launched, In 2015, the number of Ecuadorian currency members reached 500000, which will be recognized and sought after by investors after launching the European market and Asian market in 2015, and achieve a complete success. It will strongly launch the Chinese market at the end of September 2016, and will issue a limited number of 50 million pieces in China, which has a strong scarcity! This is an international hot topic with a wide range of admirers in the world. Historical currency is a kind of P2P digital code. Ecuadorian currency is not issued by a specific monetary institution. It is generated by a large number of calculations based on a specific algorithm. Ecuadorian currency economy uses a distributed database composed of many nodes in the whole P2P network to confirm and record all transactions

decentralized encrypted digital currency has no issuing institution, and it does not belong to any indivial, institution, bank or country, so it cannot be shut down. Ecuadorian coin mining machine is mining 24 hours a day, and the extracted Ecuadorian coin can be traded through the trading platform to obtain profits. Ecuadorian coin mining refers to the scrypt algorithm, The process of collecting and sorting the transaction information that has not been recognized by Ecuadorian currency in the past period of time, broadcasting to all nodes in the whole network, and finally being recognized by all nodes and getting Ecuadorian currency. Mining is the only way to issue new currency, which plays an important role in issuing new currency, maintaining Ecuadorian payment function and ensuring system security

Like bitcoin, XRP is a digital currency based on Mathematics and cryptography. However, unlike bitcoin, XRP has no real purpose. XRP has the main function of bridging currency and ensuring security in ripple system, among which the function of ensuring security is indispensable, This requires that all gateways participating in this protocol must hold a small amount of XRP

in theory, gateways don't need to buy many xrps, and their prices are very cheap. One XRP is only 0.4 cent (as of March 14, 2015, its price has risen to about 1 cent). Like bitcoin, the number of xrps can not be "over issued" (the total number is 100 billion), but since a small amount of xrps will be destroyed in each transaction, it means that the number of xrps will graally decrease. If ripple protocol can become the global mainstream payment protocol, the gateway's demand for XRP will be more extensive - the demand is strong but the quantity is decreasing, which will lead to the appreciation of XRP

< H2 > fifth place: bitstocks

bitstocks adopt an architecture similar to bitcoin blockchain. In the bitcoin blockchain architecture, each transaction data must be written from the previous transaction data, and new outputs are generated almost at the same time to be used for future transaction data writing. Each stroke can only be used once under certain conditions. Each transaction output contains the balance information of bitcoin, proving that it can be used for future transactions. In order not to proce bitcoin out of nothing, the write value of the transaction must be greater than the output value

bitcoin uses a simple script language to evaluate the situation that the balance is insufficient when the transaction is output; However, most of the transaction output only needs the holder's encrypted signature

< H2 > sixth place: dogcoin

dogcoin, some people call it "dogcoin", was born on December 8, 2013, based on the scrypt algorithm, is the second largest virtual currency in the world after bitcoin in the number of users [1]. Digital currency is a global currency initiated by non-governmental organizations. It does not belong to a certain country, but belongs to the whole mankind. It has the advantages of fast global transfer. For example, it can remit money from China to the United States in a few seconds, with low cost, and the total amount will not be increased at will like legal money, so the total amount is relatively stable

after the launch of dogcoin system, e to the help of reddit (the doge content on this website overflows horribly), the traffic shows an explosive development. However, in two weeks, dogcoin has launched a special blog and forum, with a market value of 100 million as of June 9, 2015. Because there is no pre dig, dog coin distribution is fair, charity, reward culture is popular, and user development is amazing and rapid. On June 9, 2015, the number of Dog Coin client addresses was 1.6 million, more than five times that of Wright coin; The number of active client addresses is 196000 in bitcoin, 83000 in dogcoin and 11000 in lightcoin; There are more than 150000 foreign Twitter users, 1.7 times of bitcoin and 6 times of lightcoin. Facebook likes are the same as bitcoin, far more than lightcoin [2]. The daily real transaction volume has been ranked in the top three of virtual currency for a long time, which is still not as good as the result obtained before the big platform [3]. The biggest value of the enterprise Internet era is the huge number of users. It took one year for the user base of dogcoin to reach one third of the number of bitcoin users, and the seventh place is lightcoin, which is four times the number of bitcoin users. A special solution is one of the infinite (in fact, bitcoin is finite) solutions that can be obtained from the equations. Every particular solution can solve the equation and is unique[ 8] In the metaphor of RMB, black money is the serial number of RMB. If you know the serial number of a note, you have the note. The process of mining is to constantly seek the special solution of the equation system through huge amount of calculation. The equation system is designed to have only 22 million special solutions, so the upper limit of bitcoin is 22 million[ 8]

to mine the dark coin, you can download the special dark coin calculation tool, register various cooperative mine pool websites, fill the registered user name and password (miner user) into the calculation program, and then click the operation to officially start. After completing the installation of the darkcoin client, you can directly obtain a darkcoin address. When others pay, you only need to post the address to others, and you can pay through the same client. After installing the Black Coin client, it will distribute a private key and a public key. You need to back up your wallet data containing your private key to ensure that your property is not lost. Unfortunately, if the hard disk is completely formatted, the personal dark coin will be completely lost

3. Now digital currency is not legally traded in China.

4.

CNY is the legal tender of the people's Republic of China and the standard currency symbol of RMB in the world monetary system, which is simplified from (Chinese yuan)

the unit of RMB is yuan, and the subsidiary units of RMB are Jiao and Fen. One yuan is ten Jiao, and one Jiao is ten Fen. The first letter of the alphabet of RMB is capital Y with two horizontal lines, that is "&#"

on January 20, 2016, the people's Bank of China disclosed at a meeting held here that it will strive to launch the digital currency issued by the central bank as soon as possible. The meeting held that under the current new normal of China's economy, it has positive practical significance and far-reaching historical significance to explore the digital currency issued by the central bank

extended information:

issuance history

RMB is issued by the people's Bank of China. Except for 1, 2 and 5 coins, the first set of RMB, the second set of RMB and the third set of RMB have been withdrawn from circulation, and the fourth set of RMB has been withdrawn from circulation since May 1, 2018

RMB circulating in the market is the fifth set of RMB; Banknotes in circulation are: 1 jiao, 5 jiao, 1 yuan, 5 yuan, 10 yuan, 20 yuan, 50 yuan and 100 yuan; There are 1 yuan, 5 cents, 1 jiao, 5 fen, 2 fen and 1 Fen in coins

among the five sets of RMB displayed in the China Coin Museum, different from the last four sets, the six characters of "people's Bank of China" and the denominations of Chinese characters on the first set (except the 1953 version of 5000 yuan Weihe bridge design voucher) are arranged from right to left

In 1952, when Chairman Mao reviewed the voting version, he proposed that the row names of RMB should be arranged from left to right, so since 1953, the row of "people's Bank of China" on RMB has been changed from left to right

5. Virtual currency only bitcoin can be traded in a few exchanges. It seems that only four exchanges in the world recognize it.

the others are liars.
the Chinese government denies the legality of all virtual currencies (including bitcoin). Commemorative currency only recognizes the legality of the central bank, and everything else is illegal

6.

1. Different

CNY (Chinese yuan) is the currency symbol assigned to China by ISO, and the Chinese name is RMB. The abbreviation of RMB is the combination of the initial letters of its Chinese Pinyin, that is, RMB & #;, But its standard currency symbol is CNY

2, different use scope

CNY is the only standard symbol of RMB in international trade. Now it has replaced RMB; It is used for foreign exchange settlement and domestic settlement. However, when it is used for domestic settlement, it is RMB & # 165 without confusion; It still works

3. Different in nature

RMB is the abbreviation of RMB and CNY is the standard currency symbol of RMB. Generally speaking, RMB is the saying of China, while CNY is the saying of international currency

7.

The abbreviation of RMB is CNY, e (Electronic) means electronic, so the Chinese digital RMB is e-cny

China's digital RMB is actually the electronic version of RMB, and the digital currency (not yet issued) launched by the people's Bank of China has national credit endorsement and legal compensation, so the currency value will be more stable. In the use scenario, the digital currency issued by the central bank does not pay interest, and can be used in small, retail and high-frequency business scenarios

extended data:

up to 2020, the most commonly used banknotes are banknotes. The denominations of RMB banknotes are 1 jiao, 5 jiao, 1 yuan, 5 yuan, 10 yuan, 20 yuan, 50 yuan and 100 yuan; The denominations of the coins are 1, 2, 5, 10, 50 and 1 yuan. Conversion relationship, 1 yuan equals 10 Jiao, 1 jiao equals 10 Fen

the fifth set of RMB used by users is mainly issued in 1999, 2005, 2015 and 2019. The first set, the second set and the third set of RMB have been withdrawn from circulation, and the fourth set of RMB will stop circulation from May 1, 2018 (except 10 cents and 50 cents notes and 50 cents and 1 yuan coins)

8. One or two silver is worth about 150-220 yuan in the middle and late Qing Dynasty; In the middle of Ming Dynasty, it was worth 600-800 yuan; In the middle of Northern Song Dynasty, 600-1300 yuan (or 1000-1800 yuan); 2000-4000 yuan in the prosperous Tang Dynasty

9. In ancient times, silver was used as a unit of money. How much was one or two silver? There are many monetary units in ancient China, which are different from Dynasty to Dynasty, especially before Qin and Han Dynasties. Here we only discuss three basic units: a coin made of one article (i.e. a standard square hole copper coin) one or two silver or one or two gold units. Although different dynasties and dynasties differ, at least after the Tang and Song Dynasties, there is little difference, so we can get more stable and reliable data. The exchange rate between copper, silver and gold, just like the current foreign exchange price, often changes. It is not so clear that one yuan equals 100 points. According to the following description: "the price of gold and silver rose from 1:8 around 1600 to 1:10 in the middle and late 20th century, and doubled to 1:20 by the end of the 18th century." It is known that 1 liang of gold can be exchanged for 8 ~ 11 liang of silver. Another: "in the early years of Daoguang, one or two silver coins were exchanged for a crane, that is, one thousand Wen; By the time of the Opium War in the 20th year of Daoguang, one or two silver coins could be exchanged for 16700 RMB. Since Xianfeng, the price of silver has soared, and one or two silver coins can be exchanged for as much as two thousand two hundred and three hundred Wen. " It can be seen that under normal circumstances, one liang of silver can be exchanged for 1000-1500 Wen copper coins. In ancient times, one Guan coin or one Diao coin is 1000 Wen. 2. Metal price because the money made of gold, silver and copper is valuable, and theoretically, the value of money should be equal to the price of metal, so we can answer the question of "how much is one or two silver" through the current price of metal. In the Tang Dynasty, Kaiyuan Tongbao Tongqian had a diameter of 8 cents, 10 of which weighed 1 liang, and a thousand characters weighed 6 Jin and 4 liang; During the reign of emperor Shun of the Qing Dynasty, each copper coin weighed one and two cents and five percent, and then increased to one and four cents, which meant that each thousand Wen weighed eight Jin and twelve Liang. Although the ancient "two" weight units are different, they are about 40 grams, while the "Jin" is about 700 grams. The average weight of each coin is 5g. At present, the price of gold, silver and copper (RMB) is as follows: Gold: 100 yuan / g, silver: 2 yuan / g, brass: 0.02 yuan / g. the calculation results are as follows: 1 two gold: about 4000 yuan, 1 two silver: about 80 yuan, 1 copper coin (1 coin): about 0.1 yuan. 3 grain price is directly measured by grain price in many historical monographs, Although it is not very accurate and objective to consider the grain price alone, it should be an extremely important reference. Xiaolin found the following records on the Internet: "in the first half of the 15th year of the reign of Emperor Guangxu, the grain prices of shuntianfu, damingfu and Xuanhua in Zhili Province were calculated on the basis of millet, sorghum and corn, On average, one hundred and twenty-four cents and six cents per warehouse. " According to the calculation of 1 stone = 100 Jin = 70 kg, and the price of grain is 2 yuan / kg, we can get the following average value: 1 liang of silver: about 170 yuan, 1 copper coin (1 paper coin): about 0.2 yuan. 4 Conclusion: according to the above calculation, considering that the price of 1 gold is more stable than others, we should focus on reference 2. Now silver has been used as an instrial proct, Therefore, the reference value of silver price is relatively low at present. 3 e to the rapid development of agricultural technology, the relative price of grain is much cheaper than that in ancient times. 4. Respect the exchange ratio in ancient times. 5. Rounding up the whole number is easy to convert and establish perceptual knowledge. Therefore, the author suggests that the following conversion system should be adopted when meeting the monetary units in ancient times in the future, It's convenient and has a feeling: 1 liang of gold = RMB 2000 yuan = 10 liang of silver 1 liang of silver = RMB 200 yuan = 1000 Wen Qian = 1 Guan (Diao) Qian 1 Wen Qian = RMB 0.2 yuan in addition: 1 Shi Mi = 1 liang of silver statement: the above conclusion is not an academic point of view, it is only used for conversion when people watch ancient costume TV dramas and martial arts novels. 5 verification, the following provides some ancient data, which is convenient to verify the conversion method given by Xiaolin, and improve the perceptual understanding: in the Tang Dynasty, the monthly salary of Jiupin official was 5 stone meters = in the Tang Dynasty, the monthly salary of junior civil servants was 1000 yuan; The annual salary of liupin officials in the Qing Dynasty is 45 liang of silver = bureau level cadres in the Qing Dynasty, with an annual salary of 9000 yuan; Three years later, the magistrate of the Qing Dynasty, a hundred thousand snowflakes of silver = those officials, there are not tens of millions in that family? In the early years of the reign of Emperor Qianlong, it took 13120 liang of silver to donate a Daotai, which cost 2.7 million yuan to buy a Dangdang of a department level cadre with a clear price tag. reference material: http://219.223.108.19 :1200/show.aspx?id=126&; cid=59 2\ There were many dynasties in ancient times. The value of silver varies from Dynasty to Dynasty. In the Northern Song Dynasty, the purchasing power of ancient gold, silver, copper and other currencies has always been an interesting topic. This gossip water margin also transforms the currency of the Song Dynasty into today's RMB in line with the modern context. Master Wuzhai is not an expert in the study of currency in Song Dynasty. It is impossible to make a complete and accurate conversion. Only a rough estimate can be given here, so that readers can have a basic concept. Generally speaking, gold, silver and copper coins (in fact, copper based alloys) were the main currencies in ancient China. The silver standard system in Song Dynasty is different from that in Ming and Qing Dynasty. It is copper standard system. Copper money is the main currency, and gold and silver are not used as currency. The basic unit of copper coin is "Wen" and "Guan" (Luo), which is consistent with 1000 Wen. In Song Dynasty, there were 800 Wen and 850 Wen when finance was tight. In addition, there are also discount two money, when three money, when ten money and other disguised inflation. For example, in the day when Yang Zhi killed Niu Er, Niu Er used to make Yang Zhi test his sword with three coins. As the name suggests, one coin is regarded as three coins. When Cai Jing was Prime Minister, he even offered ten coins. In order to simplify our calculation method, the owner of Wuzhai ignores these factors. When discussing ancient coins, we usually use such a hypothesis: 1 liang gold = 10 Liang silver = 10 Guan copper coins = 10000 Wen copper coins. Although the exchange rate of gold, silver and copper has been floating, this assumption is basically reasonable. Wang Zengyu, a contemporary expert of Song Dynasty history, once mentioned in the chapter 7 "overcoming Xianghan" in his new biography of Yuefei that the imperial court wrote to Yuefei: "fourth, pay 60000 stone meters and 400000 Guan for military supplies. At that time, gold and silver had not yet been used as independent currency. ". Thus, it can be seen that 400000 Guan copper coins in the early Southern Song Dynasty are equivalent to 100000 taels of silver and 5000 taels of gold, which basically conforms to the above hypothesis in the order of magnitude. To discuss the purchasing power of money, we must first mention the methods of two famous scholars. In his great history of China, Mr. Huang Renyu used the price of gold as the benchmark to calculate the value of copper coin today based on the assumption that 1 liang gold = 10 Liang silver = 10 Guan.. In his book "hidden rules", Mr. Wang uses both rice price and silver price as the benchmark and gives two figures. And I don't know. Mr. Wang focuses on the data converted from the rice price. Then, according to the two gentlemen's method, let's look at the Song Dynasty's yiguanhe today (October 2004) how much RMB 1) gold benchmark international price, gold price basically fluctuates around 400 US dollars an ounce. We'll take $400 an ounce. An ounce is 28.3 grams. In the Song Dynasty, one kilogram was 640 grams (the jiadiao bronze unearthed in Xiangtan, Hunan Province in 1975, weighing 100 kilograms and 64 kilograms). One kilogram has 16 Liang, so in Song Dynasty, one liang is 40 grams today. In this way, gold in Song Dynasty is equivalent to 565 US dollars, and in today's US dollar to RMB 8.23, it is equivalent to 4650 yuan. According to the assumption that 1 liang of gold is 10 liang of silver, that is, 10 Guan coins, the copper coins in Song Dynasty are equivalent to 465 yuan. 2) Silver benchmark international price, silver prices basically fluctuate around $6 an ounce. Similar to the conversion of gold price, one or two silver, that is, copper coin, is equivalent to 70 yuan. 3) The benchmark price of rice in Song Dynasty is 640 grams per catty. In the Song Dynasty, 1 stone is equal to 92.5 Jin. Therefore, a stone of rice has 59200 grams, or 59.2 kilograms. If we do not consider the special famine years or harvest years, the price of rice in the early Northern Song Dynasty was about 300 Wen to 600 Wen per stone, in the middle period (Renzong years), it was between 600 Wen to 700 Wen, and in the early Southern Song Dynasty, it was about 2 Guan. So it is reasonable to calculate about one Guan per stone ring the Huizong period in the late Northern Song Dynasty. If the current price of rice is 2.5 yuan per kilogram, 59.2 kg of Yishi rice in Song Dynasty is 148 yuan, that is to say, one Guan copper coin is 148 yuan. So far, we have three prices: 465 yuan for gold, 70 yuan for silver and 148 yuan for grain. Since China is not a major procer of silver, and the cost of extracting silver has been greatly reced after instrialization, the value of ancient silver must be significantly higher than the present value. Obviously, it is unreasonable to use today's silver price as a reference. It can be seen from today's silver price of $6 and gold price of $400 an ounce that one or two gold today can be exchanged for 66 taels of silver, while the exchange rate of gold and silver in ancient times is assumed to be 1:10. The output of gold is stable, and it is still regarded as an important hard currency reserve by all countries in the world today. So it's reasonable to use gold as a benchmark. In addition, although the rapid development of modern technology and Yuan Longping's hybrid rice have greatly improved the grain yield, today's population consuming grain has also increased significantly. According to the geographical records of the Song Dynasty, the population of the Northern Song Dynasty was less than 50 million, while today China has a population of 1.3 billion. Food is the first priority of the people, and the price of grain should still be an important benchmark. Therefore, the owner of Wuzhai took the average value of 306.5 yuan of 465 yuan of gold price benchmark and 148 yuan of rice price benchmark, and adjusted it to 300 yuan. Therefore, we have the following basic conversion: 1 Liang Jin = 3000 yuan, 1 liang yin = 1 Guan Tong Qian = 300 yuan, 1 Wen Tong Qian = 0.3 yuan. Take this exchange rate to see the salary of officials in Song Dynasty. According to the official records of the Song Dynasty, the salary of a prime minister in the Song Dynasty was 300 yuan per month, that is, 90000 yuan per month, with an annual salary of 1.08 million yuan. An ordinary county magistrate with eight grades earns 15 yuan a month, which is 4500 yuan, and an annual salary of 54000 yuan. Considering that a county magistrate in Song Dynasty only managed thousands of families, it's not bad. In Song Dynasty, besides salary, there were also salary, salary and salary,? Take a sip, There are various kinds of subsidies, such as kitchen materials, firewood and charcoal, additional payments, public money, coupons, and farmland. It's no wonder that the Song Dynasty is said to be unparalleled for its officials. No wonder Song Jiang sharpened his head to recruit an official. From the water margin on the specific case, the exchange rate is more reasonable. When Wu Yong persuades San Ruan to join the gang and rob shengshengshenggang, Wu Yong asks Ruan Xiaoqi to buy a jar of wine, 20 jin of raw and cooked beef and a pair of big chickens for one or two silver. It's about 300 yuan for one or two silver. In addition, on the tenth visit to the fengxueshan temple in Linchong, Lu Qian took out a silver or two and ordered three or four bottles of good wine and dishes at Li Xiaoer's shop. Similarly, the 44th time when Dai Zong Yang Lin invited Shi Xiu to dinner, Yang Lin also threw a silver or two for the restaurant to serve food and wine. Generally speaking, an ordinary small restaurant, 300 yuan for three people, is really free to order

10. In ancient costume plays, silver is used as a unit of money. How much is one or two silver? Take a look at the following derivation:

1 basic unit
there were many monetary units in ancient China, which were different from Dynasty to Dynasty, especially before Qin and Han Dynasties. Here we only discuss three basic units:
Yiwen coin (that is, a standard square hole copper coin)
one or two silver
one or two gold
although the above units are different in different dynasties, but at least there is little difference after the Tang and Song Dynasties, so we can get more stable and reliable data
exchange relationship
the exchange ratio of copper, silver and gold, just like the current foreign exchange price, often changes, unlike the one yuan equals 100 points. According to the following description:
"the price ratio of gold and silver rose from 1:8 around 1600 to 1:10 in the middle and late 20th century, and doubled to 1:20 by the end of the 18th century."
it can be seen that 1 liang of gold can be exchanged for 8-11 liang of silver. In the early years of Daoguang, one or two silver coins were exchanged for a crane, that is, one thousand Wen; By the time of the Opium War in the 20th year of Daoguang, one or two silver coins could be exchanged for 16700 RMB. Since Xianfeng, the price of silver has soared, and one or two silver coins can be exchanged for as much as two thousand two hundred and three hundred Wen. "
it can be seen that under normal circumstances, one liang of silver can be exchanged for 1000-1500 Wen of copper coins. In ancient times, one Guan coin or one Diao coin is 1000 Wen<

2 metal price
since the currency made of gold, silver and copper has value itself, and theoretically, the value of currency should be equal to the price of metal, we can answer the question of "how much is one or two silver" through the current price of metal
Kaiyuan Tongbao Tongqian of Tang Dynasty has a diameter of 8 points, 10 pieces weigh 1 liang, and Qianwen weighs 6 Jin and 4 liang; During the reign of emperor Shun of the Qing Dynasty, each copper coin weighed one and two cents and five percent, and then increased to one and four cents, which meant that each thousand Wen weighed eight Jin and twelve Liang. Although the ancient "two" weight units are different, they are about 40 grams, while the "Jin" is about 700 grams. The average weight of each coin is 5g< At present, the price of gold, silver and copper (RMB) is as follows:
Gold: 100 yuan / g
silver: 2 yuan / g
brass: 0.02 yuan / g
the calculation result is: 1 liang Gold: about 4000 yuan, 1 liang silver: about 80 yuan, 1 copper coin (1 coin): about 0.1 yuan

3 grain price

many Historical Monographs directly measure the price of goods through grain price Although it is not very accurate and objective to consider the grain price alone, it should be an extremely important reference. Xiaolin found the following record on the Internet: "the upper white rice (stone) is nine yuan and five Fen
