What the landlord wants to ask is the history of the evolution of China's ancient currency, right?

The following is the evolution of our currency:

The Evolution of Ancient Chinese Currency.

1) Pre-Qin: The people of the Shang Dynasty were good at doing business and used shellfish as currency; During the Warring States Period, iron coins appeared in various countries, and the Qin State used round square-hole coins, called half taels of coins (Qi used knife-shaped coins, Zhao used shovel-shaped coins, and Chu used ant-nose coins).

2) Qin and Han dynasties: Circular square-hole money was stipulated as the currency of the whole country. In the Han Dynasty, ** and copper coins were the main coins. The weight of copper coins in the Han Dynasty changed several times, and it was not until Emperor Wu minted the five-baht coins that it stabilized.

3) Three Kingdoms: At that time, the currency decreased, and cloth and grain became the main means of circulation. Cao Wei once abolished copper coins in the form of a decree and used them for physical transactions, which were not abolished in the future.

4) Sui and Tang Dynasties: still mint five baht coins, and prohibit the use of old coins of different sizes in the previous generation, which is conducive to the development of **. At the beginning of the Tang Dynasty, the currency system was reformed, and Tang Gaozu ordered to "abolish the five-baht money and open the Yuan Tongbao".

The newly minted "Kaiyuan Tongbao" became the common currency of the Tang Dynasty, and later issued a large amount. Subsequent generations of currencies have used it as a model. It was the earliest prototype of a bank in China, six or seven hundred years earlier than the financial institutions in Europe and the Mediterranean.

5) Song and Yuan Dynasties: During the Northern Song Dynasty, the world's earliest paper money "Jiaozi" appeared in Sichuan. The development from metal money to paper money is the inevitable result of social and economic development.

The promotion of paper money reduced the burden of merchants carrying metal money, which was conducive to the exchange of goods, reflecting the high development of commerce.

6) Ming and Qing dynasties: At the beginning of the Ming Dynasty, the main currency was paper money, and the auxiliary currency was copper money, and the use of gold and silver transactions was prohibited. By the middle and late Ming Dynasty, ** became the main currency in general circulation.
