During the Spring and Autumn Period and the Warring States Period, Beibi completely withdrew from the historical stage, and different currencies were formed in different regions due to social conditions and cultural differences. There are mainly: ant nose money in Chu area, cloth money in the Yellow River basin, knife money in Qiyan area and ring money in Sanjin and Shanxi provinces.
After the Qin dynasty destroyed the six countries, it abolished the old coins such as cloth coins and knife coins of various countries, and used square holes and half two coins as legal tender. Since then, the form of China's ancient currency has been fixed, and it has been used until the end of the Qing Dynasty.
Han inherited the Qin system and allowed the people to make their own castings. Copper coins in the Western Han Dynasty were still named by weight, but the weight gradually did not match the name. From the fourth year of Yuanshou (BC 1 19), Emperor Wu of the Han Dynasty ordered the casting of five baht coins in Shanglin Sanguan, and the right to coin was returned to the central government. There are three main types of copper coins in the Western Han Dynasty: half two, three and five baht.
At the end of the Western Han Dynasty, during Wang Mang's regency and the new dynasty's rule, he reformed Tuo Domineering and carried out four major monetary reforms in more than ten years. Wang Mang's monetary reform ended in failure. However, at that time, the technological level of coins reached an unprecedented height. The cast "Jin Cuodao" has been loved by collectors since ancient times because of its unique shape and exquisite technology.
All the money minted in the Eastern Han Dynasty was five baht.
During the period of social unrest in the Three Kingdoms, Wei, Jin, Southern and Northern Dynasties, the circulation scope of metal currency was reduced, and the shape and currency were different, which led to the phenomenon of valuing money over money.
During the Three Kingdoms period, Cao Wei implemented the monetary policy in kind, and Wei Mingdi resumed casting five baht, similar to the five baht in the Eastern Han Dynasty. Shu Han and Wu Dong practiced a lot of money. Shu coins mainly include: straight 150 baht, straight 100 baht, etc. Wu coins mainly include: Daquan 500, Daquan pawn money, Daquan 2000 and so on.
After the establishment of the Western Jin Dynasty, the old coins of the Han and Wei Dynasties were mainly used, as well as grain, silk and other physical objects. At the beginning of the Eastern Jin Dynasty, Wu's old money was still used. Later, a small coin with five baht appeared, which was said to be minted by Xing Wu Shen Chong, so it was also called "Five baht in Shen Lang".
During the Sixteen Kingdoms period, Li Shou, an adult Han Dynasty, produced the earliest annual money "Hanxing" in China. During the Southern and Northern Dynasties, the society was very turbulent, the currency value was chaotic, and the phenomenon of private casting was serious. From the Northern Wei Dynasty, Qian Wen gradually got rid of the restriction of discipline and gradually transitioned to the annual salary system.
