in the movies, TV dramas and operas reflecting the current situation of ancient Chinese society, people can often see the gold and silver ingots as the symbol of wealth. Those dazzling, round shaped gold and silver ingots are fascinating and therefore familiar to modern people. As the ancient Chinese currency, gold and silver Yuan Bao are the highest value currency after all, highlighting the wealth and value of the owner< In fact, gold and silver ingots, as ancient Chinese currency, were cast in the Han Dynasty, but they were not widely circulated. It was called "silver cake" and "silver wat" before Sui and Tang Dynasties, and "silver ingot" ring song and Jin Dynasties. However, the circulation of silver ingots as a means of payment began in the Jin Dynasty. In the Jin Dynasty, each ingot of silver weighed fifty Liang, which was worth a hundred Guan. In December 1197 (the second year of Cheng'an), the name of "Cheng'an baohuo" was changed to one or two to ten Liang, which was divided into five grades, and the amount of money was reced by two times every two years. So far, silver has become legal tender, which is used together with money and banknotes, and plays a more and more important role in social economy. This trend affected the Yuan Dynasty, and finally changed the copper standard to silver standard. Since the Yuan Dynasty, silver was adopted as the value standard, resulting in a major reform of China's currency system. Therefore, the silver ingots of Yuan Dynasty are generally called "Yuanbao". At this time, the word "Yuanbao" contains the meaning of "treasure of the Yuan Dynasty", which is the main origin of the name of Yuanbao. But it does not refer to the shape, but refers to the ingot as Yuanbao< However, it was not the legal tender of the country. Until the Qing Dynasty, silver ingot was the main currency circulation. Because of the different weight, it was also called "silver ingot". In the Qing Dynasty, the shape of silver ingot changed to a horseshoe shaped ingot, so it is also called Baoyin. After melting and casting, the ingots can be divided into big ingots, medium ingots and small ingots, but they are generally called silver ingots or silver ingots. In addition, broken silver still exists. As all regions can cast precious silver by themselves, the types and names of precious silver are generally the same in the whole country, but the quality and weight are not the same. Different grades of silver are used in different regions, and there is a certain conversion rate between them. After the Opium War, the influx of foreign silver (silver dollar) and the popularity of self cast silver dollar did not fundamentally change or replace the status of silver system. It was not until 1933 that silver was no longer used as currency.
