What do evil gold and gold mean respectively?

American dollars and evil gold refer to bronze respectively, and evil gold really used for farming refers to iron. Evil gold, a Chinese word, is pronounced as ι j ι n, and its definition was called iron in ancient times. Dollar refers to good quality metal. In the pre-Qin period, it generally referred to bronze. "Strange Language of Mandarin": "The dollar casts a sword and halberd, trying dogs and horses; Evil gold is used to cast a catty and try loam. " And show the development level of iron smelting and iron products in the Spring and Autumn Period. However, archaeological discoveries and studies show that weapons in the Spring and Autumn Period were not only made of bronze, but also made of iron. Iron is used to make farm tools, and bronze is also used to cast farm tools. At that time, there was no understanding and distinction between beauty and evil about bronze and iron.

Words such as "dollar" and "evil gold" come from pre-Qin ancient books such as Guoyu. Many historians believe that the "dollar" used for casting weapons refers to bronze, and the "evil gold" used for farming refers to iron, thus demonstrating the development level of iron smelting industry in the Spring and Autumn Period.

However, archaeological discoveries and studies show that in the Spring and Autumn Period, weapons were not only made of bronze, but also made of iron. Iron is used to make farm tools, and bronze is also used to cast farm tools. During the Spring and Autumn Period, a large number of ironware were articles for aristocrats or found in aristocratic tombs. At that time, there was no understanding and distinction between beauty and evil about bronze and iron. In view of the fact that artificial iron smelting was still in the primary stage of development at that time, and bronze was still the main metal used in social life, it can be considered that "USD" and "evil gold" both refer to bronze, "USD" is high-quality bronze, and "evil gold" is inferior crude copper. It means that iron can't catch up with bronze without exercise. Later, with the development of iron smelting technology, the hardness of iron surpassed that of bronze, and its application became more and more extensive.

There are three main reasons for interpreting "dollar" as bronze and "evil gold" as iron: first, in the pre-Qin period, advanced weapons such as swords and halberds were made of bronze instead of iron; Second, bronze is expensive and beautiful, and it was not used to cast farm tools in ancient times; Third, iron that has not been refined into steel is not as easy to oxidize as bronze, so it is divided into beauty and evil. If the historical facts are true, it makes sense to interpret "dollar" and "evil gold" as bronze and iron respectively. However, the historical picture reflected by a large number of archaeological discoveries is far from the above understanding, or even the opposite, which urges us to reflect on the explanations of our predecessors.
