The gold here is not real gold, but a mixture of gold and brass. You know, gold is very valuable. If the monarch really gave two thousand gold at that time, even the monarch of a country could not afford such a loss. In addition, the smelting technology at that time was not mature enough, so the gold people referred to was actually brass. There is often a saying in TV dramas that the gold prize is given to two thousand. In fact, this is also the routine of ancient monarchs. The ancient people's understanding of these gold is completely different from that of modern people. Therefore, the concept of the term "golden twelve thousand" has also changed. During the Warring States period, gold did not necessarily represent gold, because the mining and smelting technology in the Qin Dynasty was not developed, and there was not much gold in the country. So people also called brass gold at that time. If it was the Warring States period or the Qin Dynasty, if the monarch gave 22,000 gold, it would probably be 22,000 brass.

It was not until the Han Dynasty that people began to mature their own alchemy techniques. Even though people's technology was perfect at that time, the number of gold mines was relatively small, which could not meet people's demand for gold at that time. Since gold has been a rare thing since ancient times, people used it as an ornamental and made cakes at that time. The weight of these cakes is also certain, and each piece of gold is one catty. If the monarch had really rewarded the minister with two thousand gold, it would have caused great losses to the monarch. The monarch usually gives a mixture of gold and brass. Because the surface color of this mixture is exactly the same as that of gold, there is not much difference in the eyes of those ministers. Later, people's commodity transactions became faster and faster, and gold gradually became the representative of wealth. Although many gold owners promised to give two thousand dollars, they actually used silver, and some monarchs even replaced their original promises with copper coins.
