In ancient China, there were often wars, sometimes internal wars, and sometimes foreign invasions, in order to defend the country, most dynasties attached great importance to the army, at that time, basically the use of cold weapons, sometimes, the victory or defeat of a war determines the fate of such a country.
In fact, other countries in ancient times were the same, every conquest was accompanied by the death of many people, but soldiers to go to the battlefield must also be paid, sometimes there is a thing that can even replace currency, especially in the Roman Empire soldiers, this kind of thing has become hard currency.
This is salt, some of the salaries of Roman soldiers are salt, called "salary money" by soldiers, ancient times and we are not the same, salt is very important for everyone, There are many types of salt in China, but it is not allowed to sell illegal salt, and the government's control of salt is very strong.
Anyone who is caught selling smuggled salt is basically going to be executed, but why do people continue to cross this line? Because the profit of selling salt in ancient times was too great, you can quickly make a fortune, you can look at those salt merchants, and those officials who squeeze their heads and want to take charge of this piece, you know that this is definitely a profiteering industry.
In the final analysis, in fact, in ancient times, the technology is relatively backward, no matter what way to extract salt, it is very troublesome, but not to eat salt is absolutely impossible, when people do not eat salt for a long time, it will produce a lot of symptoms, harmful to the human body without any benefit, this kind of condiment for us is very common, a country has a very important role, salt in ancient times are sold by the state, prohibit the sale of private salt, if it is a small crime will not get to the point of killing the head.
It is said that in the Battle of Yanhuang, it was because of the outbreak of salt, which seems to us to be a very incredible thing, a war is only because of such a small condiment, from which it can be seen how important salt was in ancient times, if people do not eat salt, they will because the sodium content is too low, resulting in no appetite, fatigue, and even vomiting and other symptoms, after going to the battlefield, such an army naturally has no combat effectiveness to speak of.
So in the Roman Empire, those soldiers, the salary contains salt, not only for seasoning, but also to maintain the meaning of combat effectiveness, sometimes, Roman soldiers will even use these salts as currency, absolutely hard currency, but with the development of the times, the extraction of salt has been very simple, there will be no longer the previous situation, we only need to be very cheap to buy edible salt, make the delicious food we want to eat.
