Great Wall of China and salt

Great Wall of China and salt
The tiny salt crystals that you sprinkle on your scrambled eggs play a vital role in bringing the Great Wall of China into existence. During ancient times, salt was an extremely valuable commodity. Apart from being used as an essential food preserving agent, salt also served as a form of money. 

Roman soldiers were paid in salt, hence the term "salary". Realizing how dependant the people were in the mineral. China decided to introduce salt taxation, implemented under the Qin Dynasty. The law fixed the price of salt at a higher level. Doing so allowed the governments to purchase salt at a lower price than sold to the people for profit. The revenue earned was used to fund the army as well as to finance the early developments of the Great Wall. 

Here is some interesting fact about salt that we should know :

1. The amazing Salar de Uyuni or Salar de Tunupa (the world’s largest salt flat at (10,582 square kilometers or 4,086 sq mi.) in southwest Bolivia becomes a mirror like when a thin layer of water lies on top. It also contains half of the world’s supply of lithium.

2.  Taking too much salt can be deadly, you need to take about 1 gram of salt per kilogram of weight to die and this was used as a method of ritual suicide in China.

3. Roman soldiers were paid in salt (hence the word Salary), but in fact they were paid in normal money. The connection with salt is possibly maybe through the fact that the soldiers protected the salt roads leading to Rome.
