We have no idea about men first began to use salt. But we do know that it had been used in many different ways the history. For example, in many history books it is that people who lived three thousand years ago ate salted fish. Thousands of years ago in Egypt, salt keep the dead. It can keep the dead bodies decay（腐烂）. In the eighteenth century, a person who stole salt was thought to broken the law. If a person was caught stealing salt, he would be thrown into prison. Books also record that in England about ten thousand people were put into prison during that century stealing salt! In the year 1553, if a man took than his share of salt, he would be thought to have broken the law and would be punished(惩罚). Salt was very important on the dinner table of a king. It was always put the king when he sat down to eat. Then important visitors sat near the salt less important visitors were given seats farther away from it.
