Can we live without salt ? Salt is very important to us . We need salt in our food . Animals need it , too. Most of the salt in our country comes from the sea. People dig very big pools(池塘) and let sea water in . When the sun dries(弄干) up the water , people can get salt from the ground . The salt is white, clean and beautiful .

There are a lot of salt wells(井) in Sichuan . A salt well is much like a water well . People bring the well water up to the ground and then dry it in big jars(坛子) over fire .
