Can we live without salt? No. 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 great pools and let the sea water in. When the sun dries up the water, people can get salt from the ground.
The salt is white, clean and beautiful. There are a lot of salt wells 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 pans over fire. In this way they get salt.
We can also get salt from salt mines. Some years ago, people in Jiangxi found a big salt mine and soon opened it. People there need no salt from other places now.
In the north of our country, there are many salt lakes. Some of these lakes are very big and can even meet the needs of our people for many years.
