Can you imagine a life without salt? No, salt is very important to us, and we need salt in our food every day. Without enough salt in the food, you will get ill. Animals need salt, too. They need salt to grow strong and faster.
Most of the salt in our country comes from the sea. People dig very big pools and let seawater in. When the sundries 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 Province of China. 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 over fire. In this way, they get salt.
We can also get salt from salt mines. A salt mine may be found under the ground. Some years ago, people inJiangxi Province found a big salt mine and soon opened it. People there don't need salt from other places anymore.
In the northwest of our country, there are a great number of salt lakes. Some of these lakes are very big. The saltin a big lake will be enough for all the people in our country for as long as hundreds of years.
