Most of the salt in our country comes from the sea(大海). People dig(挖) great pools and let sea water in. When the sun dries up (晒干) 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 over fire. In this way, they get salt.
We can also get salt mines(矿). Some years ago people in Jiangxi found(发现) a big salt mine and soon opened it. People there no longer (不再) need salt from other places(地方).
In the northwest(西北) of our country, there are many salt lakes(盐湖). Some of these lakes are very big. The salt in a big lake even can meet the needs of our people for many years.
