How to make salt in Vietnam by: Initially, on each salt field, the salt maker will treat the ground tightly to minimize the sea water infiltration into the soil. After that, continue to add sea water to dry to add solidity to the soil. When the salt field has met the requirements, people will begin to pump sea water inside. The initial field for people to use sea water is called "drying field", under the effect of sunlight, the amount of water in sea water evaporates less, at this time, the salinity in the water increases higher than the original. New people drain this water into the field below to create salt, this field is called "eating field". When the salt starts to precipitate, the people use the "flat rake" to rake the salt and gather it like small pyramids on each field. The same process repeats over and over again, reaping more and more salt. It is then carried ashore and sold to traders
