There are also kind of Salted fish common in South China, or Hong Kong, which is sun-dried for weeks or month after salting them. Large fish would be used and would cook before serving/ eating, and is usually used to boost the taste of another dish, and seldom just eat it alone cause it is too salty. While these Salted fish could be self made, and cook it after salted. 
Different from dried anchovies, which should be cooked and dried as a snacks
