The significance of catching the sea
According to the law of the ebb and flow of tides, people living by the sea seize the opportunity of the ebb and flow of tides to salvage or collect seafood on the beaches and reefs along the coast, which is called catching the sea. Generally speaking, it is best to catch the sea during the flood season, because the sea recedes far and fast during the flood season, especially shellfish and seafood move slowly. When the sea recedes, these shellfish and seafood are placed on the beach or mudflat. This flood season is best on the second and sixteenth day of the second month of the lunar calendar every month.
