1. After buying live oysters, you can soak them in salt water overnight. Put a small amount of salt grains in the water, put the live oysters in it, and then move them to a cool place, or clean the live oysters and pack them. Place in a basin, cover with a damp cloth and store in the refrigerator.

2. If you need to store the oysters for a long time, you need to separate the oysters into fresh-keeping bags and then store them in the freezer.
