This is shrimp. You can make soup, add some flavor when making salty rice, chop and stew egg soup, and make wonton stuffing. Dumpling stuffing is delicious, and adding a little shrimp when making noodles is also delicious. In short, you can put a little shrimp in the dish you need to cook. Before cooking, you can soak (or not soak) shrimp in water, or make soup to improve the taste.
