Selected Zishifang clams are swan shells, named for their shape resembling swan eggs. The meat is firm and delicious, cooked in advance with minced garlic vermicelli, and frozen at a low temperature to preserve the deliciousness and nutrition of the ingredients. When eating, defrost it, put it on a plate, and steam it on high heat for 3 minutes. The barbecue is more delicious, appetizing and digesting, suitable for all ages.
