Add a little oil to stir-fry shrimps, and the flavor will be rich. Stir the minced onion and ginger into the pot to let the aroma enter the oil, especially the minced ginger. You can add more minced ginger to get a better effect of removing the fishy smell. The other method is to fry the shrimps first. When the shrimps turn pink, the fishy smell is slightly released, and then pour in the egg liquid. The eggs can suppress the fishy smell of the shrimps.
