Rinse the fish cakes with hot water, blot them with paper towel and slice them into desired size.
Heat oil in the skillet over medium heat and saute carrots and garlic to soften, about 2 minutes. Add onion and pepper and stir-fry for 2-3 minute. Add the fish cakes and continue to stir-fry until the vegetables are crisp tender. Add the oyster sauce and stir well. Add corn syrup if you desire glistening shine. Sprinkle sesame seeds over. Serve hot or at room temperature with rice.
