Marinate shrimp in garlic oil. Chop cabbage, chestnuts, celery, very fine, including scallions all together. Fry shrimp. When pink, add vegetables. Mix well and cover. Cook for 2 minutes. Thicken with corn starch (mixture should be thickened). Let cool. Fill each egg roll wrapper as though they were ordinary won tons and fold like a large won ton. Deep fry three at a time or steam.
