This is my understanding of Spring Rolls versus Egg Rolls...
Spring Rolls are wrapped in softened rice paper and they are not usually cooked/fried. In my local Vietnamese Restaurants, they are usually served with a peanut sauce for dipping.
Egg Rolls (not Chinese but American Chinese) are always fried and are usually served with that nuclear pink sweet sauce in my local American Chinese Restaurants.
With Spring Rolls, because the rice paper is semi-transparent, there is almost an art to wrapping the ingredients in a pleasant "artful" manner (like the repetitive shrimp arranged in the photo).
