Dry chow fun uses the technique of dried frying (gon chow). This technique uses a very hot wok with a little oil and frying the food quickly with minimal oil, hence the name dry fry (gon chow). Dry chow fun is cooked with this method, using just soy sauce so the noodles come out flavorful and dry (not saucy). Wet chow fun on the other hand is chow fun that is stir-fried as well but is either cooked with gravy (sauce) or a sauce is poured on top. It's a wet chow fun dish with a lot of sauce.
