Season the ground pork with ¼ tablespoon of sugar, ½ tablespoon of soy sauce and ½ tablespoon of cooking wine, set aside.
Whisk 1 tablespoon of potato starch and ¼ cup of water in a container and set aside.
Heat 2 tablespoons of oil in a pan, stir fry the pork over medium heat for about 3 minutes until no longer pink, remove from the pan.
Pour in another 2 tablespoons of oil, throw in the cabbage, carrot and bean sprouts and stir fry for about 4-5 minutes until soft.
Add the pork back into the pan, toss in ¼ teaspoon of salt and pour the potato starch mixture around the pan, continue cooking for another 2-3 minutes. (This is the filling for the egg rolls)
Make egg rolls (I made about 12 of them with the fillings).
Heat about 4 cups oil in a deep pan over high heat until the oil is hot enough for frying, carefully add the egg rolls into the oil, fry for about 1 minute each side until crispy and golden brown.
Place the egg rolls on paper towel to drain the excessive oil.
Serve with lettuce and dipping sauce of your choice.
