For the filling: Heat a wok over high heat. Add the oil, give it a swirl, and then add the ginger and garlic and toss for a few seconds. Then add the chicken strips and stir-fry for 2 to 3 minutes. Add the Chinese five-spice powder and toss well. Stir in the shrimp and cook for 1 minute, and then pour in the Shaosing rice wine and cook until absorbed. Stir in the soy sauce, slurry and sriracha and toss well. Transfer to a plate to cool.
For the egg crepe: Crack one of the eggs into a bowl and lightly beat with a fork or chopstick. Sprinkle in the salt and pepper. Heat a small pan or wok over medium heat and add 1 tablespoon of the oil. Add the beaten egg mixture and swirl around to make a thin egg "crepe". Gently cook for 1 minute, then flip and cook until lightly browned. Remove from the wok and set aside. Repeat with the remaining egg and oil.
For the vegetables: Mix together the mushrooms, onions, beansprouts, carrots and red peppers in a large bowl. Reheat a wok and add some peanut oil. Add the vegetables and oyster sauce, toss well, and cook for less than 1 minute. Remove, drain and set aside.
For frying and assembly: Heat the oil in a deep pot or wok over medium-high heat until hot. Lay 2 pieces of the spring roll wrapper out onto a flat surface in a diamond shape. Place one egg crepe right in the middle. Spoon 2 tablespoons of the filling into the center and top with the stir-fried vegetables. Brush over the wrapper edges with the beaten egg using a pastry brush; this helps stop the spring rolls from bursting open while frying. Fold each of the opposite corners in over the filling and roll the wrapper into a cigar shape. Repeat with the remaining wrappers and fillings.
Deep-fry the spring rolls until golden brown, 3 to 5 minutes. Drain on paper towels, garnish with scallion curls and serve with sweet chili sauce.
