Soak the glass noodles in room-temperature water for 20 minutes. Drain and cut into 3-inch pieces. Place in a resealable plastic bag to keep them moist and set aside.
Heat a large wok or skillet over high heat for 2 minutes. Reduce the heat to medium and add 3 tablespoons of Mazola Corn Oil. When the oil is hot, add the minced garlic and minced cilantro stem and stir for 1 minute. Add in the shiitake mushrooms and stir for 1 minute. Stir in the ground chicken and sauté for another 2 minutes, breaking it apart with a spatula. Add the julienned carrot and stir for 1 minute. Add the celery and bean sprouts and continue to cook, stirring for 1 more minute.
Season the mixture with the oyster sauce, light soy sauce, sugar, and black pepper. Stir to combine and cook for another couple minutes.
Sprinkle in the glass noodles and mix to combine, cooking for 1 minute. Transfer the filling to a large bowl or plate and let cool to room temperature.
In a small saucepan, combine the water and the tapioca starch or cornstarch. Stir to remove lumps. Over medium heat, bring the mixture to a boil, stirring often, until it starts to thicken but is still runny, 20 to 30 seconds. Transfer to a small bowl and let cool.
Separate the spring roll wrappers from each other. Stack them and cover with a damp kitchen towel to prevent them from drying out.
Lay a spring roll wrapper on a work surface with one of the corners pointing toward you. Place ⅓ cup of the filling horizontally about 1 inch below the middle line of the wrapper, leaving a 2-inch border at each side. Fold the bottom corner of the wrapper over the filling to the middle, using your other hand to hold on to the filling. Use both hands to roll the wrapper up once to the middle. Hold on to the rolled part with one hand and pull the right corner across about 1 inch toward the centre. Repeat with the left corner. Use both hands to make sure the filling is tight within the wrapper. Continue rolling a tight cylinder, leaving ½ inch of the top corner. Brush the corner with a little of the binding mixture, then continue rolling to close the spring roll. Repeat until all the spring rolls are made.
Heat the 4 cups of Mazola Corn Oil in a large wok or medium pot over high heat. Once the oil reaches a temperature of 375°F, reduce the heat to medium. Working in batches of 6 to avoid crowding the pan, use tongs or spider strainer to place the spring rolls, one at a time, into the oil. Deep-fry until golden brown, 6 to 7 minutes, gently moving the spring rolls through the hot oil with the tongs or spider strainer. Transfer to a large plate lined with paper towel. Repeat until all the spring rolls are cooked.
Let the spring rolls sit for at least 2 to 3 minutes before serving. Serve with the sweet chili sauce.
