Boil the noodles just until they are firm. Avoid overcooking, as they will soften further during stir-frying.
Once cooked, pour the noodles into a colander to remove all water.
Heat oil in a wok or skillet over medium heat. Gently scramble the egg until it’s mostly set, then remove it from the pan.
In the same pan, cook the garlic until it becomes aromatic.
Add cabbage to the pan and cook until it reaches your preferred level of tenderness.
Return the noodles to the pan. Add white sugar, golden mountain sauce, dark soy sauce, and oyster sauce. Stir thoroughly to ensure the noodles are well-coated with the sauce.
Add egg, carrots, and green onions to the wok. Stir everything together, then remove the pan from the heat. Serve immediately. Enjoy!
