If using fresh noodles, blanch them in boiling water for about 1-2 minutes, or until they are cooked through but still have a nice chew. Drain and rinse with cold water to prevent sticking. Set aside. If using dried noodles, cook them according to package directions.
Heat the vegetable oil in a wok or large skillet over medium-high heat. Add the ground meat and cook, breaking it up with a spoon, until it's browned and cooked through.
Add the minced garlic and ginger to the skillet and cook for about 30 seconds, or until fragrant, stirring constantly.
In a small bowl, whisk together the sweet bean sauce, yellow soybean paste, soy sauce, sugar, and water.
Pour the sauce into the skillet with the meat. Bring the mixture to a simmer, stirring occasionally. Reduce the heat to low and let it simmer for about 10-15 minutes, or until the sauce has thickened slightly. This allows the flavors to meld together beautifully.
Divide the cooked noodles among serving bowls. Spoon a generous amount of the meat sauce over the noodles.
Top with the shredded cucumber, bean sprouts, carrots, and sliced scallions.
Give everything a good mix before eating, ensuring the noodles are well coated with the delicious sauce.
