Heat a wok or large frying-pan over high heat and add the oil. Put in the preserved vegetables, garlic, and ginger and stir-fry for 1 minute. Add the rice wine, chili bean sauce, sesame paste, soy sauce, sugar, and stock. Reduce the heat and simmer for 3 minutes over low heat. Bring a large pot of water to boil and cook the noodles for 2 minutes if they are fresh and 5 minutes if dried. Drain well in a colander. Divide the noodles into individual bowls and ladle the sauce over them. Serve at once.
