In a medium bowl, cover the shiitake mushrooms and wood ear mushrooms with boiling water and soak until they are soft, about 15 minutes. In a small bowl, cover the dried shrimp with room temperature water, and soak until tender, about 5 minutes.
While the dried ingredients are soaking, bring a large pot of water to a rolling boil over high heat, and blanch the dried rice noodles until al dente, about 1 minute. Drain in a colander and set aside.
Drain the dried shrimp through a fine-mesh sieve. Drain the shiitake and wood ear mushrooms. Trim the shiitake stems and discard. Thinly slice the shiitake mushroom caps and wood ear mushrooms and set them aside separately.
Heat the oil in a wok over medium heal. When it is hot and shimmering, add the sliced shiitake mushrooms and the dried shrimp, and cook until they smell lovely, about 40 seconds. Increase the heat to high, toss in the cabbage, carrots and wood ear mushrooms, and stir-fry until the cabbage is wilted and soft, about 1 minute.
Use your spatula to gently push the vegetables and aromatics to the sides of the wok, leaving space in the middle. Pour the sauce into the center of the wok, then immediately add the rice noodles and pork on top. Toss and stir everything together until the liquid is completely absorbed and the pork is cooked through, 1–2 minutes. Turn off the heat and transfer everything to a clean serving platter. Enjoy while hot.
