Peel and trim 2 pieces of lotus root, then thinly slice them. Soak and prepare 8–10 pieces of black fungus (or wood ear mushrooms), and slice 1 red bell pepper into thin strips. Mince 3 cloves of garlic, slice 3 stalks of green onions, and thinly slice 1 piece of ginger.
Bring a large wok or pot of water to a boil. Add the lotus root, black fungus, and bell pepper, and blanch for 45 seconds. Drain thoroughly and set aside.
In a small bowl, combine 1/4 cup chicken stock, 2 tsp oyster sauce, 1/2 tsp salt, 1/4 tsp sugar, and 1/4 tsp white pepper. Stir well and set aside.
Heat 2 tbsp vegetable oil in the wok over medium heat. Add the sliced ginger and cook for 30 seconds to 1 minute until fragrant. Add the minced garlic and green onions, and cook for another 20 seconds.
Add the blanched lotus root, black fungus, and bell pepper to the wok. Stir-fry for 1 minute, then pour 1 tbsp Shaoxing wine around the perimeter of the wok.
Mix the stir fry sauce well then add it to the wok. Stir-fry for another 20–30 seconds, until the sauce thickens and coats the vegetables evenly.
