Bring a pot of water to a boil and cook the shrimp until about 80% done. Remove and set aside.
Heat oil in a wok over high heat. Add the ginger and garlic slices and stir-fry until fragrant. Add 1 pack of Lee Kum Kee Sichuan Style Spicy Stir-fry Sauce Mala Flavour and stir-fry until aromatic. Add the shrimp and vegetables (lotus root, potato, and black fungus), and stir-fry well to coat evenly with the sauce.
Finally, add the onion, green bell pepper, and red bell pepper. Reduce to low heat and stir-fry until the vegetables are cooked through and have absorbed the flavors.
