Preheat a large skillet or wok over medium-high heat. Add the sesame oil and ginger slices, and sauté until fragrant. Add the chicken pieces and stir-fry until both sides are lightly golden. Add the king oyster mushrooms and continue to stir-fry. Pour in the seasonings (rice wine, soy sauce, water, and brown sugar), and stir well so all the ingredients absorb the sauce.

Cover with a lid and simmer for about 10–15 minutes. Increase the heat to reduce the sauce until slightly thickened. Add the fresh basil and stir a few times until fragrant. Serve hot.
