In a small bowl, mix the sauce: doubanjiang, oil, ground chilies, Sichuan pepper, dark soy sauce, soy sauce and sesame oil. In a separate bowl, marinate the chicken or beef in Shaoxing wine.
Heat wok until very very hot, then lower heat and add 2 tablespoons of the caiziyou and swirl around the wok. Add chicken or beef and let sear, undisturbed, on one side. When lightly browned, continue stir-frying until just cooked through. Remove and reserve.
Clean wok if needed, return to heat, and add the remaining 2 tablespoons caiziyou. Add vegetables and stir-fry over high heat until they start to brown but are still crispish. Add garlic slices and cook briefly, then lower heat, push the veg to the sides of the wok and add the stir-fry sauce into the center. Cook it briefly, then add back the chicken, or the beef and cilantro, and mix all ingredients well. If too dry, add water to reach your desired amount of sauce.
