Mix the sliced beef with soy sauce, cooking wine, and cornstarch and set aside. Heat the wok and 4 tablespoons of vegetable oil. Stir-fry the garlic and jalapeno pepper until fragrant, about 1 minute. Add the beef and the sauce ingredients and stir-fry over high heat just until the beef is no longer pink on the outside, about 2 to 3 minutes. Add the green onions during the last 1 minute of cooking.
