Prepare Ingredients: Cut the ginger, green onion, and garlic. Clean the lobster and divide the body into 2-inch wide pieces. Dry the pieces with a paper towel.
Coat Lobster with Cornstarch: Lightly coat the meaty parts of the lobster pieces with cornstarch.
Make the Secret Sauce: Combine oyster sauce, soy sauce, sugar, salt, white pepper, and part of the cooking wine.
Fry the Lobster: Fry the lobster pieces until the shell turns bright red and the meat turns white. Drain the excess oil.
Stir-fry Aromatics: Add some oil back into the wok and stir-fry the ginger, garlic, and part of the green onions on high heat until fragrant.
Combine and Cook: Add the fried lobster back into the wok, stir-fry for 20 seconds, then add cooking wine, boiling water, and the prepared sauce. Bring everything to a boil with the lid on, then cook for another minute uncovered.
Thicken the Sauce: Add cornstarch slurry to thicken the sauce. Throw in the remaining green onions and drizzle sesame oil and some frying oil from before.
Serve: Plate the lobster on a bed of boiled Yee Mein noodles.
