Prepare the Broccoli: Soak the broccoli in salted water headside down, then trim by cutting at the stems without cutting into the buds.
Prepare Garlic and Ginger: Smash, peel, and mince a few cloves of garlic and an equivalent amount of ginger.
Make the Stir-Fry Sauce: Combine salt, sugar, cooking wine, chicken bouillon powder, corn starch, water, and oyster sauce.
Blanch the Broccoli: Add salt and oil to boiling water, then blanch the broccoli. After it boils again, remove the broccoli and shock it in ice water.
Stir-Fry: In a hot wok, add oil, then garlic and ginger, stir-frying until fragrant. Add the broccoli, a splash of cooking wine, and the prepared sauce, stirring well. Finish with a bit of oil for a glossy shine.
Serve: Plate the stir-fried broccoli and serve.
