Cut both the sea intestine and the garlic chives into about 1-inch lengths and set aside. Slice the garlic into very thin slices and set aside. Heat a wok on a high setting for about two minutes. Swirl the vegetable oil into the wok and heat for another 30 seconds. Add the garlic slices and stir-fry for about 30 seconds until fragrant. Add the sea intestine and stir-fry for another 30 seconds. Add the Shaoxing cooking wine and continue to stir-fry until the wine is almost completely evaporated. Add the garlic chives, salt and ground white pepper to the wok and continue to stir-fry for about 30 seconds or until the garlic chives just begin to wilt. Plate and serve.
