Start by preparing the stir-fry sauce mixture. Combine the wine, light soy sauce, sugar, white pepper, and sesame oil. Set aside.
(At this point, if using pork or chicken, you’d preheat the wok until it was smoking, add a tablespoon of oil, and then sear the meat until just cooked. Remove to a bowl and set aside. If not, move on to the next step.)
Place a wok over medium heat. When the wok has heated, add the oil and the ginger. Cook for 30 seconds, and add the garlic. Cook for another 30 seconds.
Add the tofu, and stir-fry for another minute. Turn up the heat to high, add the garlic chives, and stir-fry for 1 minute (at this point, you can also add your pre-cooked meat, if using). Add the sauce mixture, and stir-fry for another 30 seconds. Season with salt to taste. The dish is done once the chives are wilted. Serve immediately.
