1. Blend your cooking sauce: In a small bowl, mix together fish sauce, soy sauce, sugar, and rice wine.
2. Have your other ingredients lined up next to the stove: oil, garlic, bean sprouts, and Chinese chives.
3. Heat a large--12 inches or wider--heavy skillet or wok over high heat. Swirl in oil. Toss in garlic and fry, stirring constantly, for 15 seconds until it just begins to brown. Add bean sprouts and then cooking sauce, and fry, stirring and tossing, for about 90 seconds. Sprinkle in chives and cook, tossing well, for 30 to 60 seconds.
4. Remove pan from heat and stir in a couple of pinches of pepper, and salt to taste. Lift the sprouts out of the hot pan and onto a platter quickly, so they don't continue cooking.
