In a small bowl, whisk together the soy sauce, sugar, vinegar, wine, and sesame oil; set aside.
Heat 1 Tbsp. peanut oil in a large pan over medium heat. Add eggplant and stir fry until the edges are golden brown and center is tender.
Transfer eggplant to a plate and add remaining peanut oil to pan. Add garlic, ginger, and chiles; cook until aromatic.
Return eggplant to pan along with scallions, tossing to incorporate. Pour in sauce and stir fry until vegetables are coated.
Made a double batch in two batches. Omitted green onion; used 1/4 tsp. red chile flakes instead of red chiles; used grated galangal instead of ginger; used regular rice wine vinegar. This turned out very well. The eggplant is very creamy and delicious served with rice.
Made a double batch with ~650g eggplant, 60g garlic, and 20g galangal instead of ginger. Added about 1 Tbsp. minced green onion root left over from a separate recipe, a pinch of red pepper flakes instead of red chiles, and rice wine vinegar instead of Zhenjian vinegar.
