Cut chicken into thin slices 2 inches long, cutting against the grain. Place in a bowl with dark soy sauce, rice wine, ginger, cornstarch, and 1 teaspoon sesame oil. Mix well and marinate for about 20 minutes.
Heat the oil in a wok or large skillet until very hot. Remove the chicken from the marinade using a slotted spoon and add to the pan.
Stir-fry the chicken for about 2 minutes until browned, then remove and leave to drain in a colander.
Pour off most of the oil from the pan, leaving about 2 teaspoons. Reheat the pan over high heat and add the dried chiles. Stir-fry for 10 seconds.
Return the chicken to the pan, add the remaining ingredients, and stir-fry for about 4 minutes, mixing well.
Serve the dish immediately.
Notes
This dish can easily be customized by adjusting the level of heat with more or fewer chiles.For a slightly sweeter taste, consider adding more sugar or using a sweet soy sauce.Serve with steamed rice or stir-fried vegetables for a complete meal.
