In a bowl, combine chicken slices with water, Shaoxing rice wine, salt, baking soda, cornstarch, and oil. Mix well and let marinate for 10 minutes.
In a separate bowl, whisk together water, soy sauce, sugar, chicken bouillon, dark soy sauce, cornstarch, and toasted sesame oil to prepare the stir fry sauce.
Heat a large wok or skillet over medium-high heat and add a small amount of oil.
Add the marinated chicken to the pan and stir-fry until the chicken is cooked through and lightly browned, about 4-5 minutes.
Add your choice of mixed vegetables (such as bell peppers, broccoli, carrots, and snap peas) to the pan and stir-fry for 3-4 minutes until tender-crisp.
Pour the stir fry sauce over the chicken and vegetables, stirring constantly until the sauce thickens and coats everything evenly.
Remove from heat and serve immediately with egg fried rice or shrimp lo mein to complete your meal.
