In a bowl, combine the sliced chicken with water, Shaoxing wine, salt, and baking soda. Mix until the chicken absorbs most of the liquid.
Add 2 tablespoons cornstarch and mix until the chicken is well coated. Drizzle in 1 tablespoon oil and mix. Let marinate for 10 to 15 minutes.
In a separate bowl, whisk together soy sauce, water, sugar, 1 tablespoon cornstarch, sesame oil, and bouillon powder if using. Set aside.
Bring a pot of water to a boil. Blanch the vegetables starting with the heartier ones like broccoli and carrots for 2 to 3 minutes, then add tender vegetables like snap peas for 30 seconds. Drain and set aside.
Heat a wok or large skillet over medium-high heat with enough oil to coat the bottom. Add the marinated chicken in a single layer and cook for 2 minutes per side until just cooked through. Remove and set aside.
Keep 2 tablespoons oil in the pan and reduce heat to medium. Add garlic and ginger, stirring constantly for 20 seconds until fragrant.
Give the sauce a quick stir and pour into the pan. Stir constantly as it heats and thickens, about 1 minute, until glossy.
Reduce heat to low. Add the chicken back and toss to coat. Add the blanched vegetables and mix until everything is coated in sauce.
Serve immediately over rice and enjoy.
