Mix the sliced chicken with water, soy sauce, cornstarch, baking soda, and vegetable oil in a medium bowl.
Let it marinate for 15-20 minutes to infuse flavors and tenderize the meat.
Combine hoisin sauce, oyster sauce, soy sauces, dark soy sauce, cornstarch, sugar, garlic, and chicken broth in a small bowl.
Stir well and set this noodle sauce aside for later.
In a large pan filled with boiling water, blanch the fresh noodles for 30 seconds.
Strain them and set aside to prevent overcooking.
Heat vegetable oil in a large pan over medium heat.
Fry the marinated chicken for 4-5 minutes until fully cooked, then remove it from the pan.
In the same pan, quickly sauté the carrots, bell pepper, and cabbage for about 60 seconds until they are slightly tender.
Add the noodles to the pan with the vegetables, then pour in the noodle sauce.
Toss everything until the noodles are well coated with the sauce.
