In a small bowl, whisk together the chicken broth, dark soy sauce, shaoxing wine, hoisin, soy sauce, maple syrup, ginger, and sesame oil to create the stir-fry glaze.
Preheat a large skillet or griddle over medium-high heat and lightly coat with a high-heat cooking spray.
Add the diced chicken and shrimp to the pan, seasoning with sea salt and black pepper, and sear until the chicken is golden and the shrimp are opaque.
Remove the proteins from the pan and set aside.
Add the broccoli, bell peppers, mushrooms, and snow peas to the hot pan, sautéing for 3-4 minutes until they are tender-crisp and vibrant.
Push the vegetables to one side of the pan, crack the egg onto the empty space, and scramble quickly until just set.
Return the chicken and shrimp to the pan along with the cooked white rice.
Pour the prepared sauce over the mixture and toss everything together for 1-2 minutes until the sauce has thickened and evenly coated the stir-fry.
