Heat oil in a large wok to 375°F. Gently loosen and separate the noodles. Fry half the noodles at a time (8 oz per batch), using tongs or chopsticks to spread into a circle. Fry for 7–10 minutes or until golden and crispy. Remove and drain on paper towels.
In a small bowl, whisk together broth, garlic, ginger, wine, soy sauce, oyster sauce, sesame oil, sugar, and cornstarch. Set aside.
In a clean wok, heat 1 tbsp oil over medium heat. Sear shrimp and scallops until just opaque, about 2–3 minutes. Remove and set aside. Add onion, carrots, celery, mushrooms, bok choy, baby corn, and broccoli. Stir-fry for 2–3 minutes.
Pour in the sauce and let simmer for 5 minutes until slightly thickened. Stir in the shrimp and scallops and cook for 1–2 more minutes. Remove from heat.
Place crispy noodles on a serving platter. Spoon the stir-fried mixture and sauce over the top just before serving so the noodles stay crispy.
