Gently rinse the dried lily flowers with tap water. Transfer to a big bowl and add 4 cups hot water. Rehydrate until tender, about 1 hour. Then remove tough ends of rehydrated lily flowers (*Footnote 3). Transfer 2 cups of the marinating water to another bowl without any of the solids that may have settled on the bottom. Set aside.
Gently rinse dried shiitake mushrooms with tap water. Add mushrooms and 2 cups hot water to a big bowl. Rehydrate until tender, about 1 hour. Then drain and slice the mushrooms.
Add wood ear mushrooms to a small bowl and add hot water to cover. Let rehydrate for 1 hour. When woodear mushrooms turn soft, gently rinse, drain, and set aside.
Combine shrimp, 1 tablespoon Shaoxing wine, 1/4 teaspoon salt, and 2 teaspoons cornstarch in a small bowl. Mix well by hand and marinate for 15 minutes.
Combine pork, 1 tablespoon Shaoxing wine, 1/2 teaspoon salt, and 2 teaspoons cornstarch in a small bowl. Mix well by hand and marinate for 15 minutes.
Chop and prepare the other vegetables. Combine the the 1/4 cup cornstarch with 1/2 cup water in a bowl. Mix well and set aside.
Heat oil in a 5.5-quart dutch oven over medium heat until hot. Add lily flowers, shiitake mushrooms, and wood ear mushrooms. Stir and cook for 1 minute.
Add green onion and ginger. Stir a few times until fragrant.
Add canned tomato, stir, and cook for 1 minute.
Add the 2 cups marinating water from the lily flowers, chicken stock, soy sauce, and salt. Bring to a boil over medium high heat, stirring constantly. Turn to medium low heat and simmer for 15 minutes.
Add the shrimp. Stir and cook until the shrimp turn white, 1 to 2 minutes.
Add the pork. Stir and cook until just cooked through, 1 to 2 minutes.
Whisk the cornstarch water again and swirl in half of it. Stir until fully incorporated. Slowly add the rest of the cornstarch water and stir, until the gravy reaches the desired thickness (you will have some slurry left if you prefer a thinner gravy). Taste the sauce and add more salt if needed. Drizzle with sesame oil or homemade chili oil to finish up, if using. The sauce should be slightly salty by itself. Remove the pot from your stove and cover to keep hot.
Cook noodles according to instructions. Drain and transfer to each serving plate.
Serve the sauce hot over the noodles. Enjoy!
