In a large mixing bowl, combine the ground beef with green onions, ginger, rice wine, soy sauce, sesame oil, white pepper, sugar, and salt. Stir thoroughly using a spatula or clean hands until the mixture becomes cohesive and well-seasoned. Add the shredded carrots, frozen corn, and peas, folding them into the meat mixture until everything is evenly incorporated. Cover the bowl with plastic wrap and refrigerate for at least one hour, allowing the flavors to meld together and intensify.
