In a large bowl, mix together pork mince, chopped prawns, grated ginger, finely chopped shallots, light soy sauce, Shaoxing cooking wine, salt, and toasted sesame oil until well combined.
Place approximately 1 teaspoon of filling in the center of each wonton wrapper. Moisten the edges with water, fold diagonally or into desired shape, and seal tightly to prevent opening during cooking.
In a large pot, bring chicken broth to a simmer. Add garlic and ginger slices for extra flavor, then remove aromatics before serving.
If using bok choy or leafy greens, blanch them briefly in the simmering broth until tender.
Bring a separate pot of water to a rolling boil. Cook wontons in batches for 3-4 minutes until they float to the surface and are cooked through.
Using a slotted spoon, transfer cooked wontons to serving bowls. Ladle hot broth over wontons and add blanched vegetables if desired.
