Combine the pork, shrimp, wine, ginger, minced green onion, soy sauce and sugar in a big bowl and mix well.
Let this mixture stand for half an hour so the flavors can blend.
Put a teaspoon of this filling in the middle of each wonton wrapper.
Wet the edge of each one with water and pull the top corner over to the bottom, folding the wonton wrapper to enclose the filling in a triangle shape.
Press the edges firmly to seal.
Bring the left and right corners together over the filling and overlap the tips. Moisten them with water and press them together.
Bring the chicken stock to a boil and drop the wontons in. Let them simmer for 4 minutes or until they turn translucent and float to the top.
Garnish the soup with sliced green onion and cilantro before serving.
