To make wontons: In large bowl, mix ground pork, shrimp, scallions, garlic, ginger, sesame oil, soy sauce, cornstarch, salt and pepper.
One wonton wrapper at a time, brush edges of two sides of wrapper with water. Add 1-2 teaspoons filling to center. Fold wrapper corner to corner so two wet edges meet two dry edges, creating triangle shape.
Press sides together to seal. Take two corners of triangle and join with water to create purse-like shape. Press to seal. Repeat with remaining wrappers and filling.
To make soup: In saucepan over high heat, stir broth, ginger, soy sauce, wine and sesame oil. Bring mixture to simmer.
Cover pot and turn down heat, simmering 10-12 minutes.
Add bok choy leaves, shrimp and scallions. Cook until shrimp are pink and heated through.
In separate saucepan, heat water to boil.
Drop in wontons in small batches and cook until floating, 5-7 minutes.
Transfer cooked wontons to bowls along with shrimp and bok choy from soup pot. Ladle broth, as desired, into bowls.
