In a bowl, add all your chicken mixture ingredients. Toss ground chicken, garlic, ginger, scallions, soy sauce, sesame oil, Shaxiong wine, sugar, oil, water and pinch of sugar. Mix well until combined.
Set aside in the fridge for 30 minutes to allow all the flavors to combine. In the meantime, prep your sauce. In a bowl, mix chili oil, vinegar, soy sauce, sesame oil and sugar. Set aside.
Take your chicken mixture and wonton wrappers and get ready to assemble. Place a small bowl of warm water next to you. Lay your wonton wrapper flat. Put your finger in the water and spread your wet finger on all sides of the wonton wrapper.
Add in a little bit of the chicken mixture (about a teaspoon) and fold the wontons over to make a triangle. Seal shut with your fingers. Fold the triangles left and right corner towards each other, with one of the corners overlapping and seal shut with a dash of water on your finger again until sealed. Place on a tray and repeat.
Heat a pot with water until boiling. Add in your wontons and steam until your chicken is cooked on the side, you will know when it floats to the top and the wrappers become translucent. Go in phases so they don't stick to each other.
Use a slotted spoon and bring all your finished wontons in a bowl, it's okay to bring excess wonton water in the bowl, you want that.
Toss in your sauce, and about 2-3 tablespoons of the wonton water. Mix really well until all combined. Serve and top with sesame seeds and green onions!
