Does anyone know how to make Chinese Chicken Wings?

??? Christmas day I went to my uncle's house for nosh dinner.. just us and his girlfriend whom I've known for 30years. we just grazed all afternoon. Only had two hot things, pigs in blankets and teriyaki chicken wings which we made there. While having the dips earlier in the day we put two deep sided plates out and spread out the chicken wings in there and then bathed them in teriyaki sauce. Let them sit for an hour or so, turning them every once in a while. Then we put them into the toaster oven and threw some sauce over them and baked them until for (TBH IDK but it was about 15 minutes. Took them out and checked them. They were fine so we took them out and did the same with the other plate.
