In a bowl, combine the soy sauce, hoisin sauce, oyster sauce, honey, brown sugar, and rice vinegar to create a marinade.
Add the chicken thighs to the marinade, ensuring they are well coated. Let them marinate for at least 30 minutes.
Preheat your grill or skillet over medium heat.
Cook the marinated chicken thighs for about 6-7 minutes on each side, or until they are fully cooked and have a nice glaze.
Remove the chicken from the heat and let it rest for a few minutes before serving.
