Put the chicken in a large bowl. Add the lemongrass, tamari, oyster sauce, seasoning sauce, soy sauce, sugar, pepper, turmeric, lime leaves and cilantro roots to a blender and blend until combined. Pour the marinade over the chicken, making sure that the chicken is fully submerged. Let marinate in the refrigerator overnight.
Preheat a grill to 425 degrees F.
Remove the chicken from the marinade and grill for 5 minutes on each side, or until cooked through.
