It's a tie. For a W in the sheet, they need to make a parade in the forbidden city.
A side note, Vietnamese are known for their unity and camaraderie. Had an experience a few years ago, where practically all Vietnamese in my school knew my name/looks/data due to me living in a room full of Vietnamese students and me kicking a Vietnamese player in a friendly football match.
Everywhere I go, I feel the tension and glaring looks from them.
Moral of the story, stay out from them, ask Rambo if you don't believe me. They maybe small, but they're though.
