At first, I watched Kathy Chow's performance. In fact, I have always thought that he is nearsighted from some characters such as hooligans and tycoons in Hong Kong dramas, and then his eyes are not very good when he looks at them, but sometimes the whole set he tells feels ok. I'm just saying that his mouth sometimes doesn't look so, er, beautiful after wearing it, but it's actually acceptable to look at it more.
