Very few men are tall and handsome. Most handsome men are not really tall. I've met Pierce Brosnan once in San Francisco. He's really tall and handsome. Clint Eastwood is another example of course, but I didn't have the chance to meet him in person. For Chinese tall and handsome, I'd vote Chow Yuen Fatt and Simon Yam. I actually met Simon Yam at Centrepoint, Singapore. At that time, he has already started losing hair but he was still at peak suave in look and style.
If you talk about top pugilists being tall, that's even harder to find. Bruce Lee, Jacky Chan, Jet Li, even Sylvester Stallone, all not tall. I can only cite Chuck Norris. Height and size are actually impediments to martial arts and street fighting arts, not advantages. You're a bigger target to aim at and you can be tripped off balance more easily. Once tripped off balance, your 6ft or even 7ft becomes a 0ft mash on the ground at the mercy of your opponent even if he's just 5ft.
