To Yu-hang probably has his close resemblance to Donnie Yen to thank for winning the titular role in The Legend Is Born: Ip Man. After all, it was Yen's portrayal of the late Wing Chun master in Ip Man and its sequel that turned the character into a cinematic canon.At first glance, Hong Kong star To comes off as a younger, leaner Yen. But there is more to the 29-year-old than his comely physique. For one, he is the reigning World Kung Fu Champion.He is also an expert in numerous kung fu styles, including Wing Chun, which he studied for eight years. Moreover, he is the "grand-student" of Ip Chun, 86, Ip Man's real-life eldest son. To was also a flame bearer in the 2008 Olympics.
