In the solemn fourth film about the real-life martial arts teacher, Ip Man takes on a racist bully in the US marine corps
Donnie Yen returns for his last coolly impassive outing as the real-life Chinese martial artist and wing chun master Ip Man, who trained generations of kung fu students, Bruce Lee being the most famous.
In this final, faintly solemn episode, Ip is a widower, growing old, and has been given a diagnosis of cancer. We see him leave Hong Kong and make a journey to the
United States in the 1960s (where his great student Lee is already making a name for himself) on a mission to find a private school for his tearaway young son. (In fact, the real Ip made no such journey.)
