I forgot to mention an excellent movie we just watched: The Ip Man. it starts out in 1935 just before the Chinese invade Japan and is about A Wing Chung master who was very careful about using his martial arts. He was the best there was and once the Chinese came in he was eventually forced into a tournament by one of their generals who wanted to fight the best as he felt Japanese kung fu was superior to Chinese martial arts. It's based on a true story. Ip Man became Bruce Lee's teacher.
