Those two angmos are amateurs at best and if there's a Japanese style belt grading, one would be white and the other yellow. Still a nong nong way from orange, green, blue, brown, black lorh.
Btw, the fake Kung Fu masters weren't defeated in under 5 minutes though you wouldn't be wrong, mathematically, to say they were defeated in less than 3 hours either.
In truth, they were taken down in less than 10 seconds! Lol!
If you pit Ip Man against Muay Thai boxers like Saenchai or Buakaw, your movie hero would enter the ring vertically and come out of it horizontally.
Bruce Lee learned Wing Chun and knew it couldn't take on other martial arts. It's full of theory like your Econs 101 but that's about it. Bruce took the techniques of other martial arts to develop his own jitkoondo.
BJJ fighters like the Gracies would destroy Ip Man in 9 seconds with a rear naked choke or arm bar.
To take a BJJ figter and defeat him, you need a judo master or a top wrestler.
Yi Long had an impressive record but he didn't train in Tai Chi or Wing Chun or he wouldn't have lasted.
You watched too many scripted Chinese kungfu films which invariably showed Tai Chi stances and movements for the optics and Wing Chun at close range for more optics because chewren loved to watch...
Yours Truly holds a black belt in Karate and trained in some judo and Muay Thai as well. Nao I do Tai Chi and have developed my own form which combines the Yang, Wu, Sun and Chen styles..... only for gentle exercise.
