I have no idea how either of these teams play but I do now know they love to fight. It's a bench clearing brawl between Team China and Team Japan. I don't know the age of the teams but they appear to be wearing mask so I can assume maybe Juniors? It's not the best fight I have ever seen but there is a few parts where dudes just come up from behind and pretty much stage dive on a pile of people fighting.
