Hello all Southern Kung Fu practitioners!

I am only 15 and so am very ignorant of many things...

I study Northern Mantis, but have studied a small amount of Lau Gar and was wondering a few things...

a) How do southern kung fu people train on a regular basis? and what are the basics of your styles?

b) Have there ever been any famous historical fights between a northern and a southern kung fu fighter?

Many thanks!

S
