You mention that " we train many styles including san shou" San Shou is not a style of fighting. The san shou you see today (Cung Le ) is not traditional san shou. That is kickboxing. San Shou techniques are in all style of kung fu. If you can use your techniques, blocks, etc in a fight or sparring situation, then THAT's san shou. Every san shou match you see today is kickboxing. You don't need to learn kung fu to do that. Just join a kickboxing school.
