Excuse me if a thread about this has already been made. I have searched and found none that specifically talk about the topic but always found this form of Kung Fu to be interesting. Even if it isn't the most efficient, though I still think it holds efficiency, it allows you to practice both flexibility and being unpredictable. So that's why this art fascinates me.
It's an interesting style in my opinion and it's very smooth while being unpredictably balanced.
