Maybe i didnt ask the question right, so ill try to re-ask with a different question: How would one fight with Xing Yi Regarding Steps/Techniques/vs other styles (as mentioned before, the bouncing type of person vs xing yi, say if you cant catch up with him)/speed/power.

Yes, i do not know anything, but this is why i ask. Also, I believe that Wing Chun should have the same pummeling thing as in xing yi, or maybe no
