In one Hong Kong tournament, a CLF guy threw a right hook punch at a WC guy. The WC guy used left Tan Shou to block it. The right hook knocked down the left Tan Shou and still hit on the WC guy's head. The WC student went back and asked Ip Men. That was Ip Men's answer to him.If it protected my centerline, then no. But, that seems very strange to use a right fook sau vs right hook. I would never use that. Your (Yip Man's) choice would be chasing hands in my opinion.
This is why I was interested in the question, "Besides dodging, what's a WC guy's solution to deal with a hook punch?"
