Maybe it's me, but after reading some of the comments, a baseline definition of "chasing hands" seems in order.
I've always understood it as, and teach it as, -intently focusing on the opponents action, [usually fast punches]with the sole intent on stopping said action, without consideration to an offensive response.
I.E., myopically focused on endless paaking to someone delivering an endless string of chain punches.
This is usually a result of 'fear of being hit' rather than lack of training. However, the training that I see in many schools is.. well, lacking.
In training, I stress the importance of being a good, 'bad guy'. If the drill is getting punched in the mouth, then punch them in the mouth.. DON'T stop short. It's their job to remove the threat. Following through doesn't allow the bad guy to subconsciously develop a bad habit during a real encounter, nor does it cheat the 'good' guy' out of realism and distancing. Also, if their mind is elsewhere, they also miss learning the feel of being hit. Something they will learn in a real fight. [which in my experience's, never hurts much -at that time, anyway]
If this is what is meant by chasing hands, then it will almost always end with getting tagged, and in Wing Chun is on the top of being verboten.
