The Light Touch or the 4 Ounce Bridge

Dear Sifu, ILC brothers and sisters,

I was wondering what your thoughts and experiences are of the coveted "light touch" or the "4 ounce bridge" in martial arts (mainly arts that are considered "soft styles" I suppose).

My personal experience is that sometimes, it is easy to "keep running away" / keep retreating into a corner when chasing this particular quality at the contact point (perhaps using inappropriate means no doubt).

Peace and harmony,
Joey
