Lei Kyu Chi Da ( fighting without a bridge)
"Lei Kyu Chi Da (it means fighting without a bridge) This has to be learnt before you ever touch Chi Sau. Basically it is fighting from a distance, learning to close the distance through correct stepping techniques. Most importantly it is IMHO learning to fight a "real" Fight using Wing Chun. In all reality for the most part only a few moves are needed from Wing Chun to fight at a distance, Daap, Gou Laan, Laap Ngoi Lim, Ji Mh Choih, and Fu mei being what I would think of as the bare essentials. Guangzhou's wing chun covers this with its Sahp Yih Sik and San Sik fighting, before ever engaging in Chi Sau."
how many have experience in this, and what are some of the ways you use this strategy in fighting?
