Does anyone know of a credible source for the history of southern styles such as Bak Mei, Wing Chun, Lung Ying, Hung Gar, Yau Kong Moon, and Fu Hok Yau Kong? All of these styles report a very similar history. Some people refer to them as Southern Shaolin styles while others say there never was a Southern Shaolin temple. Has anyone ever gotten to the bottom of all this? Are there any reliable works on this in English??? Please let me know.
