http://www.tsomtom.com Wing Tzun Lat Sao "free fighting Driils" Demo By Sifu Yannis Simeonidis. A very important aspect of TSOM TSOM WT training is Lat Sao and free fight training respectively. Sifu Yannis joined together the Lat Sao in a logical way in order that the WT students can always visualize a fight in its various stages. During the practice sessions different attacks are simulated and are met and countered with specific WT techniques. The central role of tactical as well as visual reflexes is the main characteristic of the TSOM TSOM Lat Sao. Almost any fighting situation can be simulated and practiced by using specific evasion and transformation maneuvers within the Lat Sao cycles.
