What is Tvea (Door)?

According to wikipedia, a door is a moving structure used to block off, and allow access to, an entrance to or within an enclosed space, such as a building or vehicle. In Khmer Martial Art Trea means entrance for fighting or is called direction for fighting.

According to Motto of Kun Khmer Boran, There are five structures 

1. Tvea (Door)
2. Kol 
3. Me Sorm
4. Kbach

•  As mentioning above, Tvea means the entrance for fighting or called directing for fighting. 
• Kol is the limitation of point for fight or how to point a target to fight. 
• Me Sorm is the trial before fight, it is similar to military exercises.
