The Different Style of Tai Chi

There are different styles of Traditional Tai Chi mainly Chen, Yang, Wu, Woo, Shun. People often question what are the differences? It is my understanding that each of these styles place a different emphasis on certain part of the Tai Chi principles or theories, thus resulted in a different postures or movements, and application techniques.  For example, Yang Style places more importance on stability, consistency and calmness while Chen Style places more emphasis on the powerful strikes and spiral effect of the force. However they all share the same fundamentals and principles of Tai Chi.
