What are the martial skills (kung fu)?

In combat, tai chi chuan uses evasion, stickiness and sensitivity rather than brute force.
The muscles remain relaxed at all times and the body moves as one whole unit (neigong).

There are many tai chi chuan martial skills in the syllabus, including:

1. Shuai jiao (take downs)
2. Chin na (seizing)
3. Jing (internal power)
4. San sau (fixed sets)
5. San da (freeform combat)
6. Form application
7. Weapons
8. Self defence

Even though many of these skills are common to different styles of kung fu, a tai chi chuan student must perform them in a tai chi chuan way.
The application of tai chi chuan always follow the guidelines presented in the Tai Chi Classics.
