The Eight Energies (Bā Jìn, 八劲) of Taijiquan are the core expressions of internal power:

1. Peng (ward off), expansive and uplifting; 

2. Lü (roll back), yielding and redirecting; 

3. Ji (press), concentrated forward power; 

4. An (push), sinking and rebounding; 

5. Cai (pluck), sudden pulling down; 

6. Lie (split), spiraling, tearing force; 

7. Zhou (elbow), close-range striking; 

8. Kao (shoulder), full-body bumping. 

Together, they embody Taijiquan’s balance of softness and strength, defense and attack.
