Chin Na is the art of seizing and controlling, and is an element of all Chinese martial arts including Taijiquan. Today, most people practice Taijiquan to maintain health or cure sickness. For the last fifty years the martial aspects of Taijiquan have been ignored, and the art is now incomplete. Most practitioners no longer understand the martial applications of Taijiquan, or even that it is a martial art. For example, the concept and training methods of Taiji martial power (Jin), and how to apply internal Qi (internal energy) in the martial arts have become an unfamiliar subject in Taiji societies today. As a result, actual martial applications of Jin and Qi, such as Chin Na or Cavity Strikes, are currently not popularly known or studied.
