Using Quick and Painful Joint Locks, a threatening opponent can be almost effortlessly rendered unable to continue a fight.

Chin Na, which means "seize and control", is the study of how to control your opponent through joint locks and pressure point manipulation. Almost all Chinese martial arts styles have Chin Na in them and include it in part of their training. However, Chin Na can be a valuable addition to any martial arts style. Japanese Jujitsu and Aikido are based upon the same principles as Chin Na, and since the Chinese culture significantly influenced them, it seems probable that Chinese Chin Na also influenced their indigenous martial arts. Chin Na is also well suited to self defense and law enforcement since the techniques can be used to control an assailant without causing injury or death.

Chin Na taught at the Seven Star Praying Mantis Kung Fu School is from Dr. Yang Jwing-Ming. The techniques include about 60% White Crane and Tiger Claw Chin Na from Dr. Yang's first master, Cheng Gin-Gsao, and 20% Long Fist Chin Na (mainly from Eagle Claw, Praying Mantis and Cha Chuan styles) from Dr. Yang's third master, Li Mao-Ching. The remaining 20% Dr. Yang developed through his many years of martial arts experience. Chin Na is available to learn from books and videos, however, when learning Chin Na, feeling is 80% of the technique, which means getting the feeling of accurate control cannot be obtained from reading books and watching videos. The class will give students this hands-on touch to get the correct feeling that is required to perform good Chin Na.
