Chinese Grappling: CHIN-NA, Vol.1 (Literary Links to the Orient)

Chin-na is one of the most convenient of the martial arts to study. It requires no great amount of practice space and no special or protective clothing or devices. It does, however, require a reliable practice partner. Training by oneself produces no true progress, only a false sense of confidence. Two or more practice partners is even more advantageous. The greater the variety of the partners, the more experience the student will gain and the quicker and more completely the techniques will be mastered.
