... The book "CHIN NA FA" was written by Liu Jin Sheng in collaboration with Zhao Jiang. The first edition of the book was issued in July of 1936 as a manual for the Police Academy of Zhejiang province. The book was printed by the publishing house Shan Wu in Shanghai. Translated from Chinese in 2005.
"...This technique is exclusively designed for practical employment, not for decoration and show. Each man who needs to master an effective system of self-defense, whoever he may be - civilian, military man or member of police, must have this book. It is necessary to systematically drill as shown in the photos and explained in the text. In the course of time everything will turn out all right. When you suddenly encounter an enemy and you have no firearms with you, you have to enter a hand-to-hand fight. If you mastered this skill (CHIN NA), you will be able to win.
Moreover, having mastered this technique, you can sway the destiny of the enemy. You can kill your enemy, cause unbearable pain, tear his muscles and sinews, break his bones or make him unconscious for some time and completely disable him to resist.
Even a woman or a physically weak man who mastered this technique can curb a strong enemy. This technique demands deftness and skill, not brute force. It is necessary to train oneself daily to make the body flexible and nimble, but "hardness" must be hidden inside this "softness".
This method is very artful and effective. For a long time it was not passed (to other people) and was almost lost. Now we publish this rarity and pass the priceless Art to our compatriots as a gift."
