There is a kind of martial arts, that is, people click their heads and die. What's it called?

This is not a specific martial art. . It's just a killing technique. . . It's like locking the throat. . . You can directly kill the enemy. . . China martial arts never admire this kind of thing (of course, some martial arts books will mention these techniques). . . China's kung fu competition is always a matter of time. . . This kind of neck-breaking only appears in real killing and being killed, which is extremely cruel. People in that kind of special forces are expected to learn these skills specially, and then cooperate with appropriate combat techniques to exert the power of terror.
