The Unique Skills of Brazilian Jiu Jitsu;

JIU jitsu practitioners in Brazil often practice throwing techniques, upper suppression techniques, post-control techniques, surrender techniques based on various advantageous positions, escape techniques from unfavorable positions, and defense at lower positions.

In a lower position, various defensive postures (guards) are the biggest characteristics that distinguish Brazilian Jiu Jitsu from judo, Sambo, wrestling and other wrestling martial arts. The so-called "defensive posture" refers to all kinds of postures in which you control your opponent's body with your legs and fight back when you fall to the ground. The defense in Brazilian Jiu Jitsu is mainly divided into three categories: open defense, closed defense and semi-defensive posture.

Corresponding to the defensive posture is the guard passing technique, that is, getting rid of the control of the opponent's low defensive posture to gain a favorable position-they are like two sides of a coin, which constitutes the conversion system of offensive and defensive techniques in Brazilian jujitsu competition.
