According to the shortest period stipulated by the International Jiu Jitsu Federation, it takes at least 2 years for leucorrhea to rise to blue belt, 1.5 years for blue belt to rise to purple belt and 1 year for purple belt to rise to brown belt. For ordinary practitioners, it takes 4-5 years of continuous study and training to reach the purple belt.

The position of the belt is only the stage symbol of JIU jitsu practitioners, but it does not fully represent the actual combat level of this person. It doesn't mean that the high position is necessarily better than the low position. In the arena, cases of Jiu Jitsu Blue Belt defeating Black Belt and Purple Belt surrendering to Black Belt abound.

At present, Brazilian Jiu Jitsu is still a minority event in China, and there are not many players who can reach the level of black belt:

According to incomplete statistics, there are only about ten black belts in China, such as Zhang Tiequan, Shi Yujing, Du Fu, Wu Chengda, Kong Xiaofeng,, and so on.
