BJJ is a grappling martial art that focuses on ground fighting, submission holds, and positional control. It is often associated with the use of leverage and technique to overcome larger and stronger opponents.

BJJ's emphasis on ground fighting and submissions, in contrast to the striking techniques of many traditional martial arts. Additionally, the philosophy of using technique and leverage rather than relying solely on strength is a key differentiator.

The belt system in Brazilian Jiu-Jitsu (BJJ) consists of several colored belts, each representing a practitioner's skill level and experience. The order of belts, from beginner to advanced, is as follows:

1. White Belt: This is the starting point for all practitioners. White belts are beginners who are learning the fundamentals of Jiu-Jitsu.

2. Blue Belt: After a period of consistent training and demonstrating a solid understanding of the basics, a practitioner may be awarded a blue belt. This belt signifies a deeper understanding of techniques and an ability to apply them during sparring (rolling).

3. Purple Belt: Purple belts have a high level of technical proficiency and are often able to chain together various techniques seamlessly. They have a more developed understanding of strategy and are considered intermediate-level practitioners.

4. Brown Belt: Brown belts are advanced practitioners who have honed their skills to a high degree. They often contribute to the learning environment by helping others and may start developing their own unique style of Jiu-Jitsu.

5. Black Belt: Achieving a black belt in Brazilian Jiu-Jitsu is a significant milestone and represents a mastery of the art. Black belts are typically skilled in both offense and defense, have a deep understanding of the underlying principles of Jiu-Jitsu, and may begin to contribute to the evolution of the art.
