Former Jiu Jitsu master Tian Hong introduced the rules of ground fighting to Brazil. Maeda, known as the "Count of Fighting", is an expert in ancient jujitsu and Kodoku Judo. Maeda is very good at fighting and participates in various competitions to test his skills. He often participates in all-contact fighting competitions. He is a small man, 5 feet 5 inches tall and weighs 154 pounds. Nevertheless, he is highly skilled, and it is said that he only lost once in his life. 19 14 entrusted by the Japanese government, Maeda came to Brazil to help Japanese immigrants set up resettlement sites. At this time, he got the help of casto Gracie, a successful businessman with a strong political background. Maeda became good friends with the Scottish immigrant, so he passed on his JIU jitsu knowledge to Gracie's sons.

Casto's eldest son, Carlos Gracie (1902 ~ 1994), was trained by Maeda. Records show that Carlos studied with Maeda for a limited time, maybe only two to four years. It seems impossible to become a jujitsu master in such a short time. According to historical records, Maeda taught the Gracie brothers the basic techniques of Jiu Jitsu, the general strategies that wrestlers should master and the methods to win and control fights. These strategies are Maeda's own experience in unrestricted fighting. In addition, Gracie adopted Maeda's training method-free fighting training, and the philosophical thought of using real fighting as the verification of technical practicability. But many jujitsu and its application in actual combat were developed by Gracias himself. Carlos taught Jiu Jitsu to his brothers osvaldo, casto, Joao, Yuge and Airiau. 1925, Gracie established Gracie School in Rio de Janeiro. Maeda continued to travel in Brazil and around the world, while the young Gracis worked out the technical details. Maeda never thought that Gracie would stand out and become the greatest fighting system in modern times. After Carlos retired, he began to be a manager for his brother, "becoming a nutritionist" and developed Gracie's diet.

Helio gracie (1908 till now) is the youngest of the brothers. He is thin and often dizzy. The doctor doesn't allow him to do strenuous exercise. Airiau was disciplined by Carlos and often watched his brothers practice jujitsu. One day, Carlos didn't train a student alone. Airiau volunteered to replace his brother, and Airiau made up for his lack of strength with technology. The learner was impressed by Airiau's skills and asked Elliot to teach him formally. While he was teaching, Airiau discovered many technologies.

At that time, many technologies were not tested in actual combat. Airiau modified these technologies to adapt to a small fighter like him (140 lb). He added new technologies and deleted those that required great efforts or were not practical in actual combat. Like Maeda, the Gracie brothers openly challenged all sects, regardless of their weight and time. Once, Gracie actually advertised in the most famous newspaper in Brazil: "If you want to break your head and bones, you can contact us Gracie."

Unlimited combat has almost no rules and time limits. Unlimited fighting will only end when you knock down your opponent or make him surrender. Gracie accepted many challenges and tested her skills in actual combat. The Gracie brothers, led by Eliot, constantly master the most direct and effective methods to deal with the enemy. Elliot became the best player among the brothers-the family champion. He became a reformer, developed new techniques and strategies, and completed the evolution from "Japanese Jiu Jitsu" to "Brazilian Jiu Jitsu".

Airiau took part in the professional competition. He challenged Japanese judo and jujitsu players, professional wrestlers, boxers and road fighting experts. He is the first contortionist in the western world to beat Japanese contortionist Takagi with 1932.

This is the first time that he has participated in a Jiu Jitsu competition, and it is also the first time that he has participated in a Jiu Jitsu suit. Aliao and Langmu wrestled together on the ground. After the bell rang for a few seconds, Langmu applauded. Elliot also played the longest game in modern times. He competed with his former students for 3 hours and 45 minutes without rest. He also challenged boxing champions primo canela and ezzard charles, world champion joe louis and later boxing champion Ali.
