One theory is that during the reign of Emperor Chuiren (who ascended the throne in 29 BC), Naomi Su Mi and Dangma Chusu had a famous fight. Their battle is a combination of fighting and wrestling. Since then, some people have absorbed wrestling techniques and developed into the present sumo sport; Others summed up their fighting experience in fighting and developed it into jujitsu, which in turn evolved into judo.

Another statement seems to be more acceptable to everyone. According to legend, as early as the12nd century, China and Tang fought hand in hand and spread to Ryukyu and Japan. In the first year of the Apocalypse of Emperor Xi of Ming Dynasty (162 1), Chen Yuanyun, who studied martial arts at Shaolin Temple in Henan Province as a teenager, went to Japan with Shan Fengxiang, the envoy of Feng Dao, Zhejiang Province, and became the guest of Tokugawa Shande, the owner of the tail fan. Later, he taught monks at the Kung Fu Temple in the south of Edo. At that time, there happened to be three martial artists, namely Shi Weimen, Chibei Jirozaemono, Jiemen, who stayed in the temple and studied under Chen. After their painstaking research, they obtained the mystery of Shaolin Wushu. Later, the three of them went to various places to give lectures and continued to learn and improve, which led to the extensive development of Jiu Jitsu in Japan, and formed many schools and their own systems through folklore, and celebrities came forth in large numbers.

"Father of Judo" Jana Jgoroh

But by the middle of the 19th century, Japan was in a period of great turmoil. 1868, the Tokugawa shogunate fell, and Mu Ren ascended the throne of the Emperor and was renamed Meiji. Since then, Japan has embarked on the road of capitalist development. With the change of social system, it is more and more popular to imitate the advanced scientific civilization of western European and American countries, and Jiu Jitsu is also rejected by people because it is considered feudal. Jiu Jitsu artists are affected, some are depressed and secluded, some are aristocratic guards, and some are jugglers. The fallen soldiers rely on jujitsu to harass, bully civilians and extort money in society. At that time, Jiu Jitsu became a tool for some hooligans to fight, which was despised and disliked by all walks of life, and Jiu Jitsu faced decline.

In the tenth year of Meiji (1877), Jana Jgoroh (1860~ 1938), a student of Imperial University of Tokyo (now Tokyo University), was weak in childhood and was often bullied by her peers, so she decided to learn jujitsu out of the desire to keep fit. After several years of hard work, we have conducted in-depth research on all schools, regardless of other people's opinions, learning from each other's strengths. Mr. Ghana's JIU jitsu theory and technology have become perfect. He takes winning or losing, self-discipline and self-cultivation as self-discipline, and self-cultivation as the purpose, that is, cultivation is more important than practice. At the same time, in order to distinguish it from the previous jujitsu, the name "Judo" occasionally used by believers was adopted.

"Judo" Beats "Jiu Jitsu"

In February of Meiji 15 (1882), Mr. Ghana moved to Yongchang Temple in Shimonoseki, Tokyo, and took the academy as the Dojo to train judo, teach students and start judo-centered training activities. This Yongchang Temple has also become a pioneering place for "Japanese to spread judo in Kodokan". Later, Kodokan became more and more influential and gradually became the training center of Japanese judo at that time.

However, at that time, Japanese jujitsu circles criticized, accused and confronted the professor of Judo in Ghana. They think that judo in the Kodo Pavilion is an armchair strategist and unrealistic thing, which may not be superior to jujitsu in technology, so people often go to the Kodo Pavilion to make trouble. Jiu Jitsu and Judo have become two factions, trying to compete with Judo. In May of Meiji 19 (1886), a decisive battle between judo and jujitsu was held at the initiative of Tong Yong, the police chief, and he personally presided over it. This battle is actually related to the success or failure of judo, which has aroused great concern of the people. At that time, judo and jujitsu each had 15 people for a decisive battle. As a result, Kodokan won a great victory, especially the decisive battle between Shiro Xixiang, who is famous for conquering various schools of Jiu Jitsu, and Taro Shinjima, the master of Jiu Jitsu in A Jiu of the East Palace School, ended in Shiro Xixiang's victory. This not only established Kodokan Judo's position in the society, but also won the support of the society and unified the field of Jiu Jitsu because it overwhelmed Jiu Jitsu with absolute superiority in skills. With the active support of the police department, Japanese judo has finally developed into a sport and embarked on the road of prosperity.

The International Judo Federation still clearly stipulates in the first article of its constitution: "The International Judo Federation recognizes Judo founded by Yana Jgoroh." He is naturally recognized as the "father of judo". It is precisely because of Mr. Ghana's contribution to the development of judo that judo has flourished in Asia, Europe and the United States and become a worldwide sport.

So there is a record of judo in the Water Margin.
