Yi Long, whose real name is Liu Xingjun, was born in Dezhou, Shandong Province in 1987. Because of his passion for martial arts novels, his father told Yi Long and his sister martial arts stories since childhood, and her sister listened to them, but Yi Long believed them. His father promised that "when you grow up, I will take you to XX Mountain to find XX masters", which was his initial imagination of "Wulin". Yi Long's elder sister, Liu Can, used to be a judo player in the local sports school. She came back from practicing movements every day, and Yi Long was the object of sparring. Therefore, her elder sister was also the first teacher on the martial arts road in Yi Long. Yi Long's performance in culture class was very good, and she was always the top three in her class. At that time, Yi Long's sister was admitted to the city sports school, and there was no extra money for Yi Long to study at home. Yi Long, who was only 13 years old, went to work alone in other places in order to reduce the burden on her family and support her sister to study. In order to save extra money when working, Yi Long eats steamed bread when he is hungry, and sleeps in Internet cafes and roadside when he is tired. Half of the money he earns is sent home, and the other half is reserved for studying kung fu to continue his dream. On the way to work, Yi Long once met a master. The master thought that Yi Long's original name was not suitable for his future martial arts career, so he named him Yi Long according to birthdates in Yi Long.
Due to long-term fatigue and turbulence, Yi Long once fainted in a waiting room of Henan Railway Station. It was this fainting that made him encounter a turning point in his life. When he woke up, he found that there were several monks standing in front of him, who woke up Yi Long. From then on, Yi Long followed the masters to live a life of practicing martial arts while performing arts. After more than a year, Yi Long finished learning Shaolin Kung Fu, and they found that Yi Long had an absolute talent in practicing martial arts. With them, I was also a buried talent, so I recommended Yi Long to a master who practiced Wing Chun Boxing. Two years later, the master recommended Wing Chun Boxing to others. In eight years, Yi Long's footprints spread all over more than a dozen provinces in China. Yi Long worshipped more than a dozen masters and practiced Shaolin, Tai Chi, Wing Chun, boxing, wrestling, Sanda and Muay Thai successively. In 27, he won the Foshan International Wing.
