Yi Long, whose real name is Liu Xingjun, 1987, is from Dezhou, Shandong. Because of his passion for martial arts novels, my father told martial arts stories to Yi Long and his sister since childhood. My sister listened, but Yi Long believed them. His father promised that "when you grow up, I will take you to XX Mountain to find a master of XX", which was his initial imagination of "Wulin". Yi Long's sister Liu Can used to be a judo player in the local sports school. She comes back from practicing movements every day, and Yi Long is the object of sparring. Therefore, her elder sister was also the first teacher on the martial arts road of Yilong. Yilong achieved good results in the culture class and has always been the top three in the 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 is only 13 years old, supports his sister to study and goes out to work alone in order to reduce the burden on her family. In order to save extra money by 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 earned was sent home, and the other half was reserved for studying kung fu and continuing 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 his birth date.

Due to long-term fatigue and bumps, Yi Long once collapsed in a waiting room of Henan Railway Station. It was this fainting that brought him to a turning point in his life. When he woke up, he found several monks standing in front of him. They woke Yi Long. From then on, Yilong followed the masters to live a life of practicing martial arts while performing. 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. Yi Long was also a talent who was buried with them, so he was recommended to a master who practiced Wing Chun. Two years later, the master recommended him to others. In eight years, Yilong has traveled all over more than ten provinces in China. Yi Long has worshipped more than a dozen masters and practiced Shaolin, Tai Chi, Wing Chun, boxing, wrestling, Sanda and Muay Thai. In 2007, he won the Foshan International Wing Chun Championship.
