As mixed martial arts becomes more and more popular in China, the author, as a mixed martial arts enthusiast, increasingly realizes that the talent, skills, difficulty, endurance, perseverance and luck required by this sport are unmatched by other sports. Through the growth process of a Chinese mixed martial arts athlete, this book further reveals the sport's technical and tactical training, comprehensive skills, competition preparation, athlete protection mechanism and the pre-match and behind-the-scenes of the competition, hoping to change the stereotype that this sport is barbaric and dangerous in the eyes of ordinary people. Perhaps this is the first novel about mixed martial arts with a popular science nature. I hope it can help fans gain a glimpse of the secrets and improve the viewing experience to a certain extent.
