Born in a karate family, Hirakawa Truth, a Hong Kong-Japanese hybrid, was devastated by the loss of his father and lovelorn. He became stronger and stronger under the hell-style training and encouragement of the master played by du Wenze, and the biggest enemy turned out to be himself. Du Wenze, who is a karate master himself, is no longer funny when he becomes a director. He incarnates as a producer, director, screenwriter, lead actor and martial arts director, insisting on shooting serious martial arts fighting themes, and invites his own master, Seven-Duan Kakata Baozhao and martial arts enthusiast ou Jintang to take the stage to create a unique charm. The guide cylinder is like picking up a karate robe, purely trying to challenge yourself.
