Guo Nanhong entered the field of martial arts films after "Dragon Gate Inn" set off a craze for martial arts films in Taiwan. Although Guo Nanhong has been directing artistic films for ten years, he changed his style and directed the martial arts film "The Sword King of the Generation". The film starred Taiwan's chief martial arts stars Tian Peng and Shangguan Lingfeng, and the result was a blockbuster. This box-office martial arts film that sold well made Kwok Nanhong the third "million-dollar director" in the Hong Kong film market after Zhang Che and Hu Jinquan. The film has also become one of the representative works of Taiwanese Mandarin martial arts films. "The Sword King of the Generation" is an ancient costume sword martial arts film with no clear background. In this film, he used Tian Peng, a newcomer to the film industry at that time, as the first male lead. The film tells the grudges between various martial arts factions, and the story is relatively conventional. However, since the martial arts design follows the path of new martial arts schools such as "Drunken Man", combining the northern movements with the martial arts movements of Japanese samurai films, the audience also looks fresh and interesting.
