In the northwest desert, in the border town of Yeshanguan, there is a dilapidated mountain villa, Yangzhuang. As horse bandits often harassed the villa, the villagers suffered greatly. After discussion, the whole village decided to send Cao Gen (played by Qiu Lin) and Fan Jian (played by Luo Jiaying) to the town to invite swordsmen to protect Yangzhuang. Cao Gen and Fan Jian, who were facing obstacles everywhere, met the down-and-out old swordsman Gu Du Qiu Bai (played by Liang Jiaren) in desperation. Gu Du Qiu Bai, who had retired from the rivers and lakes for many years, agreed to save Yangzhuang at the request of Cao Gen and Fan Jian, but needed to find two more swordsmen as helpers. So, the lame and frustrated swordsman Gui Jiao Liu (played by Li Yu) and the fledgling young swordsman Su Gaier (played by Shi Xiaolong) joined the team to save Yangzhuang, and the three of them headed towards Yangzhuang. The martial arts comedy film "The Swordsman's Legend", directed by the famous director Yuan Hongbing, has a unique cast. "Super Girl" He Jie and "Kung Fu Boy" Shi Xiaolong play the male and female protagonists respectively, and veteran film and television actors such as Luo Jiaying, Liang Jiayan, and Li Yu are willing to play supporting roles. In addition, many online singers have joined in to make friendly appearances.
