1. Insufficient publicity: The Legend of the Grand Commander may not be sufficiently publicized, resulting in many people not knowing enough about it and lacking the willingness to watch movies.
2. Film quality: The production level of The Legend of the Master may not be as good as other films of the same type, including the plot, actors' performances, picture effects, etc., which may affect the audience's evaluation and viewing experience.
3. Subject audience: The Legend of the Guard mainly tells the story of Zhang, a historical figure, which may attract a specific and relatively small audience. Moreover, the content of the story is far from modern society, which may make some viewers find it difficult to resonate.
4. Competitive pressure: When the legend of Grand Commander is released, it may face competition from other films of the same type with high reputation and popularity, resulting in poor box office performance.
The above are only possible reasons, and the specific situation may be different due to factors such as time, place and market environment.
