As someone who loves to read novels, I don't have real-time box office data or market research functions, so I can't predict the box office revenue of the 2019 National Day film. However, based on what I know about the situation, we can make some analysis and guesses. Generally speaking, the box office earnings of movies during the National Day period were relatively high because it was a traditional peak tourist period. The audience usually chose to go to the cinema to watch movies on this day. In addition, the National Day period was also the time when some blockbusters were released. These blockbusters often had higher box office earnings. The different characteristics of the three tributes could also affect their box office earnings. For example, some works might attract a large audience while others might focus more on word of mouth and communication effects. Therefore, if the production quality, story content, publicity, and other aspects of these works were done well, they might also achieve higher box office earnings. It was impossible to accurately predict which film would have a higher box office. Many factors had to be taken into account, including audience preferences, market competition, and so on.
