As a fan of online literature, I can't make an accurate prediction of the box office of a movie. However, we can draw some conclusions from some relevant reports and data. 'Hello Lee Hwan-Ying' was a film directed by a Chinese director and actor, Wu Jing. It told the story of a young woman looking for her father's murderer. After the film was released in mainland China, it had achieved good box office results. So far, its box office had exceeded 4.6 billion yuan. In comparison, Detective Chinatown 3 was a detective film that starred Tang Ren, Liu Haoran, and others. It told the story of a mysterious murder case and was released in Chinatown in the United States. The movie had achieved great success worldwide. So far, its box office sales had exceeded 5.8 billion yuan. Although Hello Lee Hwan-young might have performed better than Detective Chinatown 3 at the box office, many factors needed to be considered to predict the box office success of a movie, such as the quality of the film, audience preferences, market competition, and so on. Therefore, the final box office success still depended on the market's reaction and the audience's willingness to buy.
