At one point, someone says that "Chinese New Year is coming soon" (the date of Chinese New Year varies, but it is always in January or February), but later Jerry Khoo receives a text message and says that "terrorists flew a plane into the tallest building in the US" (September 11, 2001). Since Chinese New Year occurs at the end of the movie, perhaps the filmmakers added the second line as a memorial to 9/11 but forgot that it was the wrong time of year in the movie.
