According to the search results, Suyin, played by Li Bingbing, does not appear in Meg 2: The Trench, as the sequel reveals that her character died after the events of The Meg. The exact cause of her death is not revealed, and the details of what happened in the years between the two movies are not provided. The absence of Li Bingbings character is explained within the movie, but it is unclear why Suyins character was killed off-screen, as it limits the possibility of Li Bingbing returning for future sequels. It is possible that Li Bingbing may have retired from acting or been busy with other commitments. Although Suyins death is briefly discussed in Meg 2, it is not expanded upon, and her absence is only hinted at in a brief scene where Jonas Taylor and Meiying discuss her absence.
