Although in the movie, the old man once saved the heroine Cui Hua, but at the beginning of the operation preparation, he was attacked by a group of people, and finally fell to the ground seriously, unable to participate in the operation. At the end of the film, although Cui Hua's operation was successful, the old man has passed away, which makes Cui Hua and the audience feel very sad.
However, the end of the film also implies that there may be a sequel, so whether the old man has other storylines remains to be shown in subsequent films.
