The ending of Aaron Kwok's movie 'The Murderer' in Hong Kong was different from the original. In the original ending, the murderer was Aaron Kuo's fellow disciple, while in the Hong Kong version, it was another person named "Lin Mingyuan". In the Hong Kong version, Lin Mingyuan planned a murder case against Aaron Kuo because of his grudge with Aaron Kuo. In the end, he successfully killed Aaron and handed the evidence to the police. During the police investigation, Lin Mingyuan was eventually found dead. It should be noted that the Hong Kong version and the original ending are different in terms of storyline and character setting. Therefore, the specific situation needs to be analyzed according to the full version of the movie.
