Why did the murderous list kill fat people?

it's because it cooperates with Taoist practices. According to the query of the movie "The Evil List", the Fat Gang often broke the evil-avoiding spell made by Mr. Feng Shui for the male master, and was killed by evil spirits. Bad List is a rare classic in Hong Kong horror movies. The film tells the story that Zhang Jinqiang, who has been unable to find a job, came to a building as a security guard because of a newspaper that appeared out of thin air. Since then, his colleagues around him have died tragically one after another, and his pregnant wife has become eccentric. Zhang Jinqiang is forced into a desperate situation by an evil force.
