Some film and television genres, such as science fiction, mythology, historical figures, etc. There have been great changes in the shape of characters, so it is impossible to achieve the goal only by painting some oil paints, so it must be solved by plastic makeup. For example, in Andy Lau's Slimming Men and Women, the figure of the protagonist is fat and thin, with great changes and strong contrast. This situation can only be made up by plastic surgery. Without this makeup, this genre can't be made into a movie.
