"Silent film" or "pantomime". An image work (such as a movie, TV series, short film, advertisement, etc.). ) only contains background music and character movements, without dialogue and character dubbing. This form of image expression is called "silent film" or "pantomime". Mime originated in the silent film era. In the silent film era, due to the limitation of technical level, dubbing or dialogue can not be added to the film, and only background music, text introduction and character movements can be used to express the plot and character. At the same time, pantomime is also a very old performing art form with high artistic value.
