The cinema in Qujing, Yunnan Province opened on the first day of New Year's Day, but it didn't open this year.

A cinema is a place where movies are shown to the audience. In the early days, movies were shown in cafes, teahouses and other places. With the progress and development of movies, there have been cinemas specially built for showing movies.

The development of movies-from silence to sound and even stereo, from black-and-white film to color film, from ordinary screen to wide screen and even dome screen and ring screen-has greatly changed the shape, size, proportion and acoustic technology of cinemas. Cinema must meet the technological requirements of film screening and get the good visual and auditory effects it deserves. Film has become an argument after dinner.

On December 1st, 217, the Standard for English Translation and Writing in Public Service was officially implemented, stipulating that the standard English name of a Cinema is Cinema or Movie Theater.

The auditorium is the main part of the cinema, and the screen is the basis for the design of the auditorium. The size of the screen determines the capacity of the audience. The larger the screen, the more people can accommodate the audience, and the smaller the screen of the auditorium with fewer audiences, so the size of the auditorium actually depends on the size of the screen.

The shape of the screen determines the shape of the audience hall, especially for new forms of movies. Different varieties have different shapes of screens, the screen size of large-field movies determines the height ratio of the audience hall, the screen of ring-screen movies determines that the audience hall must be round, and the screen of dome-screen movies needs a dome-shaped audience hall and so on. Generally, the cinema audience hall with flat screen is rectangular or trapezoidal, and the ground has a certain slope.
