After the 19th century, the gallery refers to the public display place where the audience appreciates art works. The nature of the exhibition is basically the same as that of the art museum. It may be smaller than the art museum, but it is more targeted to works or art schools. In addition, with the development of capital market economy, the trend of art commercialization has been strengthened, and painting merchants specializing in art products also came into being. A place where artists display and sell art is also called a gallery.
