Plaque is a unique commercial language and cultural symbol in my country. It is a comprehensive art work that integrates Chinese language, Chinese calligraphy, traditional Chinese architecture and sculpture, and is a comprehensive work of art that combines ideological and artistic qualities. It is widely used in prominent locations in palaces, archways, temples, businesses, residences and other buildings to convey information about imperial power, culture, characters, beliefs, commerce, etc. to people. Calligraphy and painting are different. Generally, calligraphy and painting are hung indoors to show the owner's cultural taste and cultural accomplishment. They are mainly written on paper or silk and should not be hung outdoors!
