What are archways and archways? What's the role?

Archway is a kind of building with columns like doors, which are generally relatively high. In the past, it often appeared as a decoration at intersections or main roads. There are several kinds of arched doors: wooden arched doors, stone arched doors, glazed arched doors, mixed arched doors of wood and stone, and mixed arched doors of wood and brick. At present, temporary memorial archways made of bamboo and wood are also very useful in some large-scale celebrations. The archway is a unique landscape of the ancient city of Beijing and a unique carrier of China's architectural art and culture. There were 65 archways in Beijing during the Ming and Qing Dynasties, including 6 glazed brick archways, 42 wooden archways and 7 stone archways/kloc-0. There are only six archways on the existing streets, namely, four archways on the Guozijian Street, the glazed brick archway in front of Dongyue Temple on Lu Shen Street outside Chaoyangmen and the archway in front of the East Palace of the Summer Palace. Memorial archway is a building erected in the workshop of Huangdi's hometown in feudal society to commend meritorious service, discipline, virtue and loyalty and filial piety. There are also some temples that use memorial archways as mountain gates, and some are used to mark place names. Also known as the memorial archway, it is a gatehouse-style memorial building, which promotes feudal ethics and flaunts merits. The memorial archway is also an affiliated building of the ancestral hall, which shows the noble character and great achievements of the family ancestors and has the function of offering sacrifices to their ancestors.
