Daecheong (Korean: 대청) is a large wooden floor between the rooms of the main building in a traditional Korean home, called hanok.
It frequently appeared in larger houses where upper-class people such as yangban lived.
Daecheong is used as a place that symbolizes status and authority, as a space for performing ancestral rites or as a place to worship a vassal called the seongju (성주).
[1] It is located in the center of the house and has a central function that dominates the other rooms in terms of space.
In addition, the inside is not visible from the yard, and mats are laid on the floor.
