I didn't know you meant the corridor.
Commonly used in multi-storey buildings such as pavilions in ancient buildings in China.
There is also a nickname called "beauty".
In ancient times, boudoir women could not go downstairs easily. When they are lonely, they can only lean on the chairs around the patio, look out at the outside world, or peek at the entertainment downstairs, so they call this kind of chair "beauty leaning".
