What are the names of the two stones under the old door?

Door pillows are located in the doorways of buildings. In order to support the door leaves, piers are often set at both ends of the lower sill under the door, and small holes are drilled on the piers to place the door shafts. This pier supporting the door shaft is called "door pillow". Door pillows are made of stone and wood, mostly stone. Shimen pillow is also called "door pillow".
