This is a round mat used for purposes such as drying grains, and its edge is slightly raised to prevent the grains from spilling out. It was made by weaving rice straw and hemp skin. It was also placed on the ground when hulling rice with a wooden mill. There are two holes on one side to tie a string for convenient storage, while the bottom and edge were adorned with a star-shaped motif, two concentric design and saw tooth motifs.
