Hemp cloth banner(功布)
A hemp cloth hung upon a long bamboo pole and used as a banner carried before a funeral bier at the time of barin (Kor. 발인, Chin. 發靷, departure of the funeral procession from the home to the burial site).
Gongpo is made from a piece of loosely woven hemp, measuring 90 centimeters long, and is made by folding and stitching one of the sides to hold a bamboo pole and attaching a pair of tassels. The banner pole, made of bamboo, has a finial at the top. This banner is used to wipe dust or earth off the top surface of the coffin before covering it with myeongjeong (Kor. 명정, Chin. 銘旌, a banner bearing the name of the deceased and his government position) and lowering it into the grave pit.
During the funeral procession gongpo is also used to inform the mourners following the funeral bier of the situation around the route leading to the burial place. The gongpo bearer informs the mourners behind him of the condition of the road, whether it is downslope, upslope, or cut off, by waving the flag to the right or left or raising or lowering it.
