Jo Jeong (1555-1636), art name Geomgan, was a member of the Pungyang Jo clan who served as a volunteer-army leader in the Imjin War. Houses associated with him still stand in Nakdong-myeon, Sangju, and he is honored as a leading ancestor of the Sangju Pungyang Jo.
His collected works, Geomgan Seonsaeng Munjip, include Jinsa Illok, a diary of 1592-1593 that mainly records volunteer-army activity in the Sangju area. The collection was published in Sangju in 1740 (Yeongjo 16) by two fifth-generation descendants, with proofreading by Yi Gwang-jeong, and its 114 printing blocks are a North Gyeongsang cultural property.
Yangjindang in Sangju was built in 1626 by moving a house from Cheonjeon-dong in Andong, his wife's home district, as the ridge-beam inscription shows, and was designated Treasure No. 1568 in 2008. Ojakdang was first built in 1601 and moved to its present site in 1661; it is a North Gyeongsang folk cultural property.
Jinsa Illok is a diary mainly recording volunteer-army activity in Sangju in 1592-1593. The printing blocks of his works are described as a North Gyeongsang cultural property item (No. 656).
Yangjindang (Nakdong-myeon) is a raised-floor courtyard house of nine by seven bays that was repaired in 1807. Ojakdang (Seunggok-ri, Nakdong-myeon) retains its main house, men's quarters and ancestral shrine and is thought to be older than its neighbor. Cheonggan Pavilion (Unpyeong-ri) was designated North Gyeongsang Cultural Property Material No. 558 in 2009.
Cheonggan Pavilion in Sangju, presumed built around 1650 by Jo Ye (1608-1661), is described as a place of study for descendants of the Geomgan-gong main line of the Pungyang Jo.
