A dispute over the family tree of one of the Tang Dynasty's greatest poets will be heard by Zhabei District People's Court.

Du Fu was regarded as a poet-saint during the Tang Dynasty (618-907). His family tree was inscribed on an old house beam and kept in Changzhou, Jiangsu Province, where it stayed, undergoing several revisions, until 2004, when it was taken to Shanghai by Du Huanrong, the oldest surviving descendant of the Du clan.
