The place name Yu 楡in the inscription on the Dabao gui (□ bronze food vessel) actually refers to the hunting ground of Yu referred to in late Shang oracle inscriptions connected with hunting. This territory once belonged to Xiaochenyu 小臣俞, a courtier of King Zhou of the Shang dynasty, but following the suppression of Luzisheng's rebellion in the early Zhou dynasty, was annexed into the private territory of Duke Shao 召公奭, roughly located in present day Gouyuting 句窳亭in Feicheng County 肥城縣, Shandong Province. The "Seven Bronzes of Liangshan" were therefore really excavated at a location somewhere near Feicheng, north of Liangshan 梁山. The territory of Yu at the foot of Taishan泰山belonging to the Shao clan of the state of Yan was similar in nature to that of Bengtian 祊田in the state of Zheng 鄭and the "eastem capital of Xiangtu" of the state of Wei 衛, which were places for ritual purification used by the eastern states to assist the Zhou kings when they made sacrifices to Taishan 泰山. The establishment of such places was associated with the king's inspection tours of the eastern territory. These tours of the whole kingdom were not, however, completely in accordance with the rites. As far as can be seen from extant records , kings Cheng 成, Kang 康and Mu 穆 of the Western Zhou dynasty were the only kings who actually toured and inspected the eastern territory.
