赵郡李氏, the Cui family of Boling
博陵崔氏, the Cui family of Qinghe

荥阳郑氏, the Wang family of Taiyuan

隴西李氏 were the seven noble families among whom marriage was banned by law. Moriya Mitsuo wrote a history of the Later Han-Tang period of the Taiyuan Wang. Among the strongest families was the Taiyuan Wang. The prohibition on marriage between the clans issued in 659 by the Gaozong Emperor was flouted by the seven families since a woman of the Boling Cui married a member of the Taiyuan Wang, giving birth to the poet Wang Wei. He was the son of Wang Chulian who in turn was the son of Wang Zhou. The marriages between the families were performed clandestinely after the prohibition was implemented on the seven families by Gaozong. The Zhou dynasty King Ling's son Prince Jin is assumed by most to be the ancestor of the Taiyuan Wang. The Longmen Wang were a cadet line of the Zhou dynasty descended Taiyuan Wang, and Wang Yan and his grandson Wang Tong hailed from this cadet line. Both Buddhist monks and scholars hailed from the Wang family of Taiyuan such as the monk Tanqian. The Wang family of Taiyuan included Wang Huan. Their status as "Seven Great surnames" became known during Gaozong's rule. The Taiyuan Wang family produced Wang Jun who served under
Emperor Huai of Jin. A Fuzhou based section of the Taiyuan Wang produced the Buddhist monk Baizhang. ==Family==
