It has been suggested by scholars such as Annette Juliano and Arthur Cotterel that having a horse-breeder as their ancestor may imply that the Yíng family had partial relation to nomadic tribes. As late as 266 BC, it was remarked by a noble of Wei that they shared customs with the Rong and Di tribes; the Central Plains states seemed to hold Qin culture and other peripheral states like Yan and Chu in low regard, due to the marginal location of their states. Qin was the second state after Zhao to adopt cavalry tactics from the nomads. Following the collapse of Zhou Dynasty, the Qin state absorbed cultures from two of the Four Barbarians from the west and north, which made the other warring states see their culture in low esteem.
