King Li of Zhou was a foolish and immoral ruler who oppressed the people, and was overthrown by the Xirong. Qin Zhong sought to avenge King Li of Zhou and, by imperial decree, led a campaign against the Xirong. He killed countless enemies, but in the end was killed by them himself. Qin Zhong's son, Duke Zhuang, led the five tigers of the Qin clan to avenge his father and swept across Xirong. For his achievements, King Xuan of Zhou made him Grandee of the Western Frontier and granted him Xiquanqiu as Qin territory. Duke Zhuang of Qin moved the Qin capital to Xiquanqiu.
During the campaign against the Xirong, he learned firsthand the true reasons behind their conflict with the Western Zhou. From then on, he laid down his weapons, and no war broke out for more than forty years. Taking advantage of those four decades of peace, Duke Zhuang of Qin reformed official conduct, improved the people's livelihoods, resettled refugees, built a new city, opened trade, and established markets, bringing a brief period of prosperity to Qin.
