 During the reign of Wu Yi of Shang, Duke Jili of the now renamed state of Zhou attacked and evicted the Di presence from lands north of Bin with the support from the Shang court, and made Yiqu subject to Zhou instead.During the reign of Duke Wen of Zhou, Chancellor Jiang Ziya sent ambassador Nangong Kuo to negotiate an alliance with Yiqu, who assisted Zhou in evicting their rival Guifang, while occupied the fertile Longdong region for themselves.This allowed the Yiqu population to prosper, and after learning agricultural techniques and city building from the Zhou people, became significantly influenced by Zhou culture.
