春秋五覇
Some years later, Duke Mu of Qin heard about Baili Xi and inquired of his whereabouts. Upon the advice of his minister, he famously redeemed Baili Xi with five pieces of goatskin. In order to escape detection from the king of Chu, he sent a low-ranking official to meet the king and had Baili Xi transported to Qin in a prisoner's cart. Once in Qin, Duke Mu accorded Baili Xi with great respect and appointed him as his right-hand man. Baili Xi was already in his 70s by that time. He recommended his old friend Jian Shu to Duke Mu. Together, the duo played a major role in Qin's rise to power. Thus, Duke Mu was able to attain "hegemon" status and became one of the "Five Hegemons of the Spring and Autumn period".
