Bo Yi 伯夷 ("Uncle Yi") was a loyal subject to the last king of the Shang dynasty 商 (17th-11th cent. BCE). His personal name was Yuan 元, courtesy name Gongxin 公信. He was the oldest son of the lord of Guzhu 孤竹 from the family Motai 墨胎. He was not designated to succeed his father, but his younger brother Shuqi 叔齊 refused to mount the throne. Both thus expressed a high degree of filial piety and are venerated by the Confucians as an example of social etiquette, righteousness and loyalty. Both left their homeland and followed the Viscount of the West 西伯, the eventual King Wu of Zhou 周武王 (11th cent.), founder of the Zhou dynasty 周 (11th cent.-221 BCE). During the attack on Shang, they, as subjects of Shang, admonished King Wu not to destroy the kingdom of Shang, but without success. Disappointed, they left and withdrew to the mountains where they finally died of hunger. There is another Bo Yi, who is also written 柏翳 or 伯益 and was a minister of the mythical emperor Shun 舜.
