Bi Gan (c. 11th century BCE) was a prominent royal kinsman and high minister during the late Shang dynasty, traditionally regarded as King Zhou of Shang’s uncle (some sources say half-brother). He served as Shaoshi—a position akin to prime minister—and was renowned for his unwavering loyalty, integrity, and fearless remonstrance.
Baili Xi (c. 725–621 BCE) was a virtuous minister of Duke Mu of Qin during the Spring and Autumn period. His courtesy name was Ziming, and he was from Wan in the state of Chu (present-day Nanyang, Henan).
