劉胤
When Liu Cong's successor Liu Can was overthrown by Jin Zhun in 318, Jin massacred members of the Liu clan in the capital Pingyang (平陽, in modern Linfen, Shanxi). Liu Yin's grandmother Lady Hu and his uncle lost their lives, but Liu Yin fled. However, he was captured by or sold to the Heiniyuju (黑匿郁鞠) tribe as a slave. After Liu Yao defeated the renegade general Chen An in 323, Liu Yin revealed his identity to the chief, who was surprised and respectfully deliver Liu Yin back to Liu Yao. (It is not clear where Heiniyuju was or why Liu Yin waited until Chen's defeat to reveal his identity to the chief; it could have been that Heiniyuju was initially a Chen ally, and while Chen was, prior to his rebellion, nominally a Han Zhao general, Liu Yin might have been concerned about being detained by Chen as a bargaining chip.) By this time, Liu Yao, who had assumed that Liu Yin was dead, had created his younger son Liu Xi crown prince. He considered replacing Liu Xi with Liu Yin, since Liu Yin was the original heir, and he considered Liu Yin general material. However, after opposition by Liu Yin's uncle Bu Tai (卜泰) and another official Han Guang (韓廣), Liu Yin personally declined to replace Liu Xi, instead stating that he could use his abilities to assist Liu Xi. Liu Yao agreed, and he let Liu Xi remain crown prince, while granting Liu Yin special honors, including requiring Liu Xi to yield to Liu Yin as an older brother in ceremonies, rather than for Liu Yin to yield to Liu Xi as the crown prince. The relationship between the brothers appeared to remain cordial until their deaths. He also posthumously honored Liu Yin's mother, Princess Bu, as Empress Yuandao.
