Liu Yin
Liu Yin was Liu Yao's son by his probable first wife, Princess Bu, while he was still the Prince of Qin. He had an older brother, Liu Jian (劉儉). When Liu Jian was nine and Liu Yin was four, the emperor Liu Cong saw them, and was very impressed by Liu Yin. He told Liu Yao to make Liu Yin his heir. Liu Yao responded that he was just an imperial prince and should not reverse the proper order of heirship. Liu Cong instead told him that due to his contributions to Han Zhao, he was unlike other princes, and that he should make Liu Yin, who he felt was more talented, the heir. He therefore created Liu Jian the Prince of Linhai and created Liu Yin as the heir to Liu Yao. As Liu Yin grew up, he became strong and skillful at horsemanship and archery, and was so quick in his reaction that he was compared to a whirlwind.
