Liu Biao
Liu Biao initially favoured his elder son Liu Qi because the latter resembled him in appearance. Liu Cong later married the niece of Liu Biao's second wife, Lady Cai. Due to this, the Cai family was naturally inclined to support Liu Cong, and they often spoke ill of Liu Qi in front of Liu Biao. Liu Qi fell out of his father's favour and heeded Zhuge Liang's suggestion to leave Jing Province's capital Xiangyang and travel to Jiangxia Commandery. On the other hand, Liu Biao loved Liu Cong deeply and wanted to let his younger son succeed him as the Governor of Jing Province. As a consequence, a rift developed between Liu Cong and Liu Qi.
