When was Cai Mao of the Three Kingdoms born?

Cai Mao (date of birth and death unknown) was born in Cai Zhou, Xiangyang (now Xiangyang, Hubei). At the end of the Eastern Han Dynasty, a famous family in Jingzhou, the son of Cai Yan, and his aunt (Cai Yan's sister) were Wen's wives. The elder sister and the second sister married Huang and Liu Biao successively and became their second wives. In the first year of Chuping (190), Liu Biao succeeded Wang Rui as the secretariat of Jingzhou. At that time, thieves prevailed in the south of the Yangtze River, and Cai Mao helped Liu Biao pacify Jingzhou. During his service for Liu Biao, he served as the magistrate of Jiangxia, Nanjun, Zhang Ling and other counties, and Liu Biao served as his strategist when he was awarded the title of Zhennan General by Han Ting. After Liu Biao died of illness, he supported Liu Cong's succession. When Cao Cao invaded Jingzhou in 208 AD, he joined forces with Kuai Yue to force Liu Cong to surrender to Cao Cao. Later, he became an official under Cao Cao, and worked as a corps commander, Sima, and a captain of Changshui, and was named Hanyang Hou Ting.
