Zhuge Jun, born in Langxie Yangdu (now Yinan County, Shandong Province), is a Han nationality, the son of Zhuge Yi. Ge Jun and Zhuge Liang are brothers, and Zhuge Liang is Zhuge Jun’s brother.
Zhuge Jun’s father Zhuge Lei died early, and his brother Zhuge Liang, Zhuge Jun and two elder sisters were brought up by his uncle Zhuge Xuan. Knowing that Zhuge Xuan and Liu Biao had old friends in Jingzhou, he took Zhuge Liang and Zhuge both to attach to each other. He and his brother Zhuge Liang and two sisters fled to WoLonggang, Nanyang, Jingzhou. In 207, Liu Bei made three visits to Maolu and asked his brother Zhuge Liang to come out of the mountain to help him. After his brother Zhuge Liang became Liu Bei, Zhuge still stayed in Longzhong to grow fields and spend his days. Later, his brother Zhuge Liang introduced Liu Bei and was appointed as the captain of Changshui.
