Zhuge Jin was born in Yangdu County (陽都) in Langya Commandery (琅琊), in present-day Yinan County, Shandong. He was the eldest of three brothers and became orphaned at a young age. His uncle raised him and his siblings. When Cao Cao invaded Shandong in 195, his family was forced to flee south to Jing Province and his uncle soon died of illness. After his two sisters married into notable families with numerous relations in the area, Zhuge Jin started his journey to the east.
Service under Sun Quan
After the Yang Province warlord, Sun Ce, was assassinated, Zhuge Jin was referred to Sun Ce's successor, Sun Quan, and became his personal secretary (长史; secretary of a general was expected to participate in military operation during Han dynasty). He was soon transferred to be the Central Major (中司馬), however.
Zhuge Jin joined Lu Meng's invasion of Jing Province, and was promoted to the General Who Pacifies the South for his performance during the campaign. When the Battle of Yiling broke out, Zhuge Jin wrote a letter to Liu Bei, asking him to abort the operation, but Liu Bei refused. Since Zhuge Jin's younger brother, Zhuge Liang, was the most trusted officer under Liu Bei, someone told Sun Quan that Zhuge Jin was colluding with the forces of Shu Han, however, Sun Quan openly announced that no matter what the rumor said, Zhuge Jin would not betray him, just as he would never betray Zhuge Jin.
During Zhuge Jin's later years, he was promoted to the rank of Grand General (大将军) and Left Commander (左将軍). He participated in several military campaigns against the state of Wei, but suffered defeats in most of them.
