He was the second of two child rulers of Qin known in historiography as "Chuzi".
[2][3] He is also variously referred to as Duke Chu of Qin (秦出公), Shaozhu of Qin (秦少主), or Xiaozhu of Qin (秦小主) (Shaozhu and Xiaozhu both mean "Young Lord").
Duke Jian reigned for 15 years and was succeeded by his son, Chuzi's father Duke Hui II, who reigned for 13 years and died in 387 BC.
Just two years later, in 385 BC a minister in the government, Jun Gai (菌改), rebelled against Chuzi II and the duchess.
He led his forces to escort Duke Xian, who was at the time exiled in the Wei state, back to Qin, killed Chuzi II and his mother and installed Duke Xian on the throne.
