Disease (? -300 years ago), also known as Gui Lizi and Yan, was an imperial clan and general of the State of Qin in the middle of the Warring States, an illegitimate child, Qin Huiwen's half-brother, and his mother was Korean. [1] Because of his resourcefulness, he was nicknamed "think tank" and was honored as "the former teacher" by later generations. He assisted Qin Wanghui, Qin Wuwang, Qin Zhaowang and other Qin monarchs. The name of scorpion is disease. Because of living in Zhuanli (once said, now Weinan, Shaanxi), it is called Zhuanlizi. Later, he served as the General Staff (Assistant Chief of Staff of Daliangzhou), and was called General Sickness. Later, it was sealed in Yandao County, Shu County (now Yandao Town, Yingjing County, Sichuan Province), and it was named Yan Jun, known as Yan Jijun in history. Later generations took the fief as their surname, so it was also regarded as one of the roots of Yan's family.

He is good at diplomacy and military affairs. After Qin Wuwang expelled Zhang Yi, he appointed Gui, his uncle with outstanding military exploits, as the right prime minister, and the one who was good at military strategy as the left prime minister. The two men brought out the best in each other and carried out a series of wars to expand the territory of Qin State, which laid a solid foundation for the later unification of China by Qin State. Sima Qian's "Historical Records" Tai Shigong said in the preface: "Qin is so busy with the eastern princes that it is a policy to bury Li." In the first year of King Qin Zhao, Gui Lizi was still the prime minister.
