Yue Yi: From Wei to Yan, The Legend of the Rise and Fall of the General Who Conquered Qi

Brief Introduction

Yue Yi was an outstanding military strategist and politician during the Warring States period. His life story is primarily recorded in Sima Qian's Records of the Grand Historian: Biographies of Yue Yi (Shiji · Yue Yi Liezhuan). As a descendant of the famous Wei general Yue Yang, Yue Yi fled to the state of Yan due to internal political strife in Wei. Under the patronage of King Zhao of Yan, he rose from a guest minister to General-in-Chief, leading a five-nation alliance to defeat the powerful state of Qi, creating a miracle in the military history of the Warring States. However, due to his achievements alarming the ruler, he spent his later years in exile in Zhao, ending in a sigh-worthy conclusion. This history is not only a record of military victory but also a typical microcosm of talent mobility and ruler-subject relationships during the Warring States period.

Core Knowledge Points

1. Origin and Move to Yan: Yue Yi was originally from Wei. To avoid disaster, he left Wei and came to Yan. At this time, King Zhao of Yan was eager to restore his state and wipe out past humiliation, building the Golden Terrace to recruit talents. Yue Yi was thus heavily utilized and appointed as Vice Minister. This process reflects the characteristic of the Warring States period where "scholars have no fixed master."
2. Five-Nation Attack on Qi: In 284 BC, Yue Yi was appointed as General-in-Chief, commanding the joint forces of Yan, Qin, Zhao, Han, and Wei to attack Qi. This was the largest multi-state joint military operation of the Warring States period, aimed at weakening Qi's hegemonic status.
3. Great Victory at Jixi: The alliance crushed the Qi army west of the Ji River, and King Min of Qi fled and was killed. Yue Yi pursued the victory, capturing over 70 cities of Qi within half a year. Only the cities of Ju and Jimo remained unconquered. Qi was nearly destroyed, and its national strength suffered a devastating blow.
4. Suspicion and Flight to Zhao: After King Zhao of Yan died, King Hui of Yan ascended the throne. Due to previous grievances between Yue Yi and King Hui, the latter listened to slander and sent Qi Jie to replace Yue Yi as commander. Fearing assassination, Yue Yi fled to Zhao and wrote the famous "Letter to King Hui of Yan" to clarify his intentions, demonstrating his political wisdom.

Exploration of Ruler-Subject Relationships: The Shiji specifically includes the "Letter to King Hui of Yan,"* showcasing Yue Yi's rational attitude of neither submitting nor retaliating when faced with suspicion. This deepens the theme of "scholars die for those who understand them" and contrasts the employment strategies of King Zhao of Yan and King Hui of Yan.
