Zhang Fei, a prominent military general of the late Eastern Han dynasty and Three Kingdoms period, stands as one of three sworn brothers alongside Liu Bei and Guan Yu. Their bond, forged in the Oath of the Peach Garden, forms a central pillar of the narrative—a solemn commitment to restore the Han dynasty through unbreakable loyalty.

Hailing from a modest background in Zhuo County, where his family worked as butchers and wine merchants, Zhang Fei possessed exceptional bravery, immense physical strength, and formidable martial prowess, earning him the title "General of the Tiger’s Might." His nature was marked by a fiery temper, impetuousness, and a rough, straightforward demeanor, yet these traits were matched by profound loyalty to his brothers and their shared cause.

A significant flaw was his relationship with alcohol; his drinking often ignited his temper and clouded his judgment. This weakness led to grave failures, such as the loss of Xiapi Castle when, intoxicated on forbidden wine, he allowed Lü Bu to invade and seize the stronghold.

Among his legendary exploits, his stand at Changban Bridge remains iconic. Serving as rear guard during Liu Bei’s retreat, he faced Cao Cao’s pursuing army with only a few dozen men. His thunderous challenge and fearsome appearance caused the enemy vanguard to hesitate, buying time for Liu Bei’s forces to escape—an act of solitary bravery etched into folklore.

After the establishment of the Three Kingdoms, as he prepared to avenge Guan Yu’s execution, Zhang Fei was assassinated by his own subordinates, Zhang Da and Fan Jiang. They struck as he slept, compelled by his harsh discipline after he threatened to execute them for failing to produce mourning attire for his troops on time. They delivered his head to Sun Quan.

His legacy endures as that of a fierce and loyal warrior, a symbol of raw courage and dedication, securing his place among the most revered heroes of the era.
