Oath of the Peach Garden

The Oath of Peach Garden (義重桃園 or 桃園三節義) was an oath by which the three fighters Liu Bei, Zhang Fei, and Guan Yu became sworn brothers in a ceremony amid peach blossom trees. This historical act binded the three most crucial men of the future Shu-Han Kingdom of China and is often alluded to as a true symbol of fraternal loyalty.

They said "We were born on seperate days, but let us die at the same day, same time and same place." Guan Yu and Zhang Fei were both outlaws and were scorned by everyone, so Liu Bei took them as brothers.
