The Oracle Bone form of 友 depicts two right hands. A common interpretation is two right hands held together in a handshake; as handshaking was a common ritual of camaraderie, respect and goodwill and is still used today in many cultures. Another popular interpretation is that 友 depicts two hands side-by-side in companionship or extended to help each other. Both interpretations demonstrate the care and love amongst friends. Through 友, we can see how Chinese culture draws a correlation between morality and friendship.
