Historically, Yue Fei’s pinky promise serves as a testament to the value placed on it. Folklore and legends warn of consequences associated with pinky linking and severance. Today, the pinky promise and pinky swear endure as gestures of commitment and playfulness. In relationships, pinky rings symbolize unity, and during weddings, the exchange of pinky promises signifies an unbreakable bond.
