The Red Thread of Fate (Chinese: 姻緣紅線; pinyin: Yīnyuán hóngxiàn), also referred to as the Red Thread of Marriage, and other variants, is an East Asian belief originating from Chinese mythology.[1] [2] It is commonly thought of as an invisible red cord around the finger of those that are destined to meet one another in a certain situation as they are "their true love".[3] According to Chinese legend, the deity in charge of "the red thread" is believed to be Yuè Xià Lǎorén (月下老人), often abbreviated to Yuè Lǎo (月老), the old lunar matchmaker god, who is in charge of marriages.[1] In the original Chinese myth, it is tied around both parties' ankles, while in Japanese culture it is bound from a male's thumb to a female's little finger. Although in modern times it is common across all these cultures to depict the thread being tied around the fingers, often the little finger. The color red in Chinese culture symbolises happiness and it is also prominently featured during Chinese weddings, such as having both bride and groom wear red throughout the entire procession or at some point during the marriage rituals.
The two people connected by the red thread are destined lovers, regardless of place, time, or circumstances. This magical cord may stretch or tangle, but never break. This myth is similar to the Western concept of soulmate or a destined partner.
