Red String of Fate in Chinese / Japanese...

姻緣紅線 is the legendary red string of destiny that binds all soul mates or lovers together.

In ancient Chinese culture, a mythological matchmaker named 月老 (Yuè Lǎo) was the controller of the fate that led lovers to meet. He did this by tying a celestial red string to the ankle of each person. Sometime during their life, they will meet and marry as fate dictates.

While the origin of the red string comes from China, it has spread to other parts of Asia (such as Japan, where it's known as 赤い糸).

This literally translates as “the red string” or “the red thread” in Japanese, but the real meaning is much deeper...

In Japanese culture, it's believed that fate, destiny, or karma joins lovers by an unseen string, tied around one little finger of each. 赤い糸 is how soul mates find and are drawn to each other.

The Japanese concept of the red thread of fate, by most estimations, comes from Chinese folklore, where it's known as 姻緣紅線. The only difference is that in China, the celestial red thread is tied around the ankles of the lovers (versus what is usually represented as the pinky finger in Japan).
