The book of destiny and the red thread.
According to legend, Yue Lao possesses a sacred book of marriage, where the names of all fated couples are written. Next to it he keeps invisible red threads, with which he binds those people together from birth.
The red thread:
- Can be stretched

But it never breaks.
In Chinese tradition, this thread is tied to the ankles of people destined to meet, a key difference from the later Japanese version.
Origin and legend of Yue Lao
The best-known account of Yue Lao appears in the work Xu Xuan Guai Lu, written during the Tang dynasty.
The story narrates that a young scholar named Wei Gu met one night an old man reading a book under the moonlight. The old man was Yue Lao. When asked what he was reading, Yue Lao explained that it was the record of predestined marriages.
Yue Lao also showed him a bag full of red threads, which he used to bind destined couples together.
The old man revealed to Wei Gu who would be his future wife. The young man, incredulous and upset by the prediction, attacked a girl who had been pointed out to him as his destiny.
Years later, Wei Gu married a noblewoman. When he lifted the veil during the wedding, he discovered a scar on her forehead: the same wound he had caused in his youth.
Destiny had been fulfilled.
