Rope-shaped ornaments woven with five-color silk thread, the five-color rope that children carry in their hands during the Dragon Boat Festival, is also called longevity rope.
Tang Han's "Dragon Boat Festival": "A hundred ropes wrapped around the arm color tube."
Original note: "Make an arm tied with a rope with colorful strands, a long-lived strand."
Song Gaocheng's "Things for Jiyuan, Customs for a Hundred Years": "There are hundreds of cables today, that is, Zhu Suo's legacy, which was built in the Han Dynasty and was originally used to decorate the portal. Today, people use their arms, which is the same mistake."
