Bow knot (concentric knot) is a kind of knot that looks like a butterfly, and is usually applied to shoelaces, hair accessories or clothes. Its production materials, shapes, sizes and playing methods are different, but its appearance is beautiful and generous, which not only reflects China's ancient cultural beliefs and strong religious color, but also reflects people's beautiful desire to pursue truth, goodness and beauty.
Bows are decorated on the tobacco bags, and butterflies are homophonic with blessings, meaning that blessings are in sight and overlapping. On New Year's Eve, the elders put on hundreds of copper coins with red silk ropes as lucky money, so that children can live a long life. On the Dragon Boat Festival, colorful silk threads are woven into ropes and hung around children's necks to ward off evil spirits, which is called longevity thread. In the animal year, in order to drive away diseases and disasters, a red rope is tied around the waist.
