Jade bracelet, also known as "spear", "bracelet" and "armband", is a round ornament worn on the wrist. Bracelets have a long history and originated from the transition from matriarchal society to paternal society. According to relevant documents, both men and women wore bracelets in ancient times, with women as a symbol of marriage and men as a symbol of status or the nature of work. In ancient society, people also thought that wearing bracelets could ward off evil spirits or welcome good luck.
