Bracelet, also known as "hairpin", "bracelet" and "arm ring", is a ring-shaped ornament worn on the wrist. Besides gold, silver and jade, it is also made of rattan. 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.
