Herring stone, also known as "living jade", can be worn by children to receive blessings and ward off evil spirits. According to folklore, old people can wear herring stones to receive blessings and ward off evil spirits. Using herring stones as bracelets or children's chest pendants can receive blessings and ward off evil spirits.
