The product design is not novel enough. According to the information of Dianping.com, Longfeng jewelry is not novel in product design, and many products are over-imitated, so gold does not buy Longfeng jewelry. Longfeng Jewelry is a jewelry brand under Shenzhen Jinzuanyuan Jewelry Co., Ltd., which was founded in the early Republic of China. Its main products are gold, platinum, palladium, diamonds, jadeite and other jewelry.
