Because in addition to well-known brands such as Chow Tai Fook, Zhou Dasheng, Leofoo, Lukfook, Mengjinyuan, Safir, China Gold, Chinese Jewelry, Laofengxiang, Laomiao Gold, Jindafu, Ji Meng Jewelry, Chaohongji, Zhou Shengsheng, Hong Kong-Zhuhai, Sichuan-Hong Kong Jewelry, etc., Zhou Jinsheng and Zhou Dajin are not well-known, but they are still regular brands. Zhou Jinsheng Gold is a small brand in Shenzhen, China, but its popularity is low. With this name, people mistakenly think that it is an old brand in Hong Kong. In fact, it is only ten years old. It has no sense of design, nothing but cheap. As long as all physical stores are genuine and all brand stores have the same gold content, there is no problem of low content, and you can buy as much as you want.
