They are all genuine. Why do you say that? Because they have registered in the industrial and commercial bureau and established a jewelry brand. Just different in popularity, brand and mode. The top ten jewelry brands in China are Chow Tai Fook, Luk Fook Jewelry, Golden Supreme, Zhou Shengsheng, Zhou Dasheng, Dai Mengde, Betty Wong, Fuhui, Xie Ruilin and Lao Fengxiang. China has a Chow Tai Fook and a cottage brand with similar names, such as, Jin Dafu, Jin, etc. Let's not say whether his product is fake or not, just say that the name is opportunistic. But if we buy something, if it is affordable and worth buying, you can go to some jewelry brands and compare their prices, services, quality, craftsmanship and after-sales service. It depends on which is more cost-effective, and then decide for yourself. I don't recommend the landlord to choose any world brands. The bigger the brand, the higher the price. They are all inlaid with diamonds, platinum or 18k gold. As long as the hardware of regular brand stores is guaranteed, you can feel their software.
