As far as I know, the price of gold in Clety is relatively low in China. It seems that their home is mainly cost-effective. You don't have to worry about the quality of gold. After all, people are regular jewelry stores, and there will definitely be a special quality inspection agency to test them.
Personally, I suggest that these gold, jewelry and other accessories are actually brand-free, and there is no need to pursue those so-called brand goods, such as Chow Tai Fook and Lao Fengxiang. As long as the landlord confirms that it is genuine, you can buy it with confidence.
