The waiter did say something, but it was basically advertised like this. Let me tell you something. Bracelets are like old styles, and those without patterns and sliders can reach thousands of gold. However, there are slides, buckles or other decorative styles, and it is impossible to meet the hardness requirements with thousands of gold in these positions. Only 960-990 gold can be used. Increase the hardness to make it stronger. (Technically speaking, it is an ingredient) So a bracelet can only reach 99.6%-99.9% pure gold content after it is melted as a whole. According to the relevant national regulations, it is not allowed to print thousands of gold. For the above reasons, most of the bracelets can't reach thousands of gold (some say that their ornaments are all four nines, which is false propaganda). You can understand the excessive promotion of shopping guides, but even the pure gold content will not be much lower than that of thousands of feet (pure gold countries require more than 99%). As mentioned above, it can be no less than 99.6%. The brand of Chaohongji (I haven't touched it, I know a little about it) should be similar to the price of thousands of gold. If I sell it to you at a price of one thousands of feet (one price for thousands of feet and one price for pure gold), the nature will be different.
