In fact, there are some scams in jewelry sales that people can't think of. For example, if you buy something in a lottery, many people will be curious to see it. The merchant took out some things that were not well packaged. When you pick it up and try it on, you will be told that the price is tens of millions, which will scare you. Sometimes these smooth little things will be scared away or even broken. Although the probability is very low, they are originally "not for three years, but for three years." Small probability is enough.
