This is not true. Because people come and go at the station every day, if you buy jewelry, you will not carefully check the authenticity, and it is easy to buy fakes. Moreover, there are people at the station, and it is difficult to guarantee whether the source of jewelry is clean or not, and there is no jewelry appraisal book. I don't know who to look for when I buy fake goods. Therefore, the station only used people to sell a lot of fake jewelry.
