Logically speaking, if the industrial and commercial department does not have a random inspection task, it cannot deduct your jewelry. Even if it has a random inspection task, it can only buy samples, which means spending money to buy jewelry from you for random inspection.
Small shops like yours are the most likely to get into trouble. The reason is that you did not pay the so-called protection fee. . .
Inspection stations encounter this kind of problem every year in their industrial and commercial spot checks. Large stores or shopping malls pay tribute to the industry and commerce every year, so every time the people at the inspection station request random inspections, the industry and commerce obstruct them in every possible way. Just go to a small shop with no background and no backstage to pick up some small items and come back for testing.
The only way is to find a relationship to settle things, really. If you open a jewelry store, your gold should be sold with a small label. Find a local testing station and spend a little money to find someone to do it for you. There is a certain connection between the testing station and industry and commerce, and I can’t go into details.
Furthermore, you said your name is not good, you have to call it Jin Dafu, let alone this name, there are very few names similar to this one that have been registered. I really don't understand what you think.
