General cases are handed over to the economic investigation, either the case involves a large amount of money or it is difficult to handle! At present, if counterfeiters do not admit it, sometimes the industrial and commercial departments will be deadlocked in handling cases. After all, the industrial and commercial departments have no right to restrict personal freedom, and can only check the accounts of the goods themselves, and at most check the illegal businesses, which is certainly not as strong as the economic investigation department of the public security system. So, as you said, if this case is to be classified as a difficult case, there must be at least one investigation process. It can't be said that the chamber of commerce and industry is difficult, so it is normal to wait for a few months. From the perspective of three months, there may not be something fishy.
