1, dial the phone number on the anti-counterfeiting label to preliminarily identify the authenticity.

2. Call the after-sales phone of Fenjiu Group and check the production date to identify the authenticity.

3. Observe the appearance of Fenjiu. The whole case of Fenjiu for 30 years is integrated, and it is impossible to open the bottle without unpacking. So if it's not for personal use, you can carefully distinguish it on the wine box.

4. Identify the color of the coating. There is a coating under the wine box. After the coating is scraped off, there is a string of numbers in three colors. If it is not tricolor, the wine may be fake.
