1. Trademark. The word "Fen" of the genuine product is golden and transparent, and there is no contact with the surrounding circle. The English letters on both sides of the trademark are clear.

2. Bottle cap and bottle body. The genuine bottle cap and bottle body have obvious traces of laser printing, with detailed touch and clear handwriting.

3. At the bottom of the bottle, there are a series of numbers on the bottom of Fenjiu bottle, which basically start with FJ. When you see other letters, it is likely to be fake wine.
