The character "fen" is a major criterion for identification. The upper part of the character is on the bottle cap, and the lower part is on the bottle body. The upper and lower parts match without misalignment, and the "氵" has a curvature. Since it is laser engraved, the words on the bottle will not be easily erased. The workmanship of fake wine is obviously much rougher, and the "氵" is obviously straight. In some fake wines, the word "fen" is completely on the bottle cap or completely on the bottle body.

Trademark identification The trademarks of Zhenfenjiu include the Gujingting trademark, the words "FENJIU" and "Fenjiu", which have a bumpy feel when touched. In addition, the patterns and fonts on the bottle are neat and clear. .
