The registered trademarks of Fen liquor are "Fen" brand and "Gujingting" brand. The registered trademark of "Fen" brand is a circle with the word "Fen" printed in calligraphy. The word "Fen" is golden and transparent, and there is no contact with the surrounding circle. The English letters on both sides of the trademark are clear. The trademark of "Gujing Pavilion" consists of the front pattern of Gujing Pavilion and the words "Gujing Pavilion". In the figure, except for the two black corners that are tilted, there are 16 vertical black lines on the pavilion top, which represent the width of the pavilion tile, and the width and width should be evenly spaced, and the gold lines drawn are also clear. There are three gold words "Gujing Pavilion" on the forehead of the golden pivot under the pavilion eaves. The designs of Fenjiu and Gujing Pavilion are relief printing, with exquisite printing, bright color and neat trimming. Both sides of the registered trademark are decorated with the first prize medal of the 1915 Panama Games with an outer diameter of 15mm and the gold medal pattern of the 1963 national wine tasting. The word "book" in the "registered trademark" is intentionally written as "friend".

The fake "Fenjiu" has a dull surface and is in contact with the circle. The patterns of the two medals are printed roughly, and the handwriting is generally vague and dull. The black lines on the pavilion top are not 16, and the word "Gujing Pavilion" under the pavilion eaves is hard to read clearly. The writing of the word "Book" on the registered trademark is different from that of the real one.

(2) Identification of neck label

The neck label of Fenjiu is neat and clear. The neck label of fake "Fenjiu" is printed roughly, and some people mistakenly write the word "wine" as the word "sprinkle". The handwriting of the neck label of ceramics is unclear, and the red color permeates each other seriously.

(3) bottle cap identification

The bottle cap of Fenjiu in glass bottles is made of imported aluminum, and the thread anti-theft cover is printed with the pattern of Gujing Pavilion, neat and clear, with additional decoration. The anti-theft cover is yellow, printed with the poems of Xinghua Village and Du Mu in Tang Dynasty, and equipped with the sealing label of "Fenjiu". The inner wall of the bottle cap is silvery white, with elastic white hard plastic pad inside, and the seal is neat. There is a red arrow on the thread of the outer wall of the bottle cap to indicate the opening direction, and the word "open" is written in English. Fenjiu in a pipa-shaped porcelain bottle is sealed with a plastic cover and a rubber cap, and a sealing strip with the words "China Famous Wine" is added; There are colored pictures of Xinghua Village and Du Mu's poems on the bottle, and there are lace on the top and bottom.

The fake "Fenjiu" bottle caps are made of different materials, and the pattern on the cover of Gujing Pavilion is not clear, and it falls off. The inner wall of the bottle cap is dark or painted yellow, and the inner pad is paper pad or dark yellow plastic pad, and the sealing is irregular. There is no opening indicator arrow and English on the outer wall of the bottle cap.

Fenjiu liquor is colorless, clear and transparent, with no precipitation and suspended matter. The color of fake wine is not correct, white or turbid: the real Fenjiu wine is pure, mellow and refreshing, with a refreshing aftertaste, a natural and harmonious wine body and a long aftertaste after drinking. Fake "Fenjiu" has a mixed fragrance and different alcoholicity, and the content of substances harmful to human health often exceeds the standard.
