The method of identifying the authenticity of Fenjiu is as follows:

1. The word "Fen" is engraved with a laser between the bottle cap and the bottle neck, and it has an obvious concave and convex feeling to the touch. If it is a real Bo Fen, the upper part of the word "fen" is on the bottle cap, and the lower part is on the bottle neck. The upper and lower parts are perfectly connected and there is no misalignment. If it is a fake Bofen, the word "fen" will be unevenly distributed and obviously misaligned.

2. On the front of the bottle, the word "Fenjiu" is written in red with gold edges, focusing on the word "wine". If it is a real Bo Fen, the font printing will be clear and there will be a blank gap between the three points of water in "wine". If it is fake Bo Fen, the font printing is blurred and the three points of water in "wine" are connected together.

3. Above the word "Fenjiu" in gold-edged red letters, there is a Gujingting trademark. If it is real wine, there are 16 evenly distributed vertical lines on the top of the pattern, which are clearly distinguishable and easy to identify. If it is fake wine, the pattern will be blurry and the vertical lines will be connected together.

Introduction to Fenjiu:

Fenjiu, a famous traditional Chinese wine, is a typical representative of light-flavor liquor. Because it is produced in Xinghua Village, Fenyang City, Shanxi Province, it is also called "Xinghua Village Wine". Fenjiu liquor has exquisite craftsmanship and a long history. It is famous for its soft taste, sweet taste, lingering fragrance after drinking, and long aftertaste. It enjoys high popularity, reputation and loyalty among domestic and foreign consumers.

Fenjiu has a long history of about 4,000 years. During the Northern and Southern Dynasties 1,500 years ago, Fenjiu was highly praised by Emperor Wucheng of the Northern Qi Dynasty as the imperial wine. It was recorded in the Twenty-Four Histories, making Fenjiu famous in one fell swoop. Known as the earliest national wine and a national treasure, it is the crystallization of the wisdom and labor results of the working people of ancient China.
