the color of the right side of the anti-counterfeiting logo will fade after heating, and it will recover after cooling. Identification of original box of jiannanchun.

First of all, the identification of the whole box of Jian Nanchun starts with code spraying. Real wine is coded above the seal, which can be easily scraped off with nails, while fake wine is often coded first and then sealed, and cannot be scraped off below the seal. Next, look at Jian Nanchun's trademark. The trademark of fake wine is rough and printed on the box, and the trademark of real wine is laser carved on the box, which has obvious concave-convex feeling and clear texture. Finally, look at the sign of solid-state fermented liquor with pure grain. After comparison, it is clear that the sorghum ear of real liquor is clear, and the leaves below are fine and grid-like after amplification. The ears of fake wine are sparse and messy, and the leaves below are also dotted.
