1. Look at the date. Judging from the date of the outer packaging, the date of the real Changyu wine is printed, while most of the fake Changyu wines are printed.

2. Look at the anti-counterfeiting logo. This is also the most important point. Many brand wines will have rice moisture sensitive anti-counterfeiting technology on the bottle. Just wipe it with water and display the anti-counterfeiting logo.

3. Look at the trademark. The trademark of authentic Changyu dry red wine is very clear. There is a Y symbol in the trademark pattern and a small five-pointed star above it.

4. Look at the capacity. Authentic Changyu dry red wine is mechanically filled, with a general capacity of 75 ml, while fake products are more or less likely to be filled by hand.
