How to judge authentic Lai Maotai liquor:

1. Look for the brand "Kweichow Moutai Co., Ltd." to be the authentic one.

2. Make sure the trademark has "Moutai trademark" to have an authentic and good taste.

3. Look for Moutai’s unique anti-counterfeiting logo. Each bottle of Zhenlai Maotai liquor has Moutai’s unified and unique series of anti-counterfeiting logos on the bottle mouth for easy identification. The anti-counterfeiting mark is baked with high temperature fire and has 4 black spots on the four corners.

4. Look for the gold thread. There is a hidden gold thread on the mouth of the Laimao liquor bottle. After opening, the word "opened" will appear on the bottle mouth. After opening, it cannot be restored to the position before opening.
