The whole bottle of real wine has a registered trademark, with four small characters of "LU ZHOU LAO JIAO CO.,LTD Co., Ltd." and three big characters of "Tequ Liquor" in the middle, and a circular trademark pattern and color composed of wheat ears in the middle; The font and bottle shape of fake wine are very similar to those of real wine, but there are some differences in the registered trademark "Luzhou Brand". Generally, I dare not use the "Luzhou brand" label and use other font sizes. Look for the words "Luzhou Qu Distillery in Sichuan, China" or "Luzhou Qu Distillery in Sichuan" on the real wine trademark when purchasing. The words "Luzhou Qu Winery" are printed on the sealant sleeve of the bottle cap, and the words "China Luzhou Qu Winery Special Qu (No.1)" are printed on the metal anti-theft cover. Fake wine has no sealant sleeve, even if it is really bottled, it can be identified by this method. In addition, it can be distinguished from the new procedure of trademark.
