If you open the box, you don’t need to drink it. If you drink it and it is fake wine, it means you are weak. The obvious difference is the bottle cap. The genuine Niulanshan bottle cap has a uniform color, while the fake Niulanshan bottle cap has a bright color. What can I say? You can't tell from the bottle cap. But there is one place where it is easiest to judge, and that is to look at the north side of the wrapping paper. The fake Niulanshan trademark is pasted by hand, while the genuine Niulanshan logo is pasted by machine. You can tell right away. This is the real Niulanshan. You can see that the glue applied by the machine is relatively even and there are horizontal lines on it. This is the fake Niulanshan. You can tell at a glance that it was applied by hand and has spots. To judge the authenticity of Niulanshan, if you are a bottle, this is how you judge. When you encounter fake Niulanshan while drinking in a restaurant, remember to protect your own rights and must compensate. I have finished speaking, have you understood it?
