At present, there are two extremes in misunderstanding about the liquid wallpaper project. One is to pursue big brands and think that big brands are guaranteed. In fact, liquid wallpaper is still a new project in China, and there are no well-known brands at all, so it is easy to be misled. The second is to pursue low prices. If it is a high-quality product produced by a legitimate enterprise, their price difference is not big, which has no impact on our cost at all. If there must be something wrong with the lowest-priced product, how can he save money if the price is so low? If the product quality is too poor, how to make a high-quality engineering quality effect? This is "a clever woman can't cook without rice". If he says the product is good and the price is surprisingly low, who will believe it? This is basically a trap. You can cheat how you want.
