I work in Shuangshui Town, and Vida does have a factory there, that's for sure, but the packaging of these things can be imitated, so it can't be used as a confirmation standard, and the product code can't prove anything, but generally large supermarkets don't sell fakes. In fact, you can judge whether it is genuine or not by your own feelings. Price, feel and packaging are the most direct means, I hope I can help you. If you think there is a problem, you can also go to the supermarket or 12593 to complain.
