Yes, when I was in college, I worked as a commentator in promoting Quan Wei. Many people don't believe that the shelf life of pure juice can be 2 1 day. That's because the daily transportation mode of C preservation in Quan Wei is very unique, and the temperature of the whole cold chain product is always controlled at 7 degrees Celsius, which will not deteriorate. So I feel fresh every time I drink it, like grapes and orange juice. I like it very much. It's also very troublesome to squeeze at home every time. Drinking c every day is enough.
