Vitamin C tablets of Shanghai Yangshengtang are genuine counterfeit products, which are on the anti-counterfeiting list of the Industrial and Commercial Bureau. It's no use checking the authenticity.

So fake things are not guaranteed. Think about the ingredients in them yourself. We have VE and VC in Shanghai Yangshengtang, and the goods are only a few dollars, which is not as good as the protection of medicinal VC.

Now the industrial and commercial bureau is checking VEVC in Shanghai Yangshengtang. If there is one in the store, you can find the Consumers Association or report it directly to the industrial and commercial department.
