In 1999, the national vinegar of the Tang Dynasty was purely a scam. There is no cure for the disease at all, and it is said that it can cure all diseases! If the patient has no effect, it is said that he is in convalescence and will have an effect slowly. It is purely deceptive and harmful! Some social idlers who used to engage in pyramid schemes also cheated by giving lectures. A bottle of vinegar was sold to 400 yuan, which is no different from the market 10 yuan. I hope the relevant departments will come forward to ban and stop cheating!
