You don't have to believe it. China has a history of selling jewelry by lottery for several years. Most of them are in the supermarket environment. Shopping receipts are used for lucky draw. Jewelry is basically around 1000 yuan and 10000 yuan, and then it is basically low discount, 10% discount and 20% discount, which can make consumers feel that they have found a bargain.
So the jewelry is real, and the price may not be as high as the target.
