Meng Xin jewelry is heard of, that is, you can get pearls for free by giving coupons in shopping malls. Then let you add money to make a necklace. It's kind of like a trap. But it's not cheating, because it's all made clear to customers. Now everything in Wuhan has disappeared. I don't know if this belongs to Meng Xin Jewelry Company. It feels like the name matches perfectly.
