Is there a buy one get one free wedding reception in Fang Jun Shuanggou Treasure Square recently? How to distinguish anti-counterfeiting?

There seems to be. I've seen it in many places. I also held a full moon wine and said that there was this activity. The dealer swore that it was genuine, and indicated on the invoice: one fake and one penalty, and signed it. However, I only hosted the banquet on 10 this month. I bought it at the original price and got it back. The gift said it was delivered directly to the hotel on the same day. If you can wait, I'll tell you my situation after 10.
