I went to several shopping malls and wholesale companies to buy this wine. You are talking about the rare Red Star Erguotou, some of which are called blue-and-white porcelain, and some are called blue-and-white porcelain. There are two kinds of blue-and-white porcelain: one is 751ML with a dragon pattern on it, and the other is with a blue flower pattern. They all belong to the rare Red Star Erguotou. Some shops sell it exclusively for catering, while others don't write it. Please pay attention to it when buying it.
