Retail is of course part of sales. It is something that is excluded from the regular business of the enterprise, and it is scattered, just like what you said about wholesale. Occasionally sell some bulk goods. The income of accommodation and catering industry should be called turnover, as well as retail. For example, the hotel sells several barrels of noodles or mineral water, which is different from the big category in that the source of funds is retail. That's how I understand it myself. I don't think it's right.
