Write whatever project you run, for example, your family is engaged in barbecue business, and you can write: fresh mutton barbecue, fresh beef barbecue, mutton barbecue, Inner Mongolia fat sheep barbecue and so on. If you sell fresh mutton, you can write brand plus fresh mutton, brand plus fresh beef, mutton, fat beef and so on. Like my main display: I write LED color display, monochrome display and so on.
