The elements are background, visual, content, value.
Let's address them one by one.
The background is an overall presentation of your streaming environment, which will determine the main tone of your broadcast.
You may not feel its importance now, but as the industry develops and competition intensifies, more and more streamers will certainly put effort into their background.
Let me give you a very simple analogy—
Suppose you leave your rental apartment and start broadcasting from your rural hometown, with the background being an old room, peeling wall paints revealing soot-blackened red bricks, a row of awards from elementary school plastered on top, an old-fashioned thermos and enamel basin on the right side, and a stack of red floral cotton quilts on the earthen bed on the left.
