A tea tray is used to place teaware. It has many different materials and various styles, such as round moon shape, chessboard shape, etc. But no matter what material and style, the most important are the two characters: wide, and flat. It means the tea tray should be wide so that it can place more teacups when there is more guest. And the bottom of the tea tray should be flat, so as to make the cup stable and uneasy to shake.
