Tea trays are used to hold teacups, and there are many materials and styles, such as full moon and chessboard. But no matter what material and style, the most important thing is the four-character formula: wide, flat, light and white. That is, the disk should be wide, so that more cups can be put according to the number of guests; The bottom of the plate should be flat to prevent the cup from being unstable and easy to shake; The edges should be light and the color should be white, all to set off the teacups and teapots and make them elegant.
