　　First, the thickness of the skin, the thicker the thickness of the sheet, the better the durability. After the paint is applied, the solid wood has a strong sense, the clearer the texture, and the brighter and more saturated the color. The identification method of the thickness of the sheet is: observe whether there is sand penetration and glue penetration on the edge of the plate, and whether there is bluishness or bottom penetration in the water coating test. If the above problems exist, the skin is usually thin.
　　Second, the material of the bottom plate, the material of the bottom plate is eucalyptus wood, and most of them are poplar cores in the market. It is necessary to make a specific judgment: look at the weight of the bottom plate, most of the heavy ones are eucalyptus or other hard miscellaneous woods, and the light ones are poplar; second, the color of the medium plate, the very uniform white or the medium plate that has been dyed and masked is generally poplar. 3. Whether the board is warped and deformed, whether it can be erected vertically, warping occurs naturally when it is laid flat, or the board is soft and not stiff and cannot be erected, it is an inferior bottom plate.
　　3. The manufacturing process can be judged from the aspects of slice slicing and splicing and pasting, seam processing, defect repair process, sanding defects, bottom plate defects and other appearance damage and pollution. Generally, people with normal vision are visually inspected at a distance of about 1-1.5 meters. There are no process defects, bottom plate defects, artificial damage, and pollution that affect the decorative beauty. Those with obvious visible and more serious defects are generally downgraded to the first grade or qualified.
