Look: The surface of a high-quality blockboard should be smooth, flat, and defect-free. Check from the side whether the thickness of the board core is uniform and whether there is any overlap or separation from the core.

Listening: If you want to know the intrinsic quality of the blockboard, listening is also a better way. Use your hand or other blunt instrument to tap the surface in different parts. If the sound is very different, it means there is a certain quality problem, and there may be a cavity inside. If the sound is more uniform, it means the quality is acceptable.
