You can ask the merchant for the floor head of the selected floor, use a metal key or nail to scrape and scratch the floor surface several times, and then rub the scratched area repeatedly with the palm of your hand. If there are almost no scratches, it means that the scratch resistance is relatively good; if you can see more obvious scratches or the bottom board, it means that the wear resistance of the floor is not up to standard and the quality is not good. lt；/P
