test whether there are bright spots and dark spots. If you don't know how to ask the merchant to do it for you, just look at it carefully. Don't listen to the business commitment, everything is subject to the warranty. If an individual business has some special extra promises, remember to ask him to write them on the invoice. Otherwise, if it's just a verbal promise, he won't admit it when he comes to him later.
