A little joke about product quality

1, I bought a whiteboard when I went home for the convenience of learning a foreign language. Clean and brand-new, the handwriting on it is very clear, except that it is difficult to erase the ink after a period of use. At first, I thought the whiteboard was new, and there were inevitably some problems. But after writing several times, I found the same situation and had to wash it off with soap. I thought there was something wrong with the quality, so I was very angry and wanted to return it to the store. As a result, I rubbed it hard, erased a layer of plastic film, peeled off the plastic film, and erased the words.

If you don't uncover that film, the real whiteboard will always be separated by plastic film. Why don't you think there is something wrong with the product quality, so that the store will be wronged in vain? So is truth. There are so many complicated things in life that we can't find the truth directly. After hitting the wall many times, many people will choose to give up, but only a few people are sure of the truth.
