This is a school photo, but after it was taken, it was the strangest photo in the world, and everyone who could understand it was shocked. Did you get a look at him?

First of all, everyone knows that the group photo was taken face to face, right? I didn't shoot back to back. Some people will say that it may be a group photo, and someone is taking pictures in the back. Then the problem is coming. On the front, the row is higher than the row, and the people in the front row are blocking the people in the back row. According to graduation photo's children's shoes, it can be seen that teachers in graduation photo are generally at the forefront, but why does this teacher stand at the end? There are signs that they are taking pictures of graduation photo's back. Take a picture of your back. . . There is another possibility. Oh, maybe, they have backs on both sides.
